CMMG Banshee Mk4 | 5.56 NATO | 10.5in | 30rd | Bronze

The CMMG Banshee Mk4 is a compact AR-style pistol built on CMMG’s modular Mk4 platform. Chambered for .223 Rem / 5.56 NATO and fitted with a 10.5 inch barrel, it pairs small overall length with carbine-derived features such as a .750 inch carbine gas system and a CMMG EML9 M-LOK handguard. This configuration ships with a 30-round magazine, an ambidextrous safety, a RIP brace and a bronze colored finish intended for users who require a short, modular shooting platform.

Recommended optic: a compact red-dot such as the Holosun 503CU complements the Banshee Mk4 and keeps the overall height low while providing fast target acquisition for close to mid-range work. Typical applications include precision-oriented range training and short-range competition where maneuverability and modular accessory options are priorities.
