The Odin Works Low Mass Bolt Carrier Group (brand part no. ACC223BCGLM) is a .223-caliber BCG machined from steel and finished in black nitride, built as a reduced-mass carrier for the AR-15 platform. Odin Works cuts the carrier’s mass down from a standard BCG to speed up cycling and reduce felt recoil impulse, a common upgrade for competition and lightweight-build shooters. It is a straightforward swap for AR-15 owners who want a livelier-cycling carrier without changing calibers.
