How to add an AR stock to a Zastava M77

Okay, some guys hate AR gear on AKs and if it’s not your cup of tea, that’s fine. I do like AR stocks and have no problems putting whatever stock on whatever family of firearms. I’m more into pragmatism and making a firearms do what I want than arguing over AR vs. AK or whatever. This is also why I have commenting turned off on the blog.

At any rate, even before I bought the M77, I knew I was going to trick it out for my purposes and I wanted to put one of the Magpul PRS Lite stocks on it for a few reasons:

  • I like adjustable stocks like the PRS but don’t need to constantly change the length of pull or the comb (where your cheek sets) thus I didn’t need to spend the money on a full blown PRS Gen 3. By the way, in case you are wondering PRS stands for “Precision Rifle/Sniper”.
  • The M77 will never be mistaken for a carbine given its length nor do I need to collapse the stock so the fixed postion PRS Lite was fine by me.
  • There are aftermarket thick recoil pads you can put on a PRS to absorb recoil.
  • By using a buffer tube, I can slide in a mercury recoil suppressor to add weight, absorb some of the recoil and balance the rifle out a bit more to compensate for a long barrel and relatively heavy front end.
  • Last but not least, the PRS Lite reminds me a bit of a PKM stock due to the skeletonized opening. (I’m sure someone just spit their drink out reading that). I had a new mint Romanian PKM stock many years ago that I sold at some point and still wish I hadn’t. In short, I like the looks.
  • Also, the PRS Lite is a bit cheaper than a PRS Gen 3 but that wasn’t a big factor for me – the PKM look is actually what tipped me in the direction of the Lite model.
This is the MagPul PRS Lite. It’s definitely a solid stock that I like – it does what I need it to.

Parts you will need

  • Zastava/Yugo to M4 adapter – this screws into the square hole in the rear trunnion and then presents the hole the buffer tube screws into and the end plate. Go with an aluminum model from a reputable vendor like Ace, JMac Customs, Desert Fox, etc. Note, JMac went a very different route with their pioneering 1913 Picatinny rail interface for the stocks and I provide more details down during installation.
  • A buffer tube – I’d recommend a M4 six position Mil-Spec carbine buffer tube for the greatest flexibility. Rifle length tubes are rarely used on new firearms now as people want the adjustable stocks. Commercial sized buffer tubes were due to some things Colt did many years ago and thus on the way out so go with Mil-Spec which refers to the outer diameter of the tube.
  • An AR end plate – on an AR, this plate keeps the selector spring captured and also aligns the buffer tube via vertical key that sticks up and keeps the carbine buffer tube from rotating – it does help to have it for that reason and you have tons of options out there ranging from the basic to ones with sling hooks and even QD sling sockets. Not all adapter support an end plate so this might not be needed,
  • A castle nut – this nut is threaded on the buffer tube and then tightened down against the end plate to secure the buffer tube in place. Note, you will need a spanner wrench or specialized castle nut wrench of install or remove a castle nut without tearing it up – I recommend the Magpul wrench. By the way, the castle nut gets its name from looking like a medevial castle’s crennelated tower. Crenels are the parts that stick up like teeth to give defenders some protection.
  • Finally, whatever stock you want. Just remember to match the buffer tube to the stock. If you get a rifle stock and it needs a rifle buffer tube then get a rifle buffer tube, etc. The PRS and PRS lite have an adapter and can work with either tube type but most stocks designed for a carbine can only work with a carbine buffer tube (just make sure you match on either the Mil-Spec or commercial diameter).

Removing the old stock

The first step is to remove the recoil pad which is held in place by two beefy wood screws with allen/hex wrench sockets in them. Remove them and then the recoil pad will pull off. You then remove the buttstock bolt and the stock pulls out of the end of the rifle.

Remove these two beefy screws and the recoil pad will pull off. I’m happy to see a modern screw head vs. slotted. I would have been even happier if they were torx screws this is a nice upgrade from the old days.
I kind of felt like Crocodile Dundee when I first saw the new recoil pad screws they are using “Now this is a screw”. If you’ve not seen the movie then the reference is lost but my point is that is a really heavy duty screw.
With the recoil pad off, use a 13mm socket on an extension to reach in and unscrew the buttstock bolt. Yes, that’s a bed. It was super cold out and I set up in our spare bedroom to take these photos.
They’ve shortened the buttstock bolt considerably. I’ve considered having these made but Zastava USA seems to keep them in stock so there is no pressing demand for them unlike our original Yugo military length bolts.
This is what goes into the rear trunnion. The numbering reflects the rifle it was fitted to. Note, these do sometimes get a wee bit stuck in the trunnion so you might need to wiggle it a bit or a few light taps with a rubber mallet and it will pull right out.
This is the rear trunnion and the use of a square hole and big bolt to secure it is one of the unique design changes the Yugoslavs did to the Soviet designs. See the finish residue and chips in there? The snug fitting of the stock, how much the finish has stuck to the metal and a bit of sawdust all combine to cause the stock to offer a bit of resistance during removal. In this case it all came out easily with just a bit of wiggling. You should remove all of that of course.

Adding the new stock

To add the buffer tube, I decided to use two parts that I happened to have in stock. I used an Ace modular adapter (“AKRBY-AR15” is the exact model) and then a JMAC modular stock to M4 adapter that has sadly been discontinued – I bought mine a few years ago so it’s not surprising things have changed.

JMac went a different route some years back and pioneered adapters that expose a 1913 Picatinny rail at the rear to which you can mount a ton of different stocks. That’s another option for you – click here. Once you have that, you add a folding mechanism, then a skeletonized tube (ST) for a cool “I’m not a normal AR look” and then your AR stock if you go that route.

Many, many years ago, Ace Riflestocks was its own company and alos quite a few years back they were acquired by Doublestar Corp – a large AR manufacturer. Same products and quality but you now see a Doublestar logo. Note, there is an Ace to M4 adapter that I have used many times but does not support the end plate. Not the end of the world but a different approach.

If you do not want the modular approach, Zastava also sells a direct adapter. It screws into the rear trunnion and gives you the mount for the M4 buffer tube.

This is the Ace Zastava/Yugo modular stock adapter. Only one of the two rows of screws holes are actually used giving you a bit of vertical adjustment. The adapter is secured by an 8mm allen key socket screw. The screw holes are tapped for #10-32 screws.
The JMac M4-Ace adapter is really well made. The two horizontal screw holes are for securing the Mac Adapter to the modular stock adapter. The bottom opening is for securing the botttom of the AR end plate that in turn holds the buffer tube in position vertically.
Put medium strength Loc-tite on before you install the screws.

If you want to insert a mercury recoil reducer

This next step is entirely optional – I installed a C&H mercury reducer to add weight to the rear and absorb a bit of recoil. The completely sealed 7/8″x5″ C&H tube weighs 16oz. The liquid mercury inside sloshes inside and absorbs some of the recoil. Does it do a ton on it’s own – no. Does it and the weight help mitigate some of the recoil? The short answer is yes.

What I do is wrap tape around the C&H so it fits snug and is roughly centered. I spray brake cleaner in the tub to get any oil out. scuff it up and spray it out again. I then scuff up the C&H tube, clean it with alchol (brake cleaner makes the tape gooey), coat the C&B unit with epoxy and push it in. Some epoxy will come out the drain hole so wipe it off with a rag with brake cleaner and then close it with a piece of tape. By the way, one end of the tube is tapped for a 1/4-20 bolt to help install it. Remove the bolt before everything sets up of course.
That’s not coming out or loosen up. Use a towel with brake cleaner to remove any epoxy on surfaces you don’t want. You need to do this before it sets up. By the way, the longer an epoxy takes to cure, the better it will hold up to shocks over time. Don’t use epoxies that claim to set in just 90 seconds or 5 minutes.

Let’s continue with installing the buffer tube

Put the castle nut on the buffer tubes with the largest slots facing backwards and thread it all the way to the bak, Then install the end plate with the “boss” (raised oval) facing forwards to it will go into the end of the AR adapter. You then insert the buffer tube into the adapter and start screwing it in place. When you can’t screw it in any further because of the plate, back it off a turn, push the plate into the adapter, tighten the castle nut with your fingers. Finally, tighten it down with the caste nut wrench – the torque spec is 38-39 ft pounds (you’ll sometimes ready 40 ft pounds but 38-39 is per USMC TM 05538/10012-IN). If you want to do farmer tight, that is up to you. I’d also recommend staking the nut – putting a divot in the nut in one of the small holes between the end nut and the castle nut so the castle nut can no longer turn without a wrench. Again, up to you.

Here you can see the end plate, the groove in the buffer tube that it travels in and just a bit of the castle nut behind. All are oriented correctly.
I screwed in the buffer tube until the end plate couldn’t rotate, backed it off one turn (or so) until I could get the end plate to slide forward and go in its hole. Note the orientation of the castle nut and it is not tight yet.,
Do you mess with castle nuts a lot? Get a Magpul Armorer’s Wrench. In the photo, the right side is for the castle nut. The left is for the barrel nuts and I don’t use that one much but that castle nut portion gives you a wonderfully secure grip especially when you are breaking ones free. The square hole is for a 1/2″ torque wrench. The oval hole is for rifle receiver extensions and the groove in the castle nut end can be used on the traditional bird cage flash hiders.
Once the buffer is installed, the PRS site can go right on. Just follow the directions with the stock, You remove the screw that holds the front flush cup in place and slide the stock on. You can then put the QD swivel flush cup on whatever side you want.
Both the full blow PRS Gen 3 and PRS Lite stocks have thin hard recoil pads that I always replace. This is a Limbsaver PRS Gen 3 recoil pad that fits both models. It’s well made, fits and feels great. I always make the swap unless the stock is going on a light recoiling rifle like 5.56 NATO. If you want the best recoil pad I have found for the PRS Gen 3 or PRS Lite, get the Limbsaver pad.

End Result

The rifle feels really good and handles well. I think it looks great also!

Summary

Once you know the parts you need, it’s a pretty easy swap to make. Once you get the M4 buffer tube installed you have tons and tons of options out there .

I hope this helps you out.

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.

Finally, ALG AK Ultimate Triggers (the AKT-ULs) Are Back In Stock

I started seeing them two weeks ago and I just ordered two. Folks, the ALG AKT-UL is hands down my favorite AK trigger. Smooth and crisp. I can’t recommend them enough. I like the Enhanced model, which is a step down, but given the choice, I’ll go for the Ultimate.

These have been out of stock literally for years – since before COVID I think, So, they are back but I have no idea how long they will be in stock so snag them while you can.

Why Some Grips Will Not Fit Yugo or Zastava AK Rifles

I am often asked if some model of grip will fit a Yugo surplus or current day commercial Zastava rifle and the answer is a bit of an “it depends”.  Let me tell you why.

When Zastava was still located in the former country of Yugoslavia, they did a number of modifications to the base Soviet AK-47 design.  Relevant to this post whas their decision to use a retained grip nut that is riveted to the receiver.  This is different from AKMs that have a removable forged grip nut that drops down through a square hole between the trigger guard and the rear end of the receiver.

All AK-based rifle designs that I know of have this grip nut “strap” that is riveted in place.  Note how the trigger guard rides higher than a normal AKs and a longer rivet is used to pass through the trigger guard, strap and the receiver itself.

When it comes to grips, that strap and its rivets are the problems.  If you have a grip with very limited space in the top, it will not fit – at least not without modification.  The AK-12 grip has a tight backstrap that goes along the bottom of the receiver and I don’t think it could even be made to fit.

Notice the extra rivets sticking up behind the round grip screw hole.
This is our version of a Russian AK-12 grip.  It’s very comfortable and a grip I like a great deal.
The middle of the top and some of the back aren’t going to clear the grip nut strap and rivets.  I could carve/Dremel the middle out but there is very little material to work with in the back.  Might it work?  Maybe but I didn’t have time to give it serious try.

If you look at the top of a traditional Zastava black polymer grip, you’ll notice the top is wide open.  It has plenty of room to accomodate the grip strap.  So, a grip like a Russian Molot will work as well.

The Molot’s top is wide open.
Due to the wide open top, a Molot grip can readily go on a Zastava.

Summary

Grips with shallow tight tops will not fit on a Zastava rifle, unless modificatios are made.  Examples of grips like this are Hungarian AMDs, IMI Galils, Polish Beryl eronomically styled grips, and Russian AK-12s.

What will fit are grips with big top mouths such as many traditional AKMs (Romanian and Egyptian), plus newer grips like the Bulgarian ARMs, and Russian Molots.

I hope this helps.

Adding a RS Regulate GKR-9DY Handguard To A Zastava M77

Ok, so I planned to completely redo the M77 and keep the Battleworn wood for the future just in case. The first step was to swap out the wood handguards for a RS Regulate GKR-9DY. It’s a 9″ MLOK rail for Zastava AK-type rifles – this matters because a Zastava handguard is longer and a different shape than an AKM handguard.

Scot Hoskinson owns RS Regulate and is a meticulous engineer. His products are top notch and one thing I would tell you is to always read the instructions. He puts a lot of effort into documenting what you need to do so find the instructions and follow them.

Trust me – read and follow the instructions to install a RS Regulate handguard. Note the instruction sheet is for the old part number GKR-9Y. Scot revised the part number and it is now the GKR-9DY — same handguard but different part number.
Per the instructions in steps 3 and 4, I tapped the end cap into place. Note, you do need to test fit and make sure it will fit. You aren’t beating it into place with a ton of force. Mine went in without any filing needed but I did need to tap it to get it fully seated. You want the end cap to sit in the receiver firmly – not loose.

I don’t have photos of every step Scot lists, but I do want to mention step 5 – the front retainer set screws are backed out towards the receiver with the allen heads facing the rear. Once you have the front retainer in place and screwed to the handguard in step 10, you then tighten down the set screws to make everything nice and tight.

In all of his steps, be sure to follow the torque specifications and use blue loc-tite or your favorite medium strength thread locker. If you don’t, then the screws will risk coming loose and potentially falling out.
You can see the rifle’s handguard retainer is locked in place because the cam lever is rotated backwards. Looking down past the barrel you can see one of the two front retainer set screws waiting to be snugged down.
I used a long Bondhaus ball head allen key to reach in and tighten the set screws. Let me spare you some future grief – buy quality sets of allen wrenches that properly engage your fasteners. The cheap import keys are prone to poor fitment and/or rounding over the edges and both will mess up your fasteners.
I applied Blue Loc-Tite before I snugged down the set screws. I removed the residue with a shop towel.

The Gas Tube Cover

The RS Regulate handguards are the lower-half only. It’s up to you to decide if you want to run the wood or just what. In my case, I am using one of our Yugo/Zastava gas tube covers that is made from glass-fiber reinforced high-temp urethane. A Yugo gas tube cover is significantly longer than that of an AKM and are not interchangeable.

To remove it, rotate the locking lever on the rear sight base. Zastava is one of the makers that make that lever really tight. I use a large adjustable wrench’s jaws to hold the lever while I rotate it up. You can also use a hammer with plastic heads to tap the lever up. Once it is rotated, the rear of the tube closer to the receiver can be lifted up and the unit brought back just a tad to clear the front gas block. By the way, the bolt carrier must be removed or the long gas piston will be in the tube and block removal.

I didn’t get a picture of the gas tube with the wood before I removed it so we’ll just pick up here. This is one of our high-temp Yugo/Zastava gas tube covers. The spring clip is from the wood set and pops into the our cover to help provide tension and support. If you don’t have the clip, I would recommend buying one vs. skipping it. Check Apex Gun Parts, Robert RTG, Numrich, Centerfire, etc.
The spring clip just presses into the pocket molded foir it in the cover.
I like to use a vise to hold the forged end of the gas tube. DO NOT try and clamp the thing circular end or you will crush it. The vise you see has smooth jaws and will not hurt the forging – if your vise has aggressive jaws to hold material, use something to protect the gas tube like jaw covers, pieces of wood, etc. In this photo, the cover is fully rotated into position. You may find it easier to rotate your cover to the left or to the right when it comes to installation or removal. If it will not turn, carefully inspect why and remove a bit of material as needed with a file, Don’t rush – you want a firm fit and for it to look good.
What it looks like when done.

Years ago, I did do a blog post with more instructions and links to videos. Please click here if you want to read it.

End Result

Summary

RS Regulate makes some great lower handguards for a variety of AKs including for the Yugo/Zastava M70 and M77s. It takes a little bit of effort to install and is very much worth it. You can optionally use your wood gas tube cover or buy one of our polymer units.

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 Century Zastava PAP M77 in .308 – With Battleworn Furniture

Years ago, I had a Zastava M77 and regretfully sold it back in 2014. It was one of those situations where I had to sell it to fund other projects but I didn’t even get a chance to shoot it. I also had a custom M76 (the 8mm version) for a while but I did sell that one – mainly because it was a primer popper. That is a known issue because the firing pin hole opened up out of spec due to corrosive ammo use and didn’t adequately support the primer as a result but I digress.

I had resisted buying another one until Zastava decided to release what they called the “Battleworn” model (ZR77308W) and I caved. On one hand, it comes with some really nice retro looking Europen beech wood furniture. What really got me was that it was way cheaper than their other models that had optics and/or polymer furniture at that time.

Why the M77?

So, I had wanted to get back into the Zastava designated marksman’s rifle (DMR) game for a while and was just biding my time. The reason I wanted the M77 was due to all of the quality match 7.62×51 and match .308 match ammo that is out there. In comparison, try finding affordable true match grade 8mm ammo for the M76 or match 7.62x54r for the M91. You can find it once in a while but it’s not cheap and choices are limited here in the US. On the other hand, match 7.62×51 and .308 plentiful and affordable.

So, the main reasons were the ammo and the second was the M77 Battleworn model being very affordable in the Late Summer of 2023. As I am writing this, a quick search on GunBroker shows the Battleworn model selling fro $1369 with one 20-rd magazine up to $1,499 with five 20 round mags plus the various models are a lot closer in price. I paid less last summer but you get the idea. (In 2014 I bought a M77 with a thumbhole polymer stock and polymer handguard set for $600 or 700 from Centerfire Systems but that’s the way pricing goes – any vendor will raise prices to what they think the market will bear to try and maximize profits.)

Taking a Closer Look

It’s well packed in an egg foam box. Note the CSSpecs 25 round magazine on the box cover.
Honestly, the wood is really nice. It’s very reminiscent pf the M76 wood with a few minor exceptions – the grip does not have a ferrule, the recoil pad uses allen head screws and the stock bolt is one of their modern commerical shorter ones vs. the long Yugo military 8x1x260mm (about 10.23″ long).
Like many aspects of the original designs, the Yugoslavs modfield their scope rails and how they mount The result is more to the rear and is often refered to as “rear-biased” so they need a scope mount vs. an AKM pattern rail.
Honestly, the wood is cool. It has almost rough hewn look but better finished if that makes sense. The grip reminds me of one that Matt Shuster of Ironwood Designs came up with many years ago before he passed. I think he called it the “mini fat cap” – if someone remembers, please tell me. He made the M76 Fat cap patterned after the original wierd awkward really fat but oddly short M76 grip but without a ferrule. Then he came up with a far more elegant smaller one and this Zastava design reminds me of it. Folks, Matt helped me get started years ago and was a genius with wood. God rest his soul and take care of his family.
It has the mile long 19.7″ cold hammer forged barrel. The silver disc on the gas tube is the three position gas regulator. It has a slant brake on it and 14x1mm left hand threads under it just like any other AK. A M76’s long flash hider is actually part of the front sight assembly but that is not the case with the M77 – you can install whatever you want. Also, note the cleaning rod.
Here’s a view of the rifle looking at the operating side. The chromed bolt jumps right out in contrast.
The M77 uses a bulged trunnion and the oversized AK receiver needs to accomadte it. These bigger 1.5mm thick receivers are beefy. They both hold the various component assemblies in position and the thicker receiver means more steel to compensate for any metalurgical or hardening shortcomings.
Zooming in on just the receiver. Note the notched selector/safety lever and the relatively tall selector stop. In the top right you can see the other side of the operating rod lock.

Opening it up

The locking dust cover was introduced in the M70 Yugo rifles because their doctrine made extensive use of rifle grenades. They didn’t want the cover top pop off so they added a sliding lock that holds the rear recoild spring assembly in place and, thus, the top cover in place. By the way, one of the really nice side benefits is that when you reassemble a rifle with one of these locks, you put the recol spring in front, install the dust cover without fighting the spring, push the button and the recoil rod pops out the back.
Looking at the locking assembl, the plunger button the operator pushes is at the bottom of the photo. The slightly elevated portion under the top lip of the trunnion (top in this photo – right side in real life looking down – is what slides out of the way wehn pressed so the recoil spring assembly can come forward for removal. What you don’t see is the hidden compression spring. If you ever need these parts, CNC Warrior make and sells both the whole assembly.
Looking down at the classic double hook AK trigger and double wound spring. I’ve had guys ask me why did they double these? The answer is fault tolerance. The second hook is there if the first should fail and the second spring winding is there should one of the two fail. In all of my years working on civilian AKs, I’ve never seen a hook fail but I have seen springs fail although very, very rare and usually from a surplus kit build.
Look at those hooks! They are forged and not stamped. The bevels in the front and the back help the bolt carrier pass by.
Here’s a better view of the three position gas regulator disc. Note the vent holes in the gas block itself.
One oversized bolt assembly. Despite what some may tell you, the PSLs and these M76/M77/M91 families of rifles are oversized AKs. The SVD Dragunovs use very different bolt carrier assemblies.
Longer than a normal AK gas pistol and chrome plated to improve corrosion resistance.
View from the side. Some of the machining is crude but effective in places.
Bolt extended in the carrier.
I chuckled when I saw this. There are two numbering systems on some of the parts – crisp machined ones and ones done by hand with an electropencil like you would see on some kits.
You an see the numbers of the key parts and they should all match.
Interesting – more holes to vent propellant gasses.
A better view of the upper and lower handguard assembly,
A view of the grip.
The buttstock has the distinctive grip area like you would see on the M76 military stocks. I have never had the purpose of that grip area explained to me.
It uses a classic Yugo military sized recoil pad. What’s noteworthy is that they have ditched the old slotted screws for allen/head-head screws.

Summary

This gives you an overview of the M77 battleworn model right out of the box. Nothing really surprised me and the quality looked good. Sometimes I buy stuff and regret it but not this time.

If you know me, you also know I could not going to leave it alone and the customizations will be in future posts.

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.

Added Browne Works Wood Grips to My New RIA 52000 Big Rock

Back in May 2023, I posted how I put Browne Works wood grips on my 9mm RIA 51679 Tac Ultra. I was honest when I said I did not like wood Grips before I saw what Mark Browne produces and actually had them on a pistol.

In early March 2023, I picked up my second RIA 52000 Pro Ultra Match 6″ HC 10mm pistol – more affectionately known as “The Big Rock”, which is exactly what it is. I sold my first Big Rock many years ago because I needed the funds and regretted it once I started making custom 10mm mags for whole family of high-cap 10mm and .40 S&W RIA pistols. I couldn’t buy a new one at the time because Armscor, who owns RIA, only seems to make them periodically. Maybe 2-3 years later after I wished I had it and was looking, 52000s started popping up on my saved searches – Gunbroker alerted me first and I bought one about a week later. [A number of places have them now including GrabAGun – click here]

I should add that as soon as I ordered the pistol, the next thing I did was to order another set of grip panels from Mark Browne. His grips just look and feel great compared to the rather boring but durable G10 composite grip panels that come with the pistols.

Bottom left is the new Big Rock with its factory grip Panels. Above it and to the right is the 51679 with Mark’s wood panels. The lighting doesn’t do the wood justice.
Here is a better view of the wood on the 51679 plus you can always go to the blog post about it and see more.

The new panels for the Big Rock arrived

I emailed Mark and told him how much I liked the first set and he said he’d look for one with plenty of grain and contrast. What showed up was awesome.

…Wow…

Fitting them to the Big Rock

While RIA does use modern CNC machines to make the frames, the funnel fitment can vary – I know this based on clients that have fitment issues with the relatively shorter 9mm mags using Dawson Base Plates. Either they do not use a jig or it moves and wheter the funnel sits exactly can very. Why this matters is that you may find the panels go right on or you may need to fit them. DO NOT FORCE THEM! So let’s step through this.

Each OEM grip panel is held in place with two unique Allen head screws. Remove the screws and the panel lifts right off. Note in this photo how very little material is between the grip screws hole and the funnel – that’s tight.
The pistols are made in the Philippines and then need to travel across the Pacific. They liberally coat these pistols in preservative oil and this is one example of how much they use. Have a towel or rag handy to wipe this stuff off before you start installing the wood panels. By the way, this is typical of all the RIA 1911 pistols and again highlights why you need to clean them.
This side went right on without adjustments being needed. That was an unexpected pleasant surprise. They panels need to seat fully without pressure being needed. If you try to force them in, something will snap.
Everything is nice and flat and the screws went in without forcing them. The screws are installed until they are firm – not so tight the wood snaps – they just have to keep the grip panel in position, You do need to use a dab of medium-strength screw threadlocker such as Loc-Tite Blue to keep the screws from backing out.
The other side had issues. Teh funnel was riding high here and the panel would not even seat fully. To adjust the wood, take a single cut file and remove a bit of wood from the bottom and try over and over.
Fitting is slow work with wood. It is better to be able to take more off than wish you could put it back on. After maybe 5-10 minutes I thought I had the panel good to go but it was still riding too high and the screw could not seat properly. So, more fiiling and testing until it fit completely.
Take your time and you will get a nice fit without a gap. This is a great example of time, patience and handwork can generate a far better end result than being in a rush with a sander and taking off too much. The bottom is the new Big Rock.
The top is the new Big Rock with it’s 6″ barrel and slide. I really like the gloss finish. It really brings out the contrast in the wood.

Summary

I can’t stress it enough – I really like the grip panels from BrowneWorks. The quality, fit, feel, finish … they are all there. If you are even remotely considering new wood panels for your RIA A2 High Cap pistol, you really ought to check out their website. Look for the menu button in the top left of the screen, click on it and then look for Rock Island grips.

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.

Ammunition

Swiss P Defense BlackRound 9mm NATO 124 Grain 1,500 Rounds With Ammo Can

Folks, Palmetto State Armory (PSA) has an interesting Daily Deal going on right now. They have 1,500 rounds of Swiss P Defense Blackround 9mm NATO ammo. Two reasons you should care: First, this is the NATO load which is slightly hotter than 9mm Luger – SAAMI pressure for 9mm Luger is 35,000 PSI and Nato is 36,500 PSI with approximatly 1,1100 FPS for 115gr 9mm Luger and 1,250+ FPS for the 124gr 9mm NATO — It all means more energy. Second, the maker is Swiss P Defense of Switzerland who is truly a top notch ammo maker. If you are even considering picking up some 9mm ammo that will work good in a pistol, PCC or sub-gun, I’d recommend you check this out.

Israel

Videos: Three Good Documentaries on The History of the Israeli Uzi – 2024 Edition

1 Comment

2024 edition prologue: I had to revise my list of Uzi videos to reflect one that had been removed from Youtube and two that were added.

As part of my research into the iconic Israeli Uzi, I found these videos that do a very nice job providing background on the political climate driving the need for the Uzi.  For fans of the Uzi, these may give you some appreciation for the forces that shaped it.

The second video is a great one from Ian of Forgotten Weapons:
