2A-Armament LLC introduced its Regulated Bolt Carrier (RBC). This is a lightweight carrier with a gas regulating gate built into the carrier itself to provide a drop in, lightweight solution for those looking to tune their AR-15’s gas system. It eliminates the need for adjustable gas blocks and allows the firearm to be restored to a factory full weight system by simply swapping your full-mass carrier back into your firearm. The RBC has infinite adjustment from fully open, to fully closed on the regulating gate and can be tuned to almost any combination of buffers, springs, suppressors, loads, etc. Best of all, it’s adjustable through the port door!
