The MkGs lower is configured for small-frame Glock double-stack magazines and features a large paddle-style magazine release. The upper and lower are AR-15 pattern with a dust cover and brass deflector, and the radially lugged rotating bolt head confirms CMMG's Radial Delayed Blowback system. Controls include a manual safety and a CMMG-branded ambidextrous charging handle with extended latches.
The 5-inch barrel is threaded and capped with a multi-prong flash hider. A free-float aluminum M-LOK handguard provides a continuous top Picatinny rail and an integrated bottom QD slot panel, offering solid accessory mounting while keeping the front end light and compact.
Factory markings include CMMG INC BOONVILLE, MO USA, SAFE/SEMI selector markings, BANSHEE script, the CMMG gear logo, and MkGs roll marks. The grip is a textured polymer unit with the CMMG logo for positive purchase.
The Flat Dark Earth finish is uniform across the upper, lower, and handguard, giving this Banshee a cohesive appearance. It ships complete with Votatu flip-up sights installed and three magazines: two standard-length 17-round Glock factory mags and one extended 21-round Magpul PMAG GL9.
