CMMG Banshee MkGs Pistol | .45 ACP | 8″ Barrel

The CMMG Banshee MkGs is a compact pistol-caliber AR-style pistol chambered in .45 ACP with an 8″ barrel and a 7″ M-LOK handguard. It uses CMMG’s MkG Radial Delayed Blowback operating system and is built to accept Glock-pattern .45 ACP magazines. For a red-dot that pairs well without exceeding $1,000, consider a small reflex like the Holosun 507K series; it provides a low-profile sight picture suitable for the Banshee’s footprint. This platform suits competitive pistol-caliber matches and range training where a stout .45 ACP option with AR ergonomics is preferred.
