The bolt carrier group is without a doubt the hardest working component of an AR15. It is responsible for guiding the firing pin to the primer, extracting and ejecting the fired case, feeding the new cartridge into the chamber and, locking properly into the barrel extension. All these tasks benefit from proper lubrication. This Nickel Boron BCG has an advanced metal finish that offers high resistance to wear and corrosion as well as having an ultra-low co-efficient of friction, resulting in smoother cycling and less required lubrication. Due to this slick surface finish clean up is easier and faster than a standard bolt carrier group. With its strong finish even under high volume fire rates or while running a pistol set-up this bolt carrier group won’t let you down.
