Wilson polished nitride BCG
Reviewed on May 4, 2026Verified with Build

Wilson Combats polished black nitride BCG has a mirror finish that cleans up easy with a rag. Gas key is staked from the factory. Bolt is shot peened and HPT/MPI tested. Beautiful piece thats also fully functional.

Wilson nitride BCG glossy
Reviewed on April 11, 2026Verified with Build

Wilson Combat nitride BCG is well made underneath but the finish is more glossy than the matte I expected from the photos. Function is excellent, properly staked gas key, HPT/MPI bolt. The polished look isn't for everyone but it cleans easy.
