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.
