In stock

SKU: DBW-BCG-009-SBN Category:

This AR9-style 9mm bolt carrier group is specifically designed for use in pistol caliber carbines. It features a ramped bolt, for compatibility with standard AR fire control groups. It is also fully compatible with both Colt and Glock-style lower receivers.

Black Nitride is a process commonly referred to as SBN (Salt bath nitride) and QPQ (quench polish quench). These are a form of nitrocarburizing or a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change which causes the hardening of steel. The chemical bath results in a deep dark black with a harder, more durable finish.
