Details:

The AB Arms nickel boron AR-15 bolt carrier is designed for AR-15s in 5.56 NATO, .223 Rem., and 300 Blackout. A state-of-the-art nickel boron coating is at the heart of the bolt carrier’s advanced design and provides for superior functioning.

Competition Grade

The nickel boron AR-15 bolt carrier is an M-16 style 8620 steel bolt carrier. It comes with a military-spec 4130 steel gas key. All Parts are nickel boron coated for increased protection and optimum performance. The boron coating not only protects the metal, but also imparts a natural lubricity that enables the bolt to operate more smoothly, requiring less frequent maintenance. The coating also significantly reduces fouling which translates into a shorter cleaning time.

Superior Craftsmanship

The AB Arms M-16 style nickel boron AR-15 bolt carrier is designed with greater mass that results in superior operation in both semi- and fully-automatic rifles. Furthermore, the entire assembly is built to exacting standards on high-tech Swiss machinery that results in producing components with the strictest tolerances and most superior finishes possible.

No Gunsmithing Required

The nickel boron AR-15 bolt carrier comes drop-in ready with the gas key and gas key screws already installed. Installation requires no special gunsmithing skills.
