Video: Russian Gunbusters Fires An AK-12 Until It Fails. Wow! Very interesting comments about 5.45 and 5.56 AK barrel Stresses

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!

Video: Russian Gunbusters Fires An AK-74M Until It Fails

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.

Video: Russian Gunbusters Fires a 1974 RPK in 7.62×39 Until It Fails – You Totally Need To Watch This!!

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 flame
Even 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.

Video: Russian Gunbusters Fires 1,400 Rounds Through A 7.62×39 AK-103 Trying to Get It To Fail

In this episode, Georgiy Gubich operates a 7.62×39 AK-103 built in 2019 on full auto trying to get it to fail. The AK-103 is a remarkable rifle as you will see in the video

He’s smelling hot plastic
Starting here forward he really needs to struggle to get the bolt to exit the chamber. It seems to return and cycle just fine when firing.
He’s seeing flame from the handguards
The lower handguard had already fallen off during a previous reload but look at the barrel glowing red.
The rifle survived through two spam cans, 1,400 rounds, of ammo!
After all that, it could still shoot 2 MOA at 100 meters. Definitely a remarkable rifle.

Watch the Video!

Summary

I’m a fan of both the 7.62×39 round and the AKs that shoot it so I was rooting for the rifle the whole time. It’s pretty amazing that it still ran after 1,400 rounds.

I hope you enjoyed this!

Ian McCollum Interviews Max Popenker Who Shares His Deep Knowledge On The History Surrounding the Design of the AK-47

I’m definitely a fan of the AK-47 rifle and am always looking for more insights about the history and design. Ian McCollum of Forgotten Weapons recently hosted Max Popenker, who is a Russian small arms researcher and publisher of Modern Firearms – one of the original firearm research websites. Between the two of them, there is a ton of knowledge.

The AK-47 design was the result of collaboration and competition amongst designers and didn’t happen magically overnight.

Now the video portion is ok but what is really cool is listening to Max unravel the history that led up to the AK-47 rifle’s design – the desire by the Soviets to develop a system of small arms, the influence of German small arms, and other Russian designs.

AK-203 Reliability Testing Video From Kalashnikov Media

Here’s an interesting but short video of Vladimir Onokoy, who is a Technical Advisor with Kalashnikov Media, showing the AK-203 undergoing environmental testing – freezing cold, desert sand, rain and a combination. Vladimir is speaking in Russian but there are subtitles and it’s not surprising that the AK-203 performs well.

Russian Spetsnaz 2018 – Training and Combat footage

This is an interesting video that is a collection of both training and combat footage. Absolute Production assembled it with some catcy music in 2018 and I noticed the date stamp on some of the drone footage was 2015.


The video provides a good opportunity to see weapons and tactics.
