Toolcraft Black Nitride .308 Bolt Carrier Group | BCG

Toolcraft uses the QPQ (Quench Polish Quench) process to augment the standard Nu-Tride process with the advanced Black Nitriding process. It enhances corrosion resistance due to the expanded secondary polishing procedure, followed by re-oxidation to produce a lustrous black finish as well as case hardening the steel.
