Duration: 11:10

This guide details the construction and testing of the AK-50 prototype, a .50 BMG rifle developed by Brandon Herrera. It highlights the use of advanced manufacturing techniques like SolidWorks CAD and Haas CNC machining, alongside critical gunsmithing collaboration and rigorous testing to achieve a functional proof-of-concept. The process emphasizes engineering problem-solving to overcome challenges such as ejection issues.

Quick Summary

The AK-50 prototype, a .50 BMG rifle, was developed using SolidWorks for CAD design and a Haas VF6 CNC machine for precision steel component manufacturing. It features a gas-operated, long-stroke piston action and underwent heat treatment for durability. Ejection issues were resolved by modifying the bolt and ejector.

Frequently Asked Questions

What key software was used in the design of the AK-50 prototype?

The AK-50 prototype's components were meticulously designed using SolidWorks, a professional Computer-Aided Design (CAD) software. This allowed for precise 3D modeling of parts before they were sent for CNC machining.

What type of action does the AK-50 prototype utilize?

The AK-50 prototype features a gas-operated action with a long-stroke piston system. This design is known for its robustness and reliability, capable of handling the powerful .50 BMG cartridge.

How were the durability and strength of the AK-50's steel parts ensured?

Critical steel components of the AK-50 underwent a rigorous heat-treating process. This crucial step hardens the metal, significantly increasing its resistance to wear and the extreme pressures generated by .50 BMG ammunition.

What challenges were encountered during the AK-50's development and how were they resolved?

A significant challenge involved resolving ejection clearance issues. The team successfully addressed this by modifying the bolt and ejector design to ensure spent casings were reliably cleared from the action during cycling.
