Spike’s Tactical M16 Auto Nickel Boron Bolt Carrier Group Features
This Spike’s Tactical complete bolt carrier group is magnetic particle inspected and high-pressure tested, with an 8620 steel carrier and a Carpenter 158 steel bolt for demanding use. Every surface — cam pin, gas key, bolt assembly, and carrier — is nickel boron coated for a hard, slick finish that reduces cycling friction and wipes clean easily during maintenance. Compare it to our reduced-mass Spike’s Tactical Low Mass M16 Nickel Boron BCG, or browse our full selection of AR-15 bolt carrier groups.
