Prototype Adjustable AK Gas System From Ukraine Part 2

Published on April 11, 2020
Duration: 21:56

This video details the installation and functionality of a patent-pending, adjustable gas system for AK-series rifles developed in Ukraine. The system converts the AK from a long-stroke to a short-stroke piston and features a user-friendly, external four-position adjustable gas valve. This allows for precise gas regulation, significantly reducing recoil, optimizing performance with suppressors and various ammunition types, and enhancing controllability, especially in full-auto fire. The design aims for soldier-proof operation and ease of field adjustment without tools.

Quick Summary

This Ukrainian-developed, patent-pending adjustable gas system for AK-47/AKM rifles converts the platform to a short-stroke piston with a four-position, tool-less external valve. It allows precise gas regulation for optimal performance with suppressors and various ammunition, significantly reducing recoil and enhancing controllability, especially in full-auto fire.

Frequently Asked Questions

What is the main advantage of the Ukrainian adjustable gas system for AKs?

The primary advantage is its user-friendly, external, four-position adjustable gas valve. This allows for tool-less, on-the-fly adjustments to optimize the rifle's performance with different ammunition types and suppressors, significantly reducing recoil and improving controllability.

How does the adjustable gas system modify the AK's operation?

It converts the AK's standard long-stroke piston system into a short-stroke piston system. This, combined with the adjustable gas valve, allows for precise control over the gas entering the system, preventing over-gassing and enhancing reliability and shooter comfort.

What are the four positions of the adjustable gas valve?

The four positions are: 1) Gas Cutoff (single shot), 2) Suppressed (reduced gas for suppressed use), 3) Normal (standard operation), and 4) Adverse (increased gas for underpowered ammo or dirty conditions).

Can this adjustable gas system be used with suppressors on an AK?

Yes, the system is specifically designed to enhance suppressor use. The 'Suppressed' setting (Position 2) significantly reduces gas blowback and recoil when a suppressor is attached, making the shooting experience much more pleasant and controllable.

What is the installation process for this adjustable gas system?

Installation involves replacing the standard AK operating rod with a shorter one provided with the kit. It may also require modifying the gas tube to fit correctly and ensuring the new operating rod is properly riveted in place.
