AK-50 Update - Firing Round #69

Published on July 19, 2021
Duration: 18:53

This guide details the testing and refinement process for the AK-50 V2 Prototype, as presented by lead designer Brandon Herrera. It covers initial test fires, identification of weld failures due to high forces, repairs, and subsequent magazine-fed testing. The video highlights critical engineering challenges, including component wear and the need for design modifications like helical lugs to enhance reliability. The roadmap towards the V3 prototype for a production-ready design is also outlined.

Quick Summary

The AK-50 V2 Prototype faced challenges including weld failure on the cam groove during test fire #69 and component wear like a broken firing pin retainer. Future iterations, like the V3 prototype, will incorporate helical lugs, inspired by the AKM design, to improve cycling reliability by reducing friction and stress on the bolt's locking mechanism.

Frequently Asked Questions

What were the main issues encountered during the AK-50 V2 Prototype testing?

During test fire #69, the AK-50 V2 Prototype experienced a weld failure on the cam groove due to high forces. Subsequent testing revealed a broken firing pin retainer and significant peening on the cam lug, indicating a need for design refinement and stronger components.

Why is the AK-50 project transitioning to helical lugs?

The transition to helical lugs, inspired by the AKM design, is intended to improve the AK-50's cycling reliability. This geometry allows the bolt to 'screw' into battery, reducing friction and stress on the cam lug and preventing premature rotation during the cycling stroke.

What are the planned improvements for the AK-50 V3 prototype?

The V3 prototype will incorporate helical lugs for enhanced reliability, refined aesthetics including a new dust cover and stock, and improved manufacturing tolerances. These changes aim to move the design closer to a production-ready firearm.

Who is leading the AK-50 project and what is their expertise?

Brandon Herrera is the lead designer and project manager for the AK-50. His expertise is evident through in-depth discussions on bolt carrier group geometry, weld analysis, and historical AK design principles, demonstrating high authority on the project.
