Why a Dual Ejector BCG Matters

Traditional AR15 bolts use a single ejector. The dual ejector design in the K-SPEC BCG delivers cleaner, more consistent ejection patterns and helps reduce malfunctions under suppressed conditions or during rapid fire. It’s built with Mil-Spec ejectors and springs, so no proprietary parts are required.

The Benefits of FDE PVD Coating

The FDE PVD (Physical Vapor Deposition) finish combines toughness and corrosion resistance with a unique flat dark earth color. This coating resists wear, reduces friction, and gives your rifle’s internals a premium look while improving function and durability.

Optimized for Suppressed Shooting

The K-SPEC BCG includes down vent gas ports that direct gases away from the shooter’s face, minimizing blowback when running suppressed. Combined with sand cut rails, it stays cleaner and more reliable, even in heavy fouling environments.
