The Midwest Industries Nitride Lightweight 16-Inch Upper Receiver Group is chambered in .223 Wylde and fitted with a 14-inch Combat Series M-LOK handguard (part no. MI-N16CRM14-U). The 16-inch lightweight barrel has a Melonite finish and a 1/8 twist, and the upper is forged 7075 T6 aluminum with hard coat anodizing. A mid-length direct impingement gas system runs it, and the muzzle is threaded 1/2×28 with a Midwest A2 flash hider fitted.
