Item # 10017 Style RMM-2A-LWBCG-A UPC 854361006184 Condition New Manufacturer [2A Armament](https://www.kygunco.com/brand/2a-armament) Weight 1 lb 2A Armament AR15 Regulated Lightweight Steel BCG The Regulated Bolt Carrier (RBC) is a lightweight carrier with a gas regulating gate built into the carrier itself. This provides a drop in, lightweight solution for those looking to tune your 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. The RBC can be tuned to most combinations of buffers, springs, suppressors, and barrel lengths. The RBC Is fully adjustable through the port door and does not require the firearm to be broken down for adjustment.

COMPATIBILITY NOTICE: Some 3rd party skeletonized upper receivers have the bore surface compromised that the bolt carrier slides on. 2A Armament does not recommend the use of these upper receivers due to a non-continuous slide surface that can cause binding and cycling related issues. 2A Armament cannot guarantee flawless fit and function in a 3rd party skeletonized upper receiver. ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
