This full-auto profile bolt carrier group features proper geometry and staking to ensure consistent performance in carbine and mid-length gas systems. The M16 profile carrier provides additional mass for improved reliability with suppressed or short-barreled uppers.\u003c\/p\u003e\u003cp\u003eFinished in black nitride for corrosion resistance and reduced friction, this BCG requires less lubrication than phosphate-coated alternatives.
