A recurring question I get is if a Bulgarian ARM-9 grip can be used on an IMI Galil rifle. Not easily is my answer and I took a bunch of photos so you can decide for yourself. You would need to add black epoxy to the inside back of the ARM in order to Dremel or mill it open further to duplicate the swing of the Galil’s lever – at least that’s how it looks to me because I don’t own an IMI Galil to experiment with.
So, here are some photos so you can see what I mean:
Note the difference in the shape of the ARM-9 grip’s notch on the left vs. the IMI Galil’s notch on the right
Here are the notches even closer.
Here’s the ARM sitting on top of the Galil for another perspective.
Here’s where you can see that the ARM-9’s original wall design is hollow behind the notch. It’s not an impossible change – if you were to abrasive blast the inside of the ARM grip and then use wax stripper, you could then fill that back in with black epoxy. It wouldn’t be an exact color match by any means.
Summary
So there you have it. They are different and definitely not a simple swap with out doing some epoxy work and then maybe a top coat of some finish if you want the colors to match. I hope this helps you out as you think through your options.

A fellow messaged me the other day and asked what options he had to replace the light fixed stock on his SDS 12 gauge shotgun. I told him that he has a lot. The rear of an SDS is very similar to an AKM or AK-74.
The rear piece that holds the stock in is called a “trunnion” they are what provide the real strength in the sheet metal receiver. The stock is held in place by the two screws you see. Be sure to use a blade screw driver bit that completely fills the slot. You can see that whomever installed the screws at the factor did not do this and slightly deformed both slots by using an undersized screwdriver or blade bit.You may need to use a wood dowel, or whatever you have handy, to tap the stock out. I like using a hardwood dowel because it doesn’t bend or scratch things all up.I used a Rifle Dynamics adapter that lets you convert from the AK-rear to an AR/M4 buffer tube. Both the Rifle Dynamics adapter and the one sold by PSA are very well made.
With the rear stock removed, you can use any AKM/AK-74 traditional wood or polymer stock that you want or adapter to use an AR-style stock. Read up online before you buy because there are tons and tons of options and combinations for you.
I hope this helps you out and here are a few examples for your consideration:

The typical semi-auto AK trigger has four parts – the trigger body, disconnector, disconnector spring and pin. Installing it can be a challenge because you need to properly align the disconnector while sliding the pin through from one side of the receiver to another. For me, with big hands, this task takes more effort than I want.
This is your typical semi-automatic AK trigger group. On the left is the trigger body, top right is the disconnector, under the disconnector is its spring and at the bottom right is the trigger pin. The challenge is getting this all assembled inside of the AK receiver as the pin needs to pass from one side of the receiver, through one side of the trigger, through the disconnector to capture it, out the other side of the trigger and finally out the other side of the receiver. Trying to get it all to align inside of the trigger takes some patience.
The Solution – Use A Slave Pin
There is an easier approach. We can slide a properly sized dowel pin to serve as a “slave pin” during assembly to secure and properly align the disconnector and trigger outside of the receiver. This simplifies life tremendously. The unit is assembled outside where you can see what is going on, is lowered into the receiver and then the actual trigger pin is pushed through and it displaces the slave pin – the slave just exits the other side of the receiver.
This is the slave pin. Note how one side is beveled more than the other. That is the side that is inserted first. The bevel helps move things around during insertion and then the 5mm body provides the actual alignment for the trigger pin.This is the assembled trigger group with the slave pin holding it all together.Normally this would be in the receiver but I want you to see what is going on. As the trigger pin is inserted, it pushes the slave pin out of the way and it exits via the opposite receiver hole.This photo shows how when the trigger pin is fully inserted, the slave simply drops out.This is an ALG semi-auto trigger and you can see how slave pin is exiting the receiver as the trigger pin is installed. So there’s the end result. A slave pin makes a world of difference. Note, that is one if our fire control group plates retaining the trigger and hammer pins.
If you’re like me and want an easier way to install AK triggers, these new slave pins are the way to go!

Well folks, we finally had a chance to go to the range for the first time this year. It was a beautiful day and the only shortcoming was that we had a number of rifles and pistols to test and not enough time to shoot a ton of rounds through each. To be honest, we had a blast 🙂
Palmetto State Armory (PSA) has a stunning array of Kalashnikov firearms now. AK-47s, AK74s, 100 series, rifles, pistols … it’s impressive. Click here to go to their main AK menu.
We were shooting 124 grain 7.62×39 FMJ ammo by Golden Tiger. This is great ammo and my favorite to use. For AK bulk ammo, it’s relatively accurate, reliable and consistent — notice that I say relatively. It will hold its own with any of the bulk steel case ammo or even do better. I’m not comparing it to hand loads or specialty ammo.
Niko is a heck of a shot and is familiar with AKs as well. He had to do Slavic Squat shot 🙂
I wish I could tell you that we shot hundreds of rounds but there just wasn’t time. We shot three mags through it – 90 rounds and did not have one problem. Yeah, it’s not many rounds but I figured some of you would like an update and I’ll post again after the next range trip.
Observations:
The little Vortex Crossfire did a great job and we had fun punching paper. The scope and the RS!Regulate optic mount worked out just fine. I’ve used the combo before and expected such.
The rifle functioned just fine with no feed or ejection problems
The rounds were grouping pretty well – we were not shooting for accuracy – more for function testing
The trigger was very nice – ALGs are great in general and what I like to use these days.
The brake did a decent job. I think a JMAC RRD-4C brake would have reduced recoil further but out of the box the recoil was not bad at all. When you think about it, even an AK with no brake is surprisingly pleasant to shoot during semi-auto fire
I definitely liked the feel – the weight and balance – of the rifle – the RS!Regulate handguard, our AK-12 grip and a Magpul ACS stock worked very well together
Me with my favorite AK shooting shirt 🙂
When we were done, I did take the rifle apart and did not see anything concerning. So, I definitely want to shoot it more and the rifle is off to a good start.

You know, it’s interesting how people will argue over stuff on the Internet. Give them a picture of a stick and they will argue about it! Now, turn the topic to AK rifles and debating what is the right or wrong way to do something, things get colorful fast and a lot of energy is wasted over trivial points.
In this video, Vladimir Onokoy, who always does a great job, goes over different reloading approaches. Now most folks do not know Vladimir but I will tell you he is the real deal with considerable Russian military experience and armorer-level experience with the AK platform. In short, I would recommend you listen real close to what he says plus bear in mind that this is a Kalashnikov Media video and they know their stuff as well 🙂
Watch the Video
Normally I give some screen shots and make some color commentary but this video is only 3:05 seconds and seeing is believing.
I fully agree with his conclusion – train and become proficient. They all work the question is what works best for you and only training and experience can answer that.

In this episode, Georgiy Gubich operates a 5.45×39 AK-12 on full auto until it fails. You’ll notice he is wearing body armor and for good reason as you’ll learn from the video.
He starts by loading up a case of 7N6 ammo into 30 mags and then dumping one after another. You get views from several angles and a shot counter plus his observations during the process.
The handguards are starting to smoke and Georgiy mentions he smells burning plastic.Note the barrel and brake care glowing red at 503 rounds. It’s hard to say for sure, but this puts the temperature at 930-1175F (500-635C) degrees. I don’t know if it is the camera lens distortion but the brake looks like it is drooping. In later photos it does not so I’m thinking the wide angle lens might be causing distortion.The handguard is on fire by round 510. It’s hard to say for sure but the temperature might be closer to 1490F (810C). She is hot!! Depending on the polymer they are using for the handguards, the ignition flash point could be from 572-1292F (00-700C). I would guess they are using something good because we can see the barrel is well past 1000F and there is an air gap plus the thermal mass of the handguard to consider which is why it took a while to reach the heat of ignition.Round 630 – Wow! That is an impressive photo. The handguard is on fire and by luck the camera caught one hell of a muzzle flash. I can’t help but wonder what the temperature of the barrel is under the handguards at this point. The barrel is started to rupture just prior to this point. Sparks could well be burning powder and there is definitely shrapnel flying as well. Yeah, right about now the body armor, gloves and face shield are making a lot of sense!Georgiy inspects the rifle and sees the burst barrel.This is where the barrel ruptured and it looks like it took out part of the gas block. Georgiy mentioned this is a common failure areas for 5.56 and 5.45 rifles due to the heat and pressure compare to larger calibers (I assume is he is referring to 7.62×39 and x51 variants). The rust you see is “flash rust” caused by the heat and being cooled down by water.It definitely took a beating.
Time for the Video!
Summary
The rifle held up three times as long as the Russian Ministry of Defense 180-round burst requirement. Practically, you would expect pauses during firing to allow it to cool down some. I thought his comments about the high-pressure 5.56 x 5.45 rounds causing significant stresses on the barrel was very interesting and hope you enjoyed this video as well.
By the way, a big shout out to Kalashnikov Concern for making these videos available. They are very good!

In this episode, Georgiy Gubich operates a 5.45×39 AK-74M built in 2014 on full auto until it fails. You’ll notice he is wearing body armor and for good reason as you’ll learn from the video.
As with his other videos, you definitely want to watch it to hear his observations during the testing and the post mortem review afterwards.
Georgiy is 210 rounds and gives us a great quote “The smell isn’t great”!!480 rounds into the test he can hear the plastic hissing as the bolt carrier is starting to stick when he is reloading. The plastic is still holding its shape.When he went ,to reload after round 570, he had so slam the rifle on the ground to get it to cycle. I’ve heard of this but it’s my first time seeing someone really do it and does it smoothly.Round 587 – the barrel ruptured just in front of the lower handguard retainer. Note, the Russian Ministry of Defense requires the weapon to handle a 180-round burst so they passed that test more than three times over.Here’s the rupture. Note the cooked plastic.Now this fascinates me. They are using a polyamide plastic and it held up remarably well. The solid parts closest to the barrel and gas tube were definitely decomposing but you will notice the horizontal ribbing was able to dissapate the heat fast enough to that point to retain its shape and structural integrity. That pattern makes even more sense to me now after seeing this.
Watch the Video!
Summary
Definitely a cool video and I appreciate Kalashnikov Concern making it possible. Georgiy rocks and really like how he changes mags and cycles the action not to mention his running observations during and after the test.
The biggest take-away for me by far is the understanding of why they ribbed the lower handguards – enabling the ribs to cool enough to maintain structural integrity is fascinating. In theory there will be a upper round-count limit causing more heat than can be dissipated but under practical use, they ought to hold up great.
I hope you found it interesting as well.

Ever wonder how long a heavy duty 1974 Russian RPK in 7.62×39 can fire almost non-stop until failure? Now’s your chance. This video features Georgiy Gubich firing in an episode of the Russian series Gunbusters firing an RPK as fast as he can doing drum and mag dumps on full auto. Yes, he’s wearing armor because he literally shoots it while it starts to burn an ultimately fails.
That is a ton of ammo and a RPK I would much rather own than see them fry it.Somewhere near 500 rounds being dumped from 75 round mags the handguards are starting to smoke.About round 997 or 998 the handguard bursts into flameEven though the handguard were on fire, he shot it until the barrel burst at round 1232.For me, it’s fascinating that the only thing that truly failed were the handguards and barrel. Everything else could still be used if the barrel was pressed out and replaced.
So you need to watch the video!!
Summary
You might be surprised by the seemingly fast failure of the rifle. Near the end Georgiy takes the RPK apart, notes what happened and points out that the problem for the rifle was the intense heat of the 75 round drums being dumped one after another. Normally you would fire a 2-1/2 30 round magazines and the pause in firing during reloads gives the barrel a chance to cool down plus practical applications aren’t going to see that type of sustained firing. One would assume that if all he had were drums that the RPK would have failed even sooner than round 1,232.
This was really a fascinating video to watch. Part of me really wants to bring that poor abused RPK home and repair it and part of me was interesting to see a video detailing testing to failure with this level of detail. A big thank you to Kalashnikov Group for helping put this video together.
