Rifle, Resolute 100, Mk9, 9mm Radial Delayed Blowback™
As CMMG’s oldest 9mm platform, the Mk9 is continuing to go through changes to become even better than before. Introducing, the new and improved Mk9, now utilizing CMMG’s patented Radial Delayed Blowback™ operating system. Radial Delayed Blowback guarantees less felt recoil for the shooter, offering a more enjoyable shooting experience. Our Mk9 platform is designed to use Colt SMG-style magazines and is offered in both BANSHEE and RESOLUTE configurations.
The 100 Series features classic furniture appointments such as the beloved A2 pistol grip and a 6-position butt stock. Chambered in 9mm, this AR is ready for the range.
The Mk9 platform accepts Colt SMG-style 9mm magazines. It is the oldest of CMMGs 9mm platforms.
CMMG’s RESOLUTE rifle and carbine lineup is engineered with purpose for those who refuse to compromise on quality. Each RESOLUTE rifle is designed for balance, accuracy and maneuverability. Available in three tiers —RESOLUTE 100, RESOLUTE 200 and RESOLUTE 300 — that cater to your intended needs and customization. Whether you’re defending your family or looking to bring out your best at the range, the RESOLUTE keeps going when you need it most.
CMMG has made a small modification to 9mm barrels in order for them to be compatible with Mk9 lower receivers. This modification only applies to Mk9 platform lower receivers and does not positively or negatively affect functionality of the barrel with a MkGs, Mk4 or Mk17 platform lower receiver. Barrels that are stamped “9mm Luger” will be compatible with an upgraded Mk9 lower receiver. If your barrel is marked “9x19 NATO”, you will need to purchase a new 9mm barrel in order to ensure reliable function.
