The Odin Works Enhanced 9mm Bolt Carrier Group in Black (Odin Works part no. ACC-9MM-ENHANCED-BCG-BLK) is a purpose-built bolt carrier group for 9mm AR-platform uppers, not a re-purposed 5.56 carrier. Odin Works engineers the Enhanced BCG specifically around the blowback operating system 9mm AR uppers use, which runs differently than a direct-impingement 5.56 gas gun. Running the correct dedicated 9mm carrier rather than an adapted rifle-caliber unit is what keeps a 9mm AR cycling reliably. It is finished in black for a straightforward match to most builds.
