AK-50 Update - Firing Round #69

Published on July 19, 2021
Duration: 18:53

This AK-50 update details the testing of the V2 prototype, focusing on a redesigned bolt with a new cam lug. Despite initial weld failures on round #69 due to high forces, subsequent repairs allowed for successful magazine feeding. Night testing revealed component wear, including a broken firing pin retainer and peening on the cam lug. Future designs will incorporate helical lugs for improved reliability and reduced friction, with the V3 prototype planned to refine aesthetics and manufacturing tolerances.

Quick Summary

The AK-50 V2 prototype experienced weld failure on its cam lug during test fire #69 due to .50 BMG forces. After repairs, magazine feeding was successful. Future V3 prototypes will feature helical lugs inspired by the AKM design to enhance reliability and reduce friction.

Frequently Asked Questions

What was the main issue encountered during test fire round #69 of the AK-50 V2 prototype?

During test fire round #69, the weld holding the redesigned cam groove onto the bolt carrier group cracked. This failure occurred due to the immense forces generated by the .50 BMG round, highlighting the need for stronger attachment methods.

What design change is planned for future AK-50 prototypes based on recent testing?

Future AK-50 prototypes, starting with the V3, will incorporate helical lugs. This design, similar to the standard AKM, aims to improve reliability by allowing the bolt to 'screw' into battery, reducing friction on the cam lug.

What components showed significant wear during the AK-50's night testing session?

Night testing revealed wear on several components. Notably, a firing pin retainer broke, and significant peening and wear were observed on the cam lug, indicating that the current geometry requires refinement for durability.

What milestone was achieved after repairing the V2 prototype's bolt?

After repairing the cracked weld on the V2 bolt, the team successfully conducted magazine-fed testing. They achieved a significant milestone by firing a successful five-round burst, demonstrating improved feeding reliability.
