This will be short post and not a very happy one from my perspective. A few days ago, I emailed Zastava USA for an update on their planned importation of the M91 rifle. They responded to me on June 4th and reported that they will have a “very limited number” some time this summer and the MSRP is $3,400. Wow. I had hoped it would be much more affordable than that – I’ll just have to stick with my M76 and M77 at that price point.
I had really hoped they would be more affordable but after my first post, a number of guys in the know said the price was going to be well over $2K depending on the options selected. Well, now I have the first hand info to pass along.
They did not respond about the M93 by the way. So, no updates on that front but given the pricing on the M91, I’m betting it will be high-priced as well.
Sorry I don’t have better news. For folks who can afford them, please post photos and your experiences so I can live vicariously.
They are here! The following are Zastava listings of weapons you can buy online and have shipped to your FFL:

I finally got a chance to take the Yugo M76 to the range and my youngest daughter went with me although now that she’s in college she’s gone a lot. I do have fun when she’s home as she loves shooting also and knows her way around a rifle.
We set up at 100 yards and I did the initial test firing and sighting in of the rifle. Function-wise, it was great. We did not have a single failure to feed or eject the whole day.
By the way, my daughter is wearing MPOW 035 ear muff hearing protectors and she said they worked great. She wore them when we were shooting the M76, my .338 Lapua and 9mm Glocks. They are excellent not to mention a good deal. I have three sets of them now for her and others. I am still using my Howard Leight by Honeywell electronic ear muffs.7
Both of us were wearing NoCry safety glasses. I use ones that go over my prescription eye glasses and my daughter wears normal ones because she has contacts.
One thing the slowed me up a bit was that the laser bore sight didn’t really help me out much. I have a new one from Wheeler that works great on the actual muzzle end of rifles but it would appear the M76’s brake was not truly perpendicular to the bore. Normally it is pretty slick but at the range, I had to fire a number of rounds to even get them on the backing board first and then finally to the bullseye.
We were shooting S&B 196 grain SPCE ammo. My groups were about 1.5-2″. I’ll get back down to the range one of these days with my better rest so I can test the accuracy. I have some Hornady Vintage Match ammo too that has cool specs but since I didn’t have my bench rest with me, I largely saved it for next time and will explain why I said that in a moment.
Pierced Primers
The only problem we encountered was the firing pin piercing primers. We went through almost 40 rounds and about a third had pierced primers. This is a known issue with M76s and, yes, the rifle is headspaced properly.
At first I thought it might just be the S&B ammo so I tested it with five rounds of Hornady Vintage match also. I think two of the five Hornady rounds were pierced. At any rate, here are some photos of the S&B ammo.
There are a lot of posts about the piercing and cratering of primers with the M76. I’m pretty busy right now but will read all that I can before I do anything.
First, I plan to confirm the pin protrudes between 1.42mm (.056″) minimum and 1.52mm (.060″) maximum.
Second, I want to compare how close the firing pin hole is to the firing pin on my other M76 bolt plus some of my AKs. I don’t think it looks unusually large but it should be investigated.
Third, I have a hypothesis – I think the firing pin needs more of a rounded radius. The current face of the firing pin is relatively flat. There were literally little punched pieces of primer laying on the firing bench that were flat and the primers that intact showed a very flat impact.
I’m not going to rush into anything. I do have a second complete bolt assembly that I can look at and scavenge from if need be. If you have suggestions, contact me – in**@ro*********.com.
Bottom line
We had a lot of fun. The rifle performed very well with no feed or ejection problems, no magazine problems and only the pierced primers were minor issue.
I definitely look forward to shooting this rifle with a better bench rest and also comparing it side by side with my .308 M77. Also, I’ll report back on what I try to correct the firing pin piercing or cratering primers at some point in the future. Until then, have a great day!

I’m new to the Yugo M76 rifle and the world of the 8mm Mauser cartridge. When I searched on 8mm Mauser all kinds nomenclature (how it is named) popped up and I had to do some research to understand what to buy. To try and help others I decided to write a blog post to try and clarify what type of ammunition you need to look at for the M76.
IS, JS, IRS & JRS Cartridge Types
When I heard my M76 was almost done being built by Two River Arms, I started shopping for ammo and quickly got confused – I’m good at that. I really didn’t want to deal with old corrosive ammo so my focus was on current commercial offerings and not hunting down old surplus ammo, etc.
First off, you will notice that much of the 8mm Mauser has an “IS” or “JS” designator after the size such as 8×57 IS. The “I” comes from the German word “Infanterie” which means infantry and was mistaken by some to be a “J” so some groups refer to the round using a “JS” designator instead.
When the round was first officially adopted in 1888, it was for 0.318 bore rifles. The “S” dates back to 1903-1905 when “S Patrone” or S ball cartridge was developed for use in S-bore rifles that was larger at 0.323″.
The nomenclature of the rounds can vary because of this and other factors so you are looking for: 8mm Mauser, 8×57 IS, 8×57 JS, 8×57 and so forth. It will likely say IS or JS somewhere especially if it is European but American producers may just say “8mm Mauser”.
Do NOT buy 8×57 IRS or 8×57 JRS. These refer to a rimmed variant that was developed for use in break barrel sporting rifles – double rifles, drilling rifles and so forth. Once in a while you will see it for sale and it will NOT work in a M76. Just remember – if it ends in RS, your day is going to Really Suck 🙂
CIP and SAMMI Specs
The standards body for small arms ammunition in Europe is the Commission internationale permanente pour l’épreuve des armes à feu portatives (“Permanent International Commission for the Proof of Small Arms”. They refer to the 7.92×57 Mauser formally as 8×57 IS.
The US standards body is the Sporting Arms and Ammunition Manufactuers’ Insitute (SAAMI) and they refer to the round both 8mm Mauser and 8x57mm.
I also noticed one interesting detail – the CIP designated rounds are up to 390.00 MPa or 56,565 PSI. Rifles that use the round must be proof tested to 125% of this.
SAAMI is considerably lower at 241.3 MPa or 35,000 PSI and is done is for liability reasons. Among other things, they are concerned that someone may put a modern cartridge in an older narrower throat “I-Series” barrel.
What am I shooting?
I really like Sellier & Bellot from the Czech Republic and they have a number of rounds for the 8mm Mauser listed as 7.92x57JS. The only load I can seem to find from them in the US is the 196 grain Soft Point Cutting Edge (SPCE) cartridge. It functions great and is accurate in my M76. I’m getting about 1.5-2″ at 100 yards with it.
I also have some of the Hornady Vintage Match but haven’t started using it yet. The specs Hornady publishes sure look good and I look forward to trying it.
Where To Learn More
The following websites provide a lot of insight into the 8mm Mauser round for those of you who want to learn more.
Thank you for reading and I hope this helps you find ammo for your M76.

The M76 is a pretty wicked designated marksman’s rifle capable of firing 1.5-2 minutes of angle with the hard hitting 8mm Mauser round. It does have a pretty bad weakness however – the magazines can jam so hard you need a tool to get the follower to come up. There’s a solution and that’s what this post is about.
So, What’s The Problem?
Zastava designed the M76 with a bolt hold open (BHO) follower. In other words, the follower has a big lobe that blocks the carrier from going forward and thus locks the action open. Sounds great, right? It would have been if they had closed the gap between the follower and the magazine body and/or made the skirt of the follower longer.
What happens way too frequently is that when the carrier cycles forward, it hits the bolt hold open lobe of the follower causing the follower’s nose to dive down and jam the follower. Literally, the end result most of the time is that it is a bear to open the action and get the magazine to release — I found I needed to fashion a dowel to hit the rear of the follower to free it up. Not good.
Some guys report more headaches than others and I can’t readily tell you why. Maybe Zastava realized the problem and corrected it or maybe there’s enough variation in the gap between the magazine body and follower that it does not always happen. I have about nine M76 magazines and they all nose dived when hit by the bolt carrier practically every time.
Cleaning The M76 Magazines
I should point out that I bought about a dozen M76 magazines – some from Apex and some from Ivan Drago on GunBroker. They all had a ton of old cosmoline on them and a lot if was on really thick. I pulled the old paper and junk off the eight you see below and left the rest in storage.
The Solution to M76 Magazines and Nosediving
Let’s start with two things that didn’t work just so you know. My first try was to simply polish all the edges. That did not work and neither did adding Dupont Teflon dry lube.
My second try was to use sand paper to round everything over underneath the lips of the body and the outside edge of the skirt. That did not work either – even with polishing and Dupont Teflon dry lube.
1. I went to OnlineMetals and bought a 12″x12″ sheet of cold roll mild steel – nothing fancy is needed. 12×12 turned out to be way more than I needed. Shipping is what kills you so I wanted to only buy one time even if some experimenting was needed.
2. I needed to figure out some basic template so I could cut out a bunch of tabs to to then try different shapes with by sanding them down. Now I have a big belt sander – you could use a file or whatever works for you.
Have you ever wondered about spot welders for casual use but thought they might be too expensive or too complicated? Actually, there are a lot of decent import models that will run on 120 volt household current. The thing you do is to buy one of the tong models, take a few scraps of sheet metal and get to know the sound and color when there is a good weld. First, do it and burn hole on purpose to see but don’t go longer than that or you will melt your copper spot welder tips. Next, back off the time and the amount the tons compress until you find a good weld that doesn’t pull apart easily. That’s it. Click here for a listing of tong spot welders on Amazon – be sure there are over 30 ratings and the higher the average score the better.
Bottom Line
Welding in the tab did the trick. I think it works for two big reasons – it closed up a rather large gap at the rear that allowed the follower to tilt down to begin with plus by making the skirt of the follower a bit longer, it could not tip as much either. I don’t think the exact shape of the bottom of the tab matters a great deal but you definitely must debur and polish each By adding a bit of Super Lube grease to the back, everything slid very smoothly. I am assuming it will not be needed as parts wear in and time will tell.
Also, I bought way too much 20 gauge sheet metal. You could get by with a far, far smaller sheet. I thought I would have to experiment more and it turned out to be simpler than I thought.
When I went to range feeding was great and not one problem with the follower nosediving when the carrier returned on an empty mag. Problem solved.

When I sent the M76 to Two Rivers Arms to build, I was still using Tapco G2 triggers in my AK builds. Since then, I have moved to ALG Defense’s AK Trigger Ultimate With Lightning Bow (AKT-UL) for anything I’ve built in the last two years. Folks, these are wicked triggers and absolutely hands down my favorite AK triggers.
Not only does the AKT-UL give you three compliance parts as it includes the hammer, trigger and disconnector but the feel is amazing. Now if you know how to tune a G2 trigger, you are used to having a fairly decent AK trigger. The AKT-UL units step it up a notch for sure. ALG does have a shorter and more crisp pull for sure plus they will tell you the trigger has about a 3.5 pound pull which you can tweak a bit by bending the hammer spring.
I got out my Lyman digital trigger gauge and did 20 pulls. The average was 3 pounds 13 ounces and the nice wide trigger shoe makes it feel less.
Installation Notes
Safety First Always – Make Sure Your Weapon Is Unloaded! Always assume a weapon is loaded until you confirm it is not. Keep ammo away from your work area and don’t test fit with live ammunition.
I really don’t have any surprises to report. It installed the same as any other AK fire control group and I didn’t need to use any pins and I certainly didn’t want a heavier pull so I didn’t use the auxiliary trigger spring either:
1. Install the hammer with the ears to the rear and spring around the back of the hammer. If it fights you during installation and the little legs that sit on the trigger are facing down, odds are you have the spring installed right. I lubricated all pins with Super Lube Grease before installation. That stuff is my favorite grease now.
2. Here’s a tip you will not see in the instructions. A trick I was taught years ago is to use a slave pin that will allow you to assemble the trigger, disconnector and its spring outside of the rifle. This makes it sooooo much easier!! What you do is cut a spare fire control pin or a piece of 5mm stock (0.1969″ or 13/64″ – cheap drill bits work great) down so it fits just inside the trigger pin hole from left to right and slightly taper the ends using a file or sandpaper. Trust me, if you don’t take a few minutes to do this, it is a heck of a juggling act to get the trigger in place with the pin pushed through while keeping the disconnector and its spring in place (don’t forget the little disconnector spring!!).
3. The trigger is installed by lowering it into position, pushing a fire control pin through the receiver and into the trigger carefully pushing the slave pin out the other side where you can grab it. Note, you will need to wiggle the trigger around some and I just do that with my right hand as I feel the pin through with my left.
4. Next, I used one of our fire control group retaining plates to secure the pins in place instead of the retaining wire. The wire is fine and you can use it if you prefer – I simply don’t care for them. Unlike some plates on the market, our plate is approximately 1.186mm thick and completely fills the groove of the pins to keep them from walking left or right and potentially falling out of the receiver.
You install the plate by inserting the nose groove into the hammer pin and then rotating the plate down so it secures the trigger pin as well. The rear hole of the plate, the only hole really,is where the selector/safety lever passes through and locks it into position.
That’s it for the trigger. Next up was the need to fix the magazines so they would not nose dive when empty and hit by the bolt carrier. That will be my next post.

I let the cat out of the bag a bit with my first post – I don’t like the Communist offset scopes. Yes, they are traditionally correct but I prefer a scope mounted on the centerline of the rifle with better optics including variable magnification. I had a combination in mind right from the start – the RS!Regulate mounting system and a Vortex Hog Hunter scope – why? Because I actually want to use this rifle to hunt hogs.
RS!Regulate Mount
Based on past projects, I knew that the best mounting system for my project would be the RS!Regulate system. The reason I am so adamant about this is that the design allows for a ton of flexibility in terms of front to back movement as well as left to right. Specifically, I chose the AK-303M lower rail and the AKR upper.
You basically install the AK-303M lower on the side rail. You can adjust the screw under the lever to adjust how much tension is applied when the lever is locked down.
My next step was to install the AKR top section and located it about three slots back as a starting point. In my case, that worked just fine. I then eyeballed the left to right location over the centerline of the rifle and installed the screws. Note, I do not drill and install the pins until test firing just in case I decide to move the rail around.
Vortex Crossfire II Hog Hunter Scope
Part of my design criteria for the rifle was to use it for hog hunting. That would entail using a scope that is pretty versatile in daylight as well as dusk. To accomplish this, you need a scope with a big objective to gather as much light as possible (50mm or better), a 30mm tube and good glass to aid in the transmission of the image.
In terms of the reticle, I really did not see a need for something really fancy with tons of MRAD or MOA markings for calculating distance, drop and windage. However, I did know that I would need some form of illumination for low light.
Lastly, in all candor, I knew I was putting an optic on a rifle that would likely shoot 1.5-2″ at 100 yards. I did not need to put a super-high end optic on the rifle – just one that was good enough and reliable.
After doing some reading, the ideal scope with the above design criteria and a very affordable price turned out to be the Vortex Optics Hog Hunter (SKU: CF2-31049). The specs are pretty good:
Magnification 3-12x
Reticle: V-Brite Illuminated (MOA) – The center 0.5 MOA Red Dot is illuminated and the subtensions are in MOA
Objective Lens Diameter 56 mm
Eye Relief 3.5 inches
Field of View 36.7-9.2 ft/100 yds
Tube Size 30 mm
Turret Style Capped
Adjustment Graduation 1/4 MOA
Travel Per Rotation 15 MOA
Max Elevation Adjustment 60 MOA
Max Windage Adjustment 60 MOA
Parallax Setting 10 yards to infinity
Length 14.3 inches
Weight 21.1 oz (just over 1.3 pounds)
Quick note on the lens caps. They are from Vortex but I am not super excited by that front one. They seem very well made but it is definitely a stretch to get the rubber over that huge front bell. I’m going to stick with them for now.
Figuring Out The Rings
In most cases, you want to mount the scope as close to the center of the bore as you can. This reduces the angle from the center of the scope to the center of the bore.
So here’s the tough part – any AK-type rifle has a big rear sight block (RSB) that is pinned to the barrel that not only holds the rear leaf sight but also holds the rear of the gas tube in position and the front of the dust cover is inserted into a slot — in short, it has to be here. Thus, any optic must clear the RSB somehow.
So this means we have two options – either the optic must slide into position and clear the RSB while doing so -or- we vertically lower the scope into position. To slide the scope in either means you go with tall enough rings and/or a small enough front objective that the front of the scope can clear.
The vertical option means we can use both a bigger objective and lower rings but begs the question – what do we do if we need to open the rifle up in the field? That is why I opt for quick release rings. Now, let me point out the photos show interim UTG rings that will not be on the rifle long term. I had them in storage from way back when and used them and some other models to do some “what if” scenarios.
The problem with this model of ring from UTG is that they use a round screw that goes through the Picatinny rail channel – they should be using square stock to securely and consistently secure the ring to the rail. While I do not expect a ton of recoil from the M76, I would rather the rings sit securely in the rail and not move around or place uneven stresses on the rails.
In the next few weeks, the UTG rings will be replaced by an American Defense AD-Recon-SL-30-STD one piece mount. American Defense makes top notch gear. The UTG rings definitely helped me prototype the layout and identify that I needed rings that measured from the base of the ring to the center line at least 0.915″. The AD-Recon-SL will hold to scope just a tad higher at 1.110″ and I am okay with that almost 0.195″ difference. It’s real tight right now as you can see:
Voodoo Cheek Pad
The one thing I quickly found out was that I needed a cheek piece to give me a better weld. I have used Voodoo Tactical cheekpieces a number of times in the past so I used one hear to give me about a 1/2″ lift to better line up behind the scope.
The Result
Right now, I’m happy. I need to get the ADM mount in and get to the range but everything is very promising so far.
Okay, in the next post, I’ll tell you about the ALG trigger.

In 1975, Zastava Arms was approached by the Yugoslavian military with a need for a designated marksman’s rifle (DMR) that was semi-automatic and fired a full power round. Rather than license the Dragunov design, Zastava took a similar path that the Romanians did with the PSL – they took the base Kalashnikov design and scaled it up to handle a full size rifle round that they already had. In the case of Zastava, they chambered the rifle in 7.92×57 (8mm Mauser round). This put the effective range for human sized targets out at about 800 meters (875 yards).
The M76 is an interesting beast. When you pick one up, the first things you notice are that it is both heavy and long. Zatastava opted for a stiff, albeit heavy, milled receiver and a heavy barrel profile. The published statistics for the rifle put the weight at 4.6kg (10.14 pounds) – definitely not light. The barrel is 550mm (21.65 inches) long and the overall length is 1,135mm (44.69 inches).
All Things Yugo
This is where I enter the pictured. In 2006, I saw a photo in Shotgun News of an 8mm AK and thought it was a mistake! Over the years, I both learned more about the extended family of firearms based on the Kalashnikov design, the more I came to really like the Yugoslavian branch of the AK tree. I also very much wanted to own a Yugo M76 but a combination of budget (or lack there of) and reports of quality control problems by commercial US builders held me back.
A few things all came together to get me to finally move on having an M76. First, I got to know Two Rivers Arms over the years both by selling grips to them as well as their building some M72B1s for me. I knew they would do exceptional work. Second, TortOrt released their 80% Yugo M76 receivers and Tim at Two Rivers told me he could work with one of them. Third, I was able to source a complete kit with no furniture but a Green Mountain barrel from Apex and bought a complete Yugo M76 kit from Ivan Drago on GunBroker that did not have the barrel or the optic.
I need to mention something here – I just am not a huge fan of the offset scopes that the Soviets and Communist Bloc (ComBloc) countries came up with. I prefer something low, centered and … modern (gasp). When I talked to Tim at Two Rivers about my plans to not go with the traditional ZRAK 4x optic he was surprised. I already knew I wanted to use one of RS!Regulate’s mounting systems because they are simply the best most adjustable mounts out there. My first thought was to replace the factory optic rail on the receiver with more on an AKM style but we found out that the RS!Regulate AK-303M would have enough adjustment that we could use the factory rail. So, I ordered in the AK-303M lower rail and the AKR upper – RS!Regulate mounts are two piece so you can really dial in what you want.
By the way, on the RS!Regulate parts, either buy them direct or from a reputable vendor – not eBay or Amazon. There are cheap Chinese knockoffs/counterfeits that are for sale and not only is the quality poor but you are taking money from the small business who put in the hard work and money to make these.
Eventually, all of the parts arrive, I packed them in boxes and sent them to Tim at Two Rivers. Then the waiting part happened. With top notch builders, they are backlogged with work. In my case, I asked them to put the project on hold at one point, so all said and done, it was just shy of two years before schedules aligned and the rifle was completed. When Tim called to tell me he was wrapping it up after test firing it, I was pretty excited to say the least.
Out of the Box Impressions
Tim sent the rifle to my friend and FFL, Scott Igert of Modern Antique Firearms and as soon as it arrived, I went over to get it. Scott and I pulled it out of the box. Wow , was it big and cool. The diameter of the barrel was actually surprisingly big.
When I got home, I measured it. The rifle was just under 44-3/4″ long from the tip of the compensator to the top of the recoil pad on the buttstock.
Weight of the rifle without a magazine was 9.86 pounds. It was 10.42 pounds with an empty magazine. I instantly liked the heft as I like heavy rifles and the balance was pretty good. Granted there is a mile of heavy steel in front of the receiver but it was pretty decent.
Here are some photos of the base rifle. You may notice the trigger is silver – I did install an ALG Ultimate trigger (my hands down favorite AK trigger now) before I took these shots and will write up some of the modifications in following posts.
I will be writing up my journey in upcoming posts and hope to take this rifle to the range in the near future. Definitely a big shout out to the gang at Two Rivers Arms for another wicked build! Thanks guys!

The Israeli Galil rifles have long fascinated me. As part of my journey, I do hope to build one so I keep my eye out for videos. While on Youtube the other day, I stumbled across this build video done by BFGMovies – Flandre Scarlets. For those of you who have not seen his work, he is a very talented young man who has posted some amazing videos on building AKs, how to convert a Tiger into a SVD and more.
In this video, Flandre steps you through a Galil build including how to install the bullet guide, barrel, extractor notch, gas tube, trigger guard and more. It’s top notch work and well worth watching.
