Do you really have backup iron sights (BUIS) that you can count on? A lot of shooters do not and it’s not just the fault of the hardware

I’m sure there are a lot of shooters like me who buy and install back up iron sites on their weapons just in case the optic fails. Except for pure range toys that will never see use beyond having fun, I do think BUIS are a really good idea – optics fail for any number of reasons with batteries being dead quite possibly being the #1 issue – especially given how folks love their red dot, green dot and holographic sights. You need a backup for aiming your firearm.

What happens if the battery in the Vortex dies? Well, I do have the backup Magpul sights … right?

A quick comment about “BUIS” – it stands for Back Up Iron Sights. I’m a creature of habit and that’s how they were first introduced to me but not everyone uses that term. For example, Magpul calls their units MBUS – Magpul Back-Up Sights. Other’s just say “back up sights” or even just “attachable” or “folding” sights. So, if you are wanting to search and see what your options are, it will take some searching.

Four Camps of BUIS Users

In talking with shooters, regardless of their firearm platform (AR, AK, Stribog, HK, etc.) about their BUIS, I usually find they fit in one of four camps:

  1. Installed the BUIS and run them full time with their optic in a co-witness manner
  2. Installed the BUIS and periodically use them in a co-witness model but fold them down when not in use
  3. Installed the BUIS and only use them when needed but did sight them in. For example, if they need to remove the optic to deploy the sights or are using offset sights and tilt the weapon 45 degrees to use them.
  4. Attached the units to the Picatinny rail, did not sight them in and have never actually practiced using them to hit targets at the range … “but have them just in case”.

With scenario #1, you know those sights will work – it doesn’t matter if the scope is powered off as long as you can see through the glass.

With #2 & #3 – the sights will probably work as long as you can see through the glass or otherwise see them. Hopefully the shooter has practiced enough how to use the units.

The last one is the most concerning – camp #4 – to be honest, a person in this camp doesn’t really have a backup. Yeah, they have the sights but they aren’t dialed in and lack experience with them. This is a gamble you do not want to take. If this describes you – please don’t take it personally and read the next section – I want to help.

As far as I know, all BUIS are two parts – a front sight and a back sight. In the above photo – I am using Magpul polymer MBUS folding units and are on each far end of the top rail. They fold down until needed and then spring p when you push a lever on each.

If You Are In Camp #4…

First off, I am glad you invested in BUIS – if you are reading this and you haven’t yet, then do so. With that said, do you have quality units or did you buy something dirt cheap off Amazon or eBay. I’d recommend going with a brand name and not cheap airsoft import stuff – I like Magpul (they have a ton of models so click here to see them) plus, in all fairness, there are other quality BUIS sets from the likes of ARMS, Bobro, DiamondHead, Troy and others. Cheap stuff may not hold their zero or break easily. Buy quality to have true BUIS that you can count on.

Second, make sure they are mounted properly. Did you follow the instructions from the vendor who made them? Sometimes there is more to do than slap them on the Picatinny Rail.

Your backup sights should have come with instructions and any specialized tools – be sure to read and follow them. The little black key you see is used for adjusting a Magpul front sight.

Second, you need to sight in the BUIS. I use a laser to help get in the ballpark in the shop and then I do the final tuning at the range. Read up on the recommended range for your firearm and type of optic. For rifles, I go for 50 yards because then you are then zeroed for 50 yards and at 200. The BUIS are just that – emergency backups. I look to be in the ballpark with them and am not looking for perfection but some guys are amazingly proficient with them.

Third, absolutely take them to the range and practice with them!!! Buying, installing and zeroing the BUIS are only part of the game – you must also know how to use them. If they fold, practice on opening and closing them while shooting. If they are offset, practice transitioning to them. Bottom line, you need to practice hitting targets with them and adjust the sights and what you are doing accordingly. The more you practice the greater the odds that things will work when you need them. If you don’t practice then you are taking a huge gamble both on the BUIS and your ability to use them – so don’t gamble.

Magpul sells both basic polymer and pro steel versions of their MBUS. Above is a polymer rear unit on one of my ARs. I fold both the rear and front sights flat until needed – the small lever you see to the left of the mounting screw both releases the sight so it flips open via a spring and then locks up up right. I can count on them because they are zeroed and I practice with them.

Summary

The whole reason I wrote this is that it seems like I have encountered a lot of shooters this past year that had BUIS and fell square in camp 4 – they had never sighted them in or practiced with them. This is very concerning to me – they are gambling on something that shouldn’t be left to chance. So, yes, I think BUIS are a great idea but you need to sight them in and regularly practice using them also. If you don’t, then your backup probably isn’t a backup.

I hope this gives you some food for thought.

Gunsmithing, Optics

Use a Wheeler Engineering Green Laser Bore Sight To Get Your Scope or Optic Range Ready

When you buy a scope/optic and mount it on your rifle or pistol, it may relatively be close to where the actual bullet will hit the target or it may be a mile off. This applies just as much to dot optics as well as scopes with magnification. First off, this is why you need to sight in any type of optic before you use it. Second, unless you want to waste a ton of ammo, this is why you want to bore sight an optic before you do the final adjustments.

“Bore Sighting” refers to looking down the bore, seeing the target and roughly dialing on the elevation and windage of the optic. This was never perfect but it at least got you on the paper at 25-50 yards you could then start dialing in the scope and backing up to whatever range you wanted to dial the scope in for. This method worked fine if you could actually remove the bolt and look down the scope, such as a bolt action rifle. It doesn’t work for semi-autos where you typically have a closed rear receiver and can’t look down the bore. It also doesn’t work for folks like me who can’t see the broad side of a bright red barn when trying to look down a bore.

The industry responded with all kinds of gizmos to help improve the process ranging from calibrated collimeters that let you roughly sight in by pointing at some target held up from the end of the barrel. That lasted for a few years until lasers started getting affordable and then models started popping up that either went in the muzzle with some form of collet to help center the shaft in the barrel or there were ones that approximated the shape of a given round and went in the chamber. The accuracy of either one greatly depended on the quality control of the manufacturer. In general, they worked and were really simple – put the laser in, turn it on and then dial in your scope to where the red dot was showing.

Pros: Simple, cheap, did the job Cons: acccuracy was highly dependent on how well the manufacturer made the unit, they are impacted by how well the inside of the muzzle device aligns with the barrel and the red laser faded out quickly in bright light and because they all use button cells of varying sizes the battery life might be short – especially the fake cartridge units. Note, a number of the muzzle end manufacturers do offer green lasers and that helps. Bottom line, they do the job and I do favor the muzzle end devices more provided they are from a quality manufacturer.

Then along came Wheeler Engineering with relatively large green laser unit with a strong magnet that sticks on the face of the muzzle (the end of the barrel). This got away from issues with the muzzle end units not centering and the frequent poor quality of the imported fake cartridge units. The green laser is powered by a relatively large CR123A battery that is the same used in many tactical lights. I should point out that they make a red laser version too but if I had to pick I would go with the green laser as your eye can see it easier and it reflects from further away.

This is the Wheeler laser bore sighter and it is the green laser unit. Note, I have a bettery in the unit and a spare Surefire CR123A in the holder. Steer clear of no-name cheap CR123A units as they have had issues in the past and caught fire, burst, etc.

I’ve used it for a few years now (I bought it in 2019) and have found two issues that affect it. First, the end of the barrel or your muzzle device (flash hider, muzzle brake, and so forth must be steel for the magnet to stick to it. By the way, I am not impressed by how aluminum muzzle devices hold up over time and just buy steel whenever I can.

The second shortcoming is that the manufacturer of the muzzle device and/or the barrel must have created a true end meaning the end of the barrel, the thread, the muzzle device – they must all result in an end of the barrel/muzzle device that is perpendicular to the barrel. The worst offenders in my experience are the muzzle devices because their positioning depends both on how well the threads were but on the barrel plus how well the device was made. Some combinations are better than others. If I were to make a generalization, unthreaded barrel muzzle faces from a quality manufacturer tend to be pretty true.

This is a quality Ballistic Advantage 20″ 5.56 DMR barrel. I’d expect its threads to be cut properly. The next variable would be how well the muzzle device engages the threads and how square the end of it is.
This is a IWI Galil Ace in .308. In a favorable nod to their manufacturing the factory barrel and brake yielded a remarkably close test pattern at 25 yards. I’m always amazed when boresighting is within inches and then going to range yields initial rounds within a6 inches of the expected center and this one did.
This is the strong magnet that secures the laser boresight to the end of the barrel or muzzle device. It’s also why either end would need to be steel for it to magnetically attach.
Here’s the unit secured to the end of a PSA barrel and PSA bird cage brake. It did the basic job of getting the rifle on paper with it’s Vortex UH-1 optic.
The power button is on top of the battery compartment and you can see the green laser hitting the off-white plastic cup. I like to sight in when the sun isn’t bright so I can get out 25-50 yards.

As with the other bore sighting devices, this unit will get you in the ballpark. Because of the factors above, you might be on the paper at 100 yards but you are better starting off at 50 and working things out from there.

By the way, one tip of any of them is to do your boresighting early in the morning or at dusk but not in the bright light of day. You can reach out 25-50+ yards and see the dot enough to do the initial sighting.

As a closing comment – none of them are perfect because they were all designed to be approximations. The final sighting must be done by you with the rounds you expect to use because a ton of variable will affect where you bullet actuall hits – your cheek weld, your trigger pull, factors with the bolt and barrel, how consistent the ammo is, the weight of the bullets, etc. My goal is to save some ammo and at least hit the target so I don’t have to shoot so many rounds to dial in the final settings and then begin working out firing solutions for different ranges.

In Conclusion

There actually isn’t a perfect solution – I mainly use the Wheeler Pro Green Laser Boresighter when I can but I still have a couple of good muzzle end units that I use when the muzzle device is aluminum. I know one unit is from LaserLyte and I really do not recall who the other is from. I do not use the dummy cartridge units after a few disappointing tries.

So, if you haven’t tried a Wheeler Pro boresighter and are in the market, I like mine.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

The ATN X-Sight 4K 5-20x Scope Is Surprisingly Effective But Expect A Learning Curve

I never was that interested in ATN scopes until maybe a two years ago. I was at the range fiddling with something and a fellow pulled in and set up a varmint AR with a big blocky optic on a Bog Deathgrip tripod. I could not help myself – I had to go over and ask what the optic was.

Thankfully, he was a good old boy and liked shooting and talking. He was having a coyote problem and wanted to get the rig sighted in. He told me it was an ATN night vision optic and the tripod was to help him keep it all steady. I looked it all over and headed back to my area. The ATN looked better in person than it did in the ads that I had seen in catalogs that made it look “gimicky”. Between my assumption about the quality and the price, I was never interested but after seeing it in person it was filed under “who knows – maybe someday” category in my head for future projects.

Fast Forward to 2021

I was researching high end airguns and some of the of guys were running various ATN scopes. I wanted to up my game on the computational ballistics front – yeah the calculation of trajectories – and I wanted a computer to do it for me. I really wanted to get surgical and modern with my new .25 caliber FX Impact Compact pre-charged pneumatic (PCP) air rifle. This desire brought me to ATN and their latest generation of digital X-Sight 4K optics because they have an internal computer that can crank the numbers.

An Auxiliary Ballistic Laser (ABL) good from 5 to to 1000 yards could be added that interfaced with the scope to provide range to target data to the computer. The computer can take the muzzle velocity of your round, the ballistic coefficient of your bullet (in my case pellet), distance of the optic from the center of the bore, angle and the distance to the target and automatically adjust the recticle. Whoa…. that’s pretty amazing.

Just a quick note on the ABL – based on my experience with laser rangefinders, usually maximum range comments by vendor are a bit of hype because it depends on how reflective the target is. In my case, virtually all of my shooting will be within 50 yards with a possible stretch to 100 but I doubt I will ever shoot beyond that.

Another feature that attracted me was the night vision capability. I’ve not had the capability to eliminate pests at night or at very low light levels.

The X-Sight scopes have a host of other features like taking photos and movies, recording just before and after sensing recoil, etc. Those are nice but not really features I cared about.

I shopped around and ordered an ATN X-SIght 4k 5-20x optic, Auxiliary Ballistic Laser (ABL) 1000 rangefinder, and a quick release mount. It came to just over a $1,000 plus I bought a SD memory card. The optic and rangefinder were from Brownells and I sourced the quick detach mount direct from ATN. A lot of vendors carry ATN products so you can shop around.

In case you are wondering why I would go to such expense for accuracy in a PCP airgun that will mostly be used within 100 yards, I can sum it up with the saying “aim small – miss small.” It’s one of my favorite lines from American Sniper but it is true. If you focus your aim on a very small part of the target then you will either hit it or miss by a small amount. This requires discipline and knowledge on your part combined with a capable weapons system to deliver the bullet or pellet.

The Scope, ABL and Mount Arrived

When the boxes came and I started reading the manuals, I had the same feeling when I read something that says “some assembly required”. I really hadn’t put much thought into how different a digital optic is from a traditional scope. Wow. This thing has a series of setup menus and then you need to learn your away around the scope. So right out of the box there was a lot of fumbling, swearing and my changing things.

So here’s my first recommendation – be sure to watch ATN’s videos about setting up the optic and using it. The manuals help but I found the combination of videos for the overview and the documentation to refer to as a very handy combination. Click here to go to the ATN page with all of their videos and/or click here for the manuals – it actually has links to PDFs videos and guidance on the page itself.

The X-Sight is mounted just like any other scope. Square the weapon then the optic to the weapon to ensure the recticle is level. I use a Wheeler scope mounting kit’s leves to do this. Note that the Impact Compact is being held in a Tipton Standing Ultra GunVise. Man, those are nice.

Here’s an example of needing to read the instructions. The threaded portion is part of a tube that is separate from the body of the ABL. You back off the two screws you see, remove the tube and screw it into the front of the X-Sight scope. You then clamp the ABL onto the tube and position it horizontal to the scope and bore.

Here is everything mounted.
Here’s another angle.

Now let me give you hope – once you start using the scope, it gets easier and faster each time. I turn on the scope so it has time to boot up as I am setting up – not at the last minute when I need to take a shot. Most of the time I am shooting at 14 yards so I dont need to range the target and the scope remembers the last range used. Instead,I zoom as needed, acquire the target and take the shot. That’s it – not a billion menus. So, stick with it – you will probably find it frustrating too at first and then it will get better with time.

Setup and Zeroing In Tips

When you are entering the info for the ballistic coefficient (BC) and the muzzle velocity, try and be as exact as possible, I obtained the BC from the manufacturer of my .25 pellets and the muzzle velocity was the average of 10 rounds fired through a chronograph.

I carefully measured out the range from the muzzle to the target. When I entered the range into the optic, I was precise and not guessing. I was being very careful due to the desire for accuracy.

Set your rifle up in a firm stand and fire a group then adjust the recticle. Their marketing comment of one shot zeroes is something they even mention is “in theory”. Repeat this until you have your zero consistently. This will all go faster and be easier if you have a solid stand – notice I mentioned this twice now 🙂 I used a Bog Deathgrip Carbon Fiber model to help me get the job done.

My Opinion

I’ve been using the X-Sight since late-April 2021 and like it. If I have a new distance to shoot, I range it, take the shot and then reset to my most common distance. I have made a few 35-50 yard shots that would have required some calculation, or at least experience, and hit less than quarter sized targets (squirrel head and heart shots) accurately.

Here’s another angle that gives you a good view of the mounted ABL. It connects to the scope via Bluetooth and you need to follow a zeroing process outlined in the manual. It’s straight forward but don’t skip it.

One thing I had to get used to was looking at a small monitor vs. glass. I’ve been shooting nice glass scopes for a number of years now – notably Vortex scopes – and looking at a monitor with a resolution lower than reality is different. I must admit that I prefer the clarity of good glass but it dawned on me that it was not fair to compare them at this point. I bought the ATN for the ballistics calculation capabilities and the potential for low-light/night-use — I did not buy it to be just another scope, That set my mind more at ease about the image difference – it is what it is with the current level of technology in these scopes.

This is an actual screen capture. The optic allows you to select from a number of recticle choices. Note the range information from the ABL down in the ower right corner. What you see in the scope actually has much more information but the screen capture does not include it.
This is an exciting shot of concrete but it lets you see the recticle better.

The combination of scope and ABL is a bit bulky and the ABL’s head is asymmetrical for the laser transmitter and receiver units. I set the Impact Compact on our tall kitchen table and it fell off onto the hardwood floor about three feet. It definitely made my stomach drop to hear all that money hit the floor. I’m actually happy to report that the rifle and optics system survived without any problems at all.

I was wondering how long the battery would live but that has not proved to be a problem. I fully charged it when I first got it and then again a few weeks ago. Now I don’t leave it turned on all the time. I’d say it runs maybe 5-10 minutes every 2-3 days and it’s not been a problem. I think I will just always charge it when it gets half way down or so plus I could always charge it from a powerbank/portable battery if needed. ATN even sells an extended battery if you need it.

The ABL is still on its first battery so I can’t tell you much there – I only use it as needed for longer shots so its had minimal use. I do have a spare battery just in case.

I wish the menus were a bit easier to navigate with very clear “back” or “cancel” options immediately available on every screen. For example, if you get into the manual ranging section or the part of zeroing the recticle by accident. For the most part they are pretty straight forward but I am not wowed by them from a user design perspective.

I opted for the ATN quick connect scope mount and it is okay but does not have locks on the throw levers. In hindsight, I could have used any 30mm rings I wanted including my preferred American Defense mounts. You have plenty of flexibility because one of the menu options lets you specify how high the scope is mounted.

Here’s a view of the ATN quick dtach mount’s levers. They don’t lock closed but have held no problem so far.

Last comment – I had the scope freeze on me twice. I found that turning the ABL off first, if I turned it on, seemed to cause the problem. Now, when I do use the ABL, I turn the scope off first and then the ABL. I’ve not had it freeze since powering down in this order. By the way, if your scope does freeze, hold down the power button for 10-15 seconds and it will shut off – kind of like notebooks where one push does a controlled power down of the laptop but holding it down does a forced immediate shut down.

ATN definitely tries to label everything outside of the scope to try and help folks learn the controls.

In Summary

I’ve been using the X-Sight 4K 5-20 and ABL 1000 laser for about three months and several times per week – sometimes several times per day depending on what is going on. I really feel like the combination has improved my actual accurage in terms of precisely hitting the target so I am happy with the purchase.

I’d recommend the setup for anyone looking for this type of optics system with similar intentions as I outlined at the start. It’s different from traditional glass lense optics but it brings a different set of capabilities to the table also. Let me put it this way,I would buy it again for my intended use.

I hope this helps you.

What Is The Best Optic For A Yugo M76 Rifle?

I did a series of posts back in the Fall of 2019 about a custom Yugo M76 that I had Two Rivers Arms build for me that I then added my own optic to [click here for the series]. A fellow recently contacted me about what optic he ought to get for his rifle, I replied and it also occurred to me that more explanation would make for a good blog post.

What is a Yugo M76?

It is a smei-automatic 10-round Designated Marksman’s Rifle (DMR) designed and built by Zastava for the Yugoslav military chambered in 8mm Mauser (7.92x57mm with an IS or JS designator at the end of the size). The 8mm Mauser round is in the same ballpark class as the American .30-06 round to give you a rough equivalent.

Let me revisit the “DMR” designation – because that is what the M76 is. The M76 was designed for a designated marksman in a squad to have much further reach than the rest of the team would have. It was not a surgical weapon and instead stressed reliability and good enough accuracy with an effective range of about 800 meters with 1.5-2 minutes of angle (MOA).

This photo is from Wikipedia and it lets you see the ZRAK optic on the M76. By the way, Wikipedia does have a nice summary write up on the M76.

What does that tell us?

That short intro starts hinting at the type of scope you might want to consider. It’s firing a relatively powerful cartridge but isn’t the most precise rifle on the planet. I can also tell you that while there is recoil, it’s not bad at all.

Choice #1 – Mounting Styles

The very first thing to consider is what type of mount you wish to use. The M76 inherits the robust side-mount rail but with some unique dimensions. The rifle was originally paired with an offset 4x ZRAK scope that slid onto that rail and clamped into place. This offset design isn’t for all folks but it definitely works for people familiar with it.

Here you can see the optic side mount rail. It sits securely in a groove in the milled receiver and is riveted in place.

The second route is to get a mount that clamps on the above rail but then centers the optic over the centerline of the bore. Call me an old school American but that is definitely my preference.

You can get mounts this way that directly hold the optic directly with the scope rings being built directly into the mount or you can get mounts that have a Picatinny rail on top that you can then secure whatever optic you want. This is my preference just so you know because it gives me more flexibility down the road.

RS Regulate mounts are the way to go!!

The best side mounts I have found that enable a ton of flexibility and adjustment are the RS Regulate brand mounts designed by Scot Hoskinson. He offers a number of different options so you need to stop by his site and take a look.

This is the RS Regulate AK-303M lower paired with the AKR upper rail.

Note, RS Regulate mounts are being counterfeited in China. I’d recommend only buying direct or from a reputable dealer below:

What optic to use?

On one hand, you could stick with the communist block styling . You can hunt around and buy 4x ZRAK optics still. There are also a lot of different offset mount optics that you can look into that are side mounted for example 8x and variable power. Just confirm the clamp on a particular model has enough adjustment to fasten onto the M76’s rail.

As of my writing this, there aren’t any ZRAK scopes on eBay but Apex Gun Parts does have some in fair to good condition (meaning very worn) and they are a good firm to deal with. Kalinka Optics has a variety of offset mount optics and is also reputable. If you really want an offset scope, I’d recommend Kalinka and go with something new.

With that said, you may be wondering “but what size scope?” The 8mm round definitely has some reach and you have to ask yourself what do you really plan on doing? This “what am I going to use it for” question is known as the “use case”.

When the Yugoslavs designed the M76, they needed a middle of the road simple optic that would allow the shooter to hit something man sized out to 800 meters. Four power magnification fits that bill because it gives you a wide field of view (meaning what you can see left to right and up and down in he scope – the more you see, the wider the field of view). They weren’t looking for precision by any means – just good enough to extend the reach of the shooter.

I’m 53 and while I grew up shooting a lot with iron sights, I can’t see very well at 100 yards and I sure can’t shoot precisely. Now remember, the M76 you have will likely be shooting1-4 MOA (1-4″ at about 100 yards, 2-8″ at 200 yards and so forth). It all depends on the condition of the rifle and the type of ammo you are shooting not to mention your own abilities. Spending a fortune on a giant quality surgical scope, like a 6-24x, is overkill…. unless that is what you really want.

What I would recommend is a variable power and I tend to favor 4-16x because I have the nice bright field of view at 4x and can zoom in if needed. Most of my shooting is within 200 yards so this works just fine for me on my DMR rifles.

Now you may be wondering “But I saw the photo of that giant scope you are running – what’s up with that?” Good question and let me explain.

That’s a Vortex Crossfire II 3-12×56 scope known as the “hog hunter” and my buddy shooting it during a range visit this summer.

My “use case” when I was planning for the optics was for hog hunting. I wanted a really big objective to suck in light for shooting at dusk and an illuminated recticle. I also happened to already have it left over from another project. It is quite affordable by the way.

So, the Hog Hunter seemed like a great match – 3-12x for fast shooting in close to having a 12x for distance shots. The big 56mm objective does pull in a lot of light. The lit recticle is only bright enough to make a difference at night and isn’t as bright as what you would see on a tactical scope.

Having used it for a while now, I’ll tell you that it delivers on the above with a couple of caveats that may make you stay away from it unless thye don’t bother you:

First, it is a big scope – far bigger than what you may think in terms of dimensions and weight due to the big objective. It’s almost 13.5″ long and 21.1 ounches.

Second. it is a giant objective and you will need to plan for. I had to carefully calculate the rings needed for it to clear the front handguard and I needed them to be quick release because the scope mount could not slide backwards due to the big objective hitting the rear sight block (RSB) of the rifle. I am still using the AD-RECON-SL mount and it is solid!

For a lot of folks, starting with an objective around 40mm tends to give you a nice bright image. I tend to use 44-50mm objectives scopes the most. Think of it this way – the bigger the objective, the more light it can pull in all other things being equal.

So where am I at today and what scope would I recommend?

I still am running the Hog Hunter and like it. If I had it to do over,I would get a 4-16x magnification and a 44-50mm objective. Recticle-wise, I’m fine with just about anything for what I plan to use it for but if I were to specify one, I’d get one with Mil-Rad (Mil-Dot) graduations because that is what I am familiar with.

There are also other variable zoom scopes out there as well such as 2.5-10x, 3-9x, 1-6x, 1-8x, etc. These are all options if you still have good eyes and want an even wider field of view on the low end. I run all of those combinations on rifles where I plan to be relatively close and not so much for long distance. Point being it is up to you – I wanted a higher power scope for shots starting often at 100 yards.

Vortex makes really good optics and I would move with whatever I could afford at the time. What you will notice is that as you move up their product line , the bigger price tag also comes with clearer and brighter optics *but* they all have Vortex’s no nonsense warranty.

I am going to present their various offerings that I would recommend and am able to show the scopes listed at various merchants as well so you can shop around:

Let’s start with their entry-level Crossfire II scopes:

Next, let’s look at the Diamondback and Diamondback Tactical series scopes:

The following are Strike Eagle scopes and the designs are focusing more on tactical versatility.

Even higher end are the various Viper HS scopes. I have a number of these and find them to be bright, clear and rugged:

My favorite Vortex scopes that I afford is the Viper PST Gen III series. Yeah, budget does have a role and have not been able to afford a Razor but the PSTs excellent. When I can afford a really exceptional optic, I look at the PSTs. A number of vendors still carry Gen II scopes and they work great also. I’ve had several Gen IIs and only one Gen III so far.

In Conclusion

I hope this helps give you some ideas of what optic to put on your M76 rifle. I really like Vortex Optics and am a user – I’m happy with the Hog Hunter but it is big. I think you’d be very happy with just about any of their scopes depending on what you want to do.

Changed my Yugo M76 Scope Mount To An American Defense AD-RECON-SL and It’s Rock Solid!!

When I was adding the big Vortex Hog Hunter scope to my M76 with RS Regulate side mount optics rail, all I had to prototype with were UTG rings. While the UTG rings aren’t too bad, I have stopped using them with centerfire rifles because they have a rounded screw that passes through the Picatinny rail rail slot. It’s rounded shape and only partially filling the slot risks damaging the rail and the zero shifting because the ring(s) can move.

These are the UTG low profile rings. Note how the screw is round and not rectangular? Also, after 30 rounds of 8mm Mauser firing, the rear flip lever rattled loose.

What is really needed is a quality ring or scope mount that uses a bar that properly fits into the Picatinny Rail slots and locks the optic securely and consistently into position. American Defense mounts are that way and they have an excellent locking lever.

I started using American Defense mounts for my Vortex Crossfire Red Dot optics a little over a year ago and was very satisfied with them and very impressed by their quick release lever design. So, when I needed a new mount for my M76 that was strong enough to hold the big Vortex Hog Hunter scope on my M76 and would clear rear sight block but also be close to the bore, the American Defense AD-RECON-SL immediately came to mind.

American Defense AD-RECON-SL

American Defense started with their QD Auto Lock System – the quick release lever system they developed. – and have branched into a variety of offerings from there including scope, bipod, light, laser and other mounts. In short, they are capitalizing on their really rugged QD levers.

So, the first thing I did was to measure the UTG mount from the top of the rail to the optic center, which I used the top of the lower half ring. That measure came to about 0.975″ and I knew any mount I bought had to be at least that or bigger. The front objective was all but touching the gas tube cover with those UTG low rings.

The AD Recon series has a variety of heights and offsets to select from and they publish specs for you to make an informed decision. In my case, because the RS!Regulate side mount already has front-to-back adjustment, I didn’t feel that I needed any offset but I did want to find as low of a scope mount as I could.

In looking at the specs, the AD-RECON-SL seemed to fit the bill. It had no offset and was their lowest mount with a 1.110″ center for scope with a 30mm tube. it was a tad higher but the slightly higher 0.135″ difference really didn’t worry me so I went ahead an ordered one.

Folks, the AD-RECON-SL did not disappoint. It is really a gorgeous piece of engineering. The fitment is excellent and is finished in a black hard coat. Here are some photos:

Here’s the side of the unit with the adjustment nuts. I love the flag on the side.
Here it is with their patented QD levers. The small lever you see in the middle of the bigger lever is the locking mechanism that keeps the unit secure. The moment you flip those rings you know your dealing with quality.
See how American Defense uses bars to lock the mount into the Picatinny rail? This is the way to go. It makes for a very secure and consistent engagement meaning your optic’s zero will not shift and the rail will not get damaged over time under heavy recoil with a simple round screw.
Yeah… that’s the American Defense unit on the left and the little UTG ring on the right. I would have no hesitation recommending the UTG rings for a rimfire or light recoil applications but not for something where there is significant recoil and a heavy optic combined.
Here’s another angle.

But Why Have QD Rings on a RS Regulate Mount?

I do need to explain this. I can bet that I will need to take the dust cover off for some reason and don’t want to rely on tools. If I am hunting, I may not have any tools with me and need to clear a jam or something. That means I need a way to remove the scope and rail to get access to the dust cover.

The RS Regulate’s lower rail does have a quick take down lever that solidly clamps on the M76 rail. That is not the issue and may make you wonder I need another quick release system. The challenge is that the Hog Hunter scope has a giant 56mm front objective for gathering as much light as possible in low-light situations such as dusk. It will hit the M76’s rear sight block if pulled straight back when mounted as low as I want. The solution is to use the AD-RECON-SL optic mount to enable me to lift the scope off the RS Regulate’s top rail and then I can slide the RS Regulate assembly off. The combination definitely works.

Installation

Taking the mount apart was easy – remove the four screws on each ring. I was pleasantly surprised that they used a precision pin to guide the rings into position and not just the screws. Again, this makes it stronger and more consistent.

Here’s a close up of the base. The middle hole is for the guide pin and the outer holes are for the screws.
Here you can see the four halves of the rings. The half to the top left with the guide pin. Its counterpart is already installed in the back.
An important design aspect to note is that the halves are not symmerical from top to bottom. The side with the pin is a no-brainer – that goes in the base. The other two halves without pins need to have the thinner section at the bottom for the pieces to mate up correctly. You can see in the top left half that the bottom part with the alignment pin is not as tall as the top. The lower-right is also a good angle for you to see the thinner bottom relative to the top.

There is an installation detail that you may not guess and they detail it in their installation instructions – you install the bottom screws first and tighten them down to the 20-25 in/lbs torque spec first. For folks not used to working with small fasteners, please note that is inch pounds and not foot pounds).

The bottom is torqued down first and then the top. There will be a small gap at the top. This method of bottom then top torquing centers the optic in their design. The only thread locker they will recommend is VC-3 Vibra-tite and the use of anything else will void the warranty. I’ve used a lot of Vibra-tite with Kydex holsters – it’s interesting in that you clean the fastener, apply the VC-3, let it dry and then assemble. It creates a rubbery surface that pretty much negates vibration. It also stays put when you unscrew and reinstall screws. It’s interesting stuff. They include a small packet of it with the mount but I also keep it around for working with Kydex fasteners and other situations where I expect there will be a need to uninstall and reinstall or adjust screws.

Here’s the M76 rifle with the American Defense mount installed. Note I used my Vortex torquing screwdriver to do the installation. It’s definitely a precision instrument and what I use for all optics work now. I take care to return it to zero after each use.
Here it is from another angle.
I changed cheek pieces to get a better cheek weld. This unit is nice and stable. I’m so-so about the cheek pad itself and wish it was a bit wider but it is better than the Voodoo cheek pad that was there. I’m still hunting for an even better cheek weld and have some options I want to try that I will report on at a later date after I have a chance to try them. To be clear- it is a solid cheek piece and the right height but personally I do not like the feel of that relatively narrow riser.

In Summary

The combination of the RS Regulate side mount system and the AD-RECON-SL optic mount is absolutely rock solid as in zero flex at all. even with the big and heavy Vortex Hog Hunter scope. I really think I have the ideal optic solution now for the rifle. The length of pull is better thanks to the installation of a SVL slip-on Limbsaver pad. I still need to find a better cheek piece to get my eye just the way I want it comfortably behind the scope and have some options to try. Last thing to report is that I did do some work on the firing pin but haven’t had time to test the rifle again.
