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.

Caliber Dictionary
The Below Information Has Been Provided From Our Gun Caliber Dictionary And Is Meant For Informational Purposes Only. It Is Not Intended to Describe The Unique Specifications For This Ammunition.
The 5.7X28mm was introduced by FN in 1993, developed for a new concept called Personal Defense Weapon (PDW), intended to replace the pistol, submachinegun, and carbine for miliitary use. The concept is a compact, selective fire weapon intended for use within 200 meters, firing a light projectile for controllable recoil. The 5.7X28mm was designed for FN's P90 PDW. It uses a short bottlenecked case firing a 31-grain .224-inch bullet at 2325 fps. Performance exceeds military handgun cartridge, especially as range increases. Although many experts find the concept sound acceptance by the military has not been rapid. — Craig Boddington
