LOWER GROUP, RESOLUTE, Mk9, Radial Delayed Blowback, Mil-Spec Trigger
As the original 9mm platform from CMMG®, the Mk9 has evolved over time with improvements like Radial Delayed Blowback™ to provide shooters a platform with less felt recoil and a lighter BCG. Designed to accept Colt-style 9mm SMG magazines, this RESOLUTE® lower group is just the thing to kick off a 9mm carbine build. Available in seven different Cerakote finishes, RESOLUTE Mk9 lowers come with a suite of meticulously engineered CMMG parts and accessories like:
ZEROED Extended Mag Release Button
