CMMG Resolute Mk9
CMMG Inc. · Carbine · In Production · 2018
Also known as: Resolute Mk9, CMMG Resolute 300 Mk9
Overview
The CMMG Resolute Mk9 is a carbine-length AR-15 pattern semi-automatic pistol-caliber carbine chambered in 9x19mm Parabellum. Built on CMMG's dedicated Mk9 magwell that accepts widely available Colt-style 9mm SMG magazines, the Resolute Mk9 pairs a 16.1-inch barrel with CMMG's patented Radial Delayed Blowback operating system, which delays the bolt's rearward travel to substantially reduce felt recoil compared with the traditional straight-blowback pistol-caliber AR designs. The rifle ships with CMMG's ZEROED enhanced components including an ambidextrous charging handle and safety selector, a drop-in single-stage trigger, and the ZEROED muzzle brake. A 7075-T6 aluminum upper and lower receiver carry a Cerakote finish offered in numerous colors, and the M-LOK free-float handguard provides multiple mounting positions. A last-round bolt-hold-open feature and RipStock collapsible buttstock round out the package.

Notes
MSRP approximately $1,449. The Mk9 designation denotes CMMG's dedicated 9mm platform using Colt SMG-style magazines, distinct from the MkG/MkGs platform that feeds from Glock-pattern magazines. The Resolute Mk9 sits in CMMG's carbine-length Resolute family alongside the 5.56mm Mk4, 7.62x39mm Mk47, and 5.7x28mm Mk57. Overall length is approximately 32.5 inches with the stock collapsed-to-extended range; weight is roughly 6.4 lb (2903 g).
Background
CMMG introduced its Radial Delayed Blowback system to bring the recoil-taming benefits of a delayed action to the pistol-caliber AR market, and applied it across the Mk9 (Colt-mag) and MkGs (Glock-mag) 9mm platforms manufactured in Boonville, Missouri.
