The CMMG Resolute Mk57 5.7X28mm has recently become a favorite of shooters looking for a fast, lightweight round, offering excellent penetration at short range, with minimum recoil. Designed exclusively to accept FN Five-seveN style magazines, no AR functionality is sacrificed. In addition to the last round bolt hold open, the same magazines can be used for both the pistol and the carbine models. CMMG’s Radial Delayed Blowback operating system is present, delivering safer recoil impulse and reduced bolt weight – advantages that CMMG shares across all of their pistol caliber lines.

Each CMMG Resolute Mk57 5.7X28mm is a member of the family of carbine length ARs. These rifles provide long range ballistic performance, especially when full size rifles are too cumbersome, and pistol/SBRs cannot handle the job. Loaded with standard CMMG ZEROED features, Resolute models also include the EML 15 handguard. M-LOK attachment slots are at the 3, 6, 9 and 12 o’clock positions, with the omission of a full length Picatinny section found on the previous handguard. While still giving enough space to mount needed accessories, this omission reduces weight.

All CMMG Resolute Mk57 5.7X28mm rifles are crafted in the USA with meticulous attention to detail. In addition, they are backed by a Lifetime Quality Guarantee against material and workmanship defects.
