The CMMG Resolute Mk5 G45 ACP 16.1" semi-automatic rifle delivers versatile, reliable .45 ACP performance in a compact platform designed for tactical operators, law enforcement, and specialized applications where a centerfire rifle firing handgun ammunition offers logistical and performance advantages. Built on CMMG's proven Resolute platform, this 16.1-inch barrel carbine combines the proven .45 ACP cartridge with modern ergonomics and modular components.
The 16.1-inch barrel with 1/2x28 threaded muzzle accommodates suppressor mounting or muzzle devices, while the factory zeroed muzzle brake aids recoil management. Cerakote armor-black finish provides corrosion resistance in varied environments. The 15-inch free-float M-LOK handguard offers clean sight lines and accessory mounting without barrel contact, ensuring consistent accuracy. Magazine capacity reaches 26 rounds using Glock-pattern magazines, streamlining ammunition logistics for operators already equipped with Glock platforms. The polymer grip and manual safety provide traditional rifle ergonomics, while the included Ripstock rear support enhances shouldering stability.
This rifle addresses niche demand among tactical shooters, armors, and agencies seeking .45 ACP rifle performance without duplicating 9mm or 5.56 logistics. The cartridge delivers substantial subsonic velocity—ideal for suppressed operations—while the Glock magazine ecosystem reduces spare parts inventory. The 26-round capacity and accessible ergonomics suit patrol, training, and specialized tactical roles where the .45 ACP platform is preferred over conventional rifle calibers.
One 26-round magazine ships with the rifle. M-LOK slots support mounting of optics risers, foregrips, lights, and other tactical accessories without rail clutter. The free-float barrel design minimizes harmonics, supporting consistent shot placement during duty or range use. Operators should verify local and state regulations regarding .45 ACP rifle ownership and specifications before purchase.
