Definitely lightweight by Jon, Verified Owner, February 16, 2020

Product Info for 2A Armament AR15 Titanium Regulated Bolt Carrier Group

The Titanium Regulated Bolt Carrier (RBC) is an ultra-lightweight carrier with a gas regulating gate built into the carrier itself. This provides a drop in, extremely lightweight solution for those looking to tune your AR-15s gas system and minimize felt recoil. 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.image

NOTE:

2A Armament recommends a slightly heavier buffer spring (Sprinco red tactical spring) and a lighter weight buffer (mil-spec buffer with weights removed) for best performance when using the AR15 Titanium RBC.

Does not support the use of forward assist. Not compatible with full auto systems. 2A recommends the use of milspec buffers and buffer springs.
