The Bootleg Inc. 5.56 M16 Adjustable Bolt Carrier Group features a Mil-Spec design that is full auto rated and built to last. However, what sets this apart from standard Mil-Spec carriers is the 4 position gas adjustments built right into the side of the carrier that is easily accessible through the ejection port. Perfect for suppressed use and short barrel rifles, this allows you to easily tune your gas system to your set up and ammo. This adjustable BCG is machined from S7 tool steel and features a Lithium Isonite coating.
