Description

UPPER GROUP, RESOLUTE, 5.7X28MM, 16.1

Personal defense calibers like 5.7x28mm have become a big thing in the last few years, and if you’re looking for PDW ballistics and the classic style and balance of a carbine then you’re in luck. Combine this RESOLUTE® Upper Group with either our Mk57 Lower or a standard AR15 lower group and CMMG®’s 5.7 AR Conversion Magazines and you’ll be ready to hit the range! 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 5.56mm

 

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.
