Brandon Herrera details significant improvements to the AK-50 prototype, focusing on a new double recoil spring assembly designed to enhance reliability. While live fire testing showed progress, cycling and ejection issues persist, particularly with standard ammunition. Further adjustments to the gas system and ejection geometry are planned.

Quick Summary

The AK-50 project features a new 'double spring' recoil assembly for increased force, aiming to improve cycling reliability. Live fire tests showed progress but persistent cycling and ejection issues, necessitating further adjustments to the gas system and ejection geometry.

Frequently Asked Questions

What is the main improvement made to the AK-50 in this video?

The primary fix involves a new recoil spring assembly. It uses a 'double spring' design (a spring inside a spring) to increase spring force within the limited space of the AK receiver, aiming for more reliable cycling.

What issues were encountered during the AK-50's live fire testing?

Testing revealed cycling issues and inconsistent ejection with standard .50 BMG ammunition. Even with hotter surplus API rounds, ejection geometry problems persisted, causing brass to interfere with the rifle's operation.

What is the technical rationale behind the AK-50's new recoil spring?

The double spring system is designed to provide more force on the bolt's return stroke. This aims to ensure reliable feeding and cycling, particularly when the rifle is fired at upward angles, similar to buffer systems in other firearms.

What are the next steps for the AK-50 project?

Brandon Herrera plans to continue refining the rifle. Key areas for future work include further adjustments to the gas system and modifications to the ejection geometry to resolve the remaining operational issues.
