The San Tan tactical Enhanced AR15 Bolt Carrier Group features a flared rear for reduced cant and tilt during recoil and increases reliability. Constructed from case hardened 8620 steel, the carrier has fewer points of contact, resulting in less friction. The Enhanced Bolt Carrier Group is ideal for suppressed use due to its increase of mass and dwell time. The 9310 case hardened steel bolt is machined to true Mil-Spec dimension and is heat treated after a precision fit.

BLACK NITRIDE FINISH: A process commonly referred to with SBN (Salt bath nitride) and sometimes QPQ (quench polish quench). All of these are a form of nitrocarburizing which is a chemical hardening of steel.
