This Bolt Carrier Group’s critical components are coated with an advanced QPQ process and finished with a REM Polish giving all the components a smooth, low friction surface. Our process not only helps with lubricity, but also adds in the adhesion of the QPQ giving your a more durable and reliable finish. Our BCG’s (Bolt Carrier Groups) are fully assembled, staked, and tested prior to shipment. Our complete Bolt is case hardened, shot peened and MPI (Magnetic Particle Inspection) tested to assure consistency.
NOTE: Please stay away from solvent based cleaners when maintaining your firearm and components.
