RESOLUTE®, Mk4, 5.7X28MM, 16.1”
Demand for personal defense weapons chambered in calibers like
5.7x28mm has been steadily growing over the years but picking the
right platform can be a tough decision. If the modularity of the Mk4
– AR15 platform piques your interest, then this RESOLUTE® Mk4
in 5.7x28mm is the thing for you. Instead of using pistol magazines,
this RESOLUTE uses our new generation of 5.7 magazines that fit
standard AR15 magwells for maximum modularity.
Radial Delayed Blowback™
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.
