CMMG, based in Boonville, Missouri, is an AR-platform manufacturer known for engineering innovation. The company's radial-delayed blowback system reimagined how pistol-caliber and certain rifle ARs operate, smoothing recoil and improving reliability — a genuine contribution to the platform's evolution.
The Banshee is CMMG's signature line: a compact, configurable platform offered as a pistol, SBR, or carbine in a wide range of calibers from 9mm and .45 ACP up to 5.7×28mm and beyond. Alongside the Banshee, CMMG builds full-size AR rifles, conversion kits, and components, all reflecting the brand's focus on practical innovation and broad caliber options.
For shooters drawn to compact, soft-shooting pistol-caliber guns or CMMG's clever engineering, the brand offers a distinctive take on the AR platform.
