Why NP3 and Chrome?
The combination of NP3 (Nickel-Teflon) on the bolt and chrome plating on the carrier provides the ultimate balance of lubricity, corrosion resistance, and easy maintenance. These coatings dramatically reduce fouling and carbon buildup—keeping your rifle running clean even after extended firing sessions.
Designed for Suppressor Use
With its dual vent design, this BCG is ideal for use with suppressors or over-gassed systems. The venting helps direct excess gas out of the carrier, reducing blowback into the receiver and creating a smoother, cleaner shooting experience.
