Blitzkrieg AR-15 Low-Friction Nickel Boron Bolt Carrier Group

The Blitzkrieg AR-15 Low-Friction Nickel Boron Bolt Carrier Group is a Full Auto, Nickel Boron plating Mil-Spec BCG designed for use with 5.56 NATO, .223 Remington, and .300 AAC Blackout ammunition.

Featuring our Low-Friction design, this BCG reduces friction in key points of contact with the upper receiver resulting in an impressively smooth cycling action. In addition to this design, this BCG features Nickel Boron plating. This slick material doesn’t just look pretty, it also allows for a lower friction coefficient which aids in smoother cycling of your weapon. Nickel Boron BCGs are easier to clean as well compared to their phosphate counterparts, and won’t retain nearly as much dirt.

Our BCG is constructed with mil-spec parts to ensure proper fitment and function, all parts are machined and are not manufactured with any MIM (Metal Injection Molding) processes.

Like all of our products, our Low-Friction Nickel Boron BCGs are made right here in the USA.
