The MK10 lower accepts Glock-pattern 10mm magazines and is marked with the BANSHEE and MK10 rollmarks, along with CMMG Inc, Boonville, MO, USA. Capacity is stated at 15+1. An 8-inch barrel is clearly marked 10mm and is threaded, with a multi-prong/crowned muzzle device installed.
The action is semi-automatic with CMMG’s radial-delayed blowback system. Controls include an ambidextrous safety and an ambidextrous charging handle with large latches and a CMMG logo. A CMMG-branded textured pistol grip provides a secure hold.
The free-float M-LOK aluminum handguard features M-LOK slots and a short Picatinny rail section at the front. The upper is a flat-top design with a continuous Picatinny rail and an ejection port cover.
At the rear, the receiver extension is marked FASTBACK and wears an SB Tactical telescoping stabilizing brace for compact handling. Overall fit and finish reflect a U.S.-made AR pistol configured for the 10mm cartridge with modern features and clear manufacturer markings.
