Odin Works ACC308BCG Bolt Carrier Group Black Nitride - AR-10

The Odin Works ACC308BCG Bolt Carrier Group is an AR-10/.308 platform BCG finished in low-friction Black Nitride (QPQ) for long-term corrosion resistance and slick cycling. It is built as a multi-caliber, high-pressure unit intended for .308 Winchester, 6.5 Creedmoor, 6mm Creedmoor, and any other cartridge sharing that case head size.

The carrier is machined from case-hardened 8620 steel and is paired with a properly staked 4130 steel gas key. The bolt is MPI (magnetic particle inspected) and HPT (high-pressure tested) at the factory, and Odin Works uses a firing pin retention pin in place of the typical cotter pin, a small but appreciated upgrade that simplifies field stripping.

Designed and made in the USA, the ACC308BCG drops into any standard AR-10 upper - a solid choice for a new build, a replacement, or an upgrade from a softer-finished mil-spec carrier.
