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.

When full-size rifles are too cumbersome and pistols/SBRs don’t deliver the long-range ballistic performance you need, the CMMG RESOLUTE line of carbine length rifles is the answer. Fitted with the suite of ZEROED parts and accessories as well as our legendary RIPSTOCK, the RESOLUTE is the rifle that’s never out of place. The new EML™ 15 handguard brings style to the next level. M-LOK® attachment slots are found where expected at the 3, 6, and 9 o’clock positions as well as on top at 12 o’clock with the omission of a full-length Picatinny section found on our previous handguard. This reduces weight while the additional M-LOK section still gives shooters a place to mount those must-have accessories. With a range of choices, just pick the caliber you need for the job and let your rifle do the talking.

 

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.

 

Mk4 ZEROED parts and accessories – Quality comes standard

The AR15 platform is well known for its capability for customization but picking the right parts doesn’t have to be a nightmare of homework.
