Spike's Tactical M16 Bolt Carrier Group LW – AR-15/M16

The Spike's Tactical M16 Bolt Carrier Group LW is a mil-spec full-auto profile carrier designed for AR-15 and M16 pattern rifles. The full-auto carrier provides increased mass for reliable cycling with a wider range of ammunition and suppressor use, even in semi-auto-only firearms. This lightweight variant reduces reciprocating mass compared to standard BCGs, potentially improving felt recoil and cycling speed while maintaining durability for high round counts.

Machined from 8620 steel with a carpenter 158 steel bolt, this BCG features a phosphate finish for corrosion resistance and proper lubricity. The gas key is properly staked per mil-spec standards. Installation is drop-in for any mil-spec AR-15 upper receiver—no fitting or gunsmithing required. Includes bolt, carrier, cam pin, and firing pin.
