The Battle Arms Development M16 bolt carrier group (brand part no. BAD-BCG-M16) is a BCG built for hard use. Battle Arms Development machines the carrier from 8620 steel billet, case hardens it and finishes the parts in black nitride for wear resistance with minimal lubrication. The bolt is shot peened, CNC ground after heat treat and MPI/HPT tested, while a centerless-ground firing pin and a properly staked gas key finish the assembly. It carries the BAD logo laser engraved on the carrier.
