Test Firing an AK (With No Rivets??)

Published on February 4, 2020
Duration: 10:20

This video details a dangerous experiment testing an AK-47 front trunnion without rivets, relying solely on receiver dimples. While dimpling creates a mechanical lock, the experiment ultimately fails catastrophically, demonstrating rivets are essential for structural integrity. The video also provides insights into AK construction and teases an AK-50 update.

Quick Summary

Building an AK-47 without rivets is dangerous. While receiver dimpling creates a mechanical lock, it's insufficient for structural integrity. The experiment showed the trunnion walking out, causing catastrophic failure and disassembly during firing, proving rivets are essential.

Frequently Asked Questions

What happens when you test fire an AK-47 without rivets?

Testing an AK-47 without rivets, relying only on receiver dimples, can hold for a few shots but will eventually fail catastrophically. The front trunnion can 'walk' out of the receiver, causing the magazine to drop and the rifle to disassemble itself during firing.

How does dimpling work in AK construction?

Dimpling the receiver into the countersunk holes of the front trunnion increases the surface contact area. This enhances the mechanical bond that rivets create, contributing to the overall strength and rigidity of the receiver assembly.

Is it safe to build an AK without rivets?

No, it is extremely dangerous and unsafe to build or fire an AK-47 without rivets. While dimpling provides some mechanical lock, rivets are essential for maintaining the structural integrity of the receiver and trunnion under firing stress.

What caused the AK-47 to disassemble during the rivetless test?

The catastrophic failure occurred because the front trunnion, held only by receiver dimples, began to 'walk' forward under recoil. This movement dislodged the magazine and caused the rifle to effectively disassemble itself while being fired.
