If you’re looking for the ultimate pistol caliber carbine chambering, don’t sleep on .40 S&W. This MkGs® RESOLUTE® Upper Group is designed to extract the full, hard-hitting performance of .40 S&W in a package that’s easy to shoot with style in a class of its own. Available in seven different Cerakote finishes, all CMMG® Upper Groups come complete with bolt carrier group and ZEROED™ accessories including:
ZEROED AR15 Polymer Dust Cover
ZEROED AR15 Ambi Charging Handle
ZEROED Muzzle Brake 45ACP
Radial Delayed Blowback™ Operating System
Originally developed for the .45 ACP MkG platform, CMMG has adapted our Radial Delayed Blowback system across our pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems. Check out our CMMG Resources article & video to learn more about what sets Radial Delayed Blowback apart.
All CMMG .40 S&W MkGs uppers are only designed for use with MkGs lowers. CMMG cannot guarantee function with other manufacturers’ lowers.
