Details:

AB Arms offers their Nickel Boron Bolt Carrier Group for the AR-15 user who demands excellence from every component of their rifle.

The bolt carrier group is machined from the toughest steel and topped off with an impenetrable layer of nickel boron. This coating offers unfaltering protection from wear and corrosion that would ordinarily degrade a BCG over years of heavy use. The coating is also uniquely resistant to fouling, dramatically reducing the amount of time you'll spend cleaning the bolt carrier group after a long day on duty or at the range. This coating is built to last and will not wear off, flake away, or degrade even under the most constant use.
