Q LLC AR-15 Two-Piece BCG Stainless Steel Black Nitride 5.56x45mm

Description

This two-piece bolt carrier group from Q LLC is engineered for the AR-15 platform using modern materials and manufacturing methods. The design separates the front-end and rear-end to allow focused material selection: a maraging stainless front dressed in black with a nitride coating and a heat-treated stainless rear. The front end is SCAR-cut to help reduce bolt bounce, and the assembly ships with mil-spec gas key staking and mil-spec bolt, cam pin, and firing pin. The rear section is designed to retain the firing pin without a separate retaining pin, and the carrier is retained with a single pin for simplified field stripping.
