Spike's Tactical is a US based AR manufacturer which creates high quality parts, uppers, and complete rifles. Every component is manufactured to Mil-spec standards and is backed by the Spikes Tactical lifetime warranty.

The Spike's Tactical Complete Bolt Carrier Group has the same MIL-SPEC specifications as their standard bolt carrier group but features the superior nickel boron finish. Nickel boron is a more durable finish and is easier to clean, eliminates friction and can run lube free for thousands of rounds. Additionally, the nickel boron BCG is High Pressure Tested (HPT) and Magnetic Particle Inspected (MPI) for even higher quality.
