Spike’s Tactical M16 Mil-Spec Bolt Carrier Group Features:

The heart of any AR-15 rifle, and the key to assuring reliability is a high quality bolt carrier group. This mil-spec M16 BCG from Spike’s Tactical features all the components and specifications that make it a great addition to your next AR build, or as an upgrade from inferior commercial components. This BCG features a 8620 tool steel carrier, 158 Carpenter steel bolt that is shot peened, High Pressure and Magnetic Particle tested to eliminate many of the causes of premature failure. This commitment to reliability continues with the tool steel extractor with black extractor insert and Viton o-ring for consistent extraction no matter the ammo. The gas key is also a tool steel component and is installed with grade 8 hardware to resist shearing and improve longevity. The interior of the key is chromed to prevent carbon buildup and make it easier to clean, and most importantly the key is properly staked to prevent loosening. This BCG also features a phosphate finish, and is laser engraved with the Spike’s Tactical logo on the forward portion of the carrier.
