Spike’s Tactical Bolt Carrier Group- Lightweight Nickel Boron

SKU: 855319005518 Manufactured by: Spikes Tactical



Spike’s Tactical is a US based AR manufacturer which creates some of the worlds finest and highest quality parts, uppers, and complete rifles on the planet. Every component is manufactured to Mil-spec standards and is backed by the Spikes Tactical lifetime warranty.

This is the same Mil-spec BCG that Spikes Tactical sells, except it is coated with the most durable finish on the market, nickel boron. Smoother and harder than hard chrome, it allows this bolt carrier group to be run almost lube free for thousands of rounds. It is being adapted by the US military and many government agencies as a standard for their BCGs.
