This video reviews the KGM Universal Optics Rail for AK pattern rifles, developed for Ukraine to allow mounting of modern optics on existing Cnov pattern firearms. The rail attaches to the gas tube and uses the rear sight block as a locking surface. While initially skeptical, the presenter found the mount surprisingly stable for basic shooting, allowing for field stripping without removal. However, testing revealed that a significant drop onto the optic caused the mount to lose zero, and reinstallation did not fully restore it, indicating a potential durability concern under harsh conditions.

Quick Summary

The KGM Universal Optics Rail for AK pattern rifles mounts to the gas tube and uses the rear sight block for stability, allowing modern optics and grenade launchers to be fitted. While stable for basic use and enabling field stripping, testing revealed it can lose zero after a significant drop onto the optic, with reinstallation not fully correcting the issue.

Frequently Asked Questions

How does the KGM Universal Optics Rail attach to an AK rifle?

The KGM Universal Optics Rail mounts directly onto the AK's gas tube. It utilizes beveled clamping surfaces that engage with the sides of the rear sight block, providing a stable locking mechanism.

What is the primary benefit of the KGM Universal Optics Rail's design?

Its primary benefit is providing a Picatinny rail for modern optics on AK pattern rifles. A key design feature is its height, which allows for basic field stripping of the rifle without removing the optic mount.

Does the KGM Universal Optics Rail maintain compatibility with AK grenade launchers?

Yes, the KGM Universal Optics Rail is designed to be fully compatible with standard AK pattern under-barrel grenade launchers like the GP-25 and GP-30, as it does not interfere with the lower handguard.

What happens to the zero of the KGM Universal Optics Rail after a drop?

Testing showed that a significant drop of the rifle onto the optic caused the KGM rail to lose zero. Reinstalling the rail did not fully restore the original point of impact, indicating a potential durability concern for rough handling.
