Overview
The Battle Arms Development Standard Bolt Carrier Group (BCG) is a professional-grade component for the AR-15 platform. The carrier is machined from 8620 steel and finished with a black nitride coating, providing an ultra-hard, corrosion-resistant surface that requires minimal lubrication. The bolt is constructed from 9310 steel, which is shot-peened and CNC-ground to mil-spec dimensions following heat treatment. The BCG features a properly staked gas key made of 4130 steel with Grade 8 screws, an 8740 hard-chromed firing pin, and a 4340 steel cam pin. This assembly is designed to provide high reliability and longevity for hard-use carbines and duty rifles.
