Quickly becoming a fan favorite over the last several years, 5.7x28mm has found favor with those looking for a fast, lightweight round that offers excellent penetration at short ranges with minimal recoil.
The CMMG® Mk57 platform is designed exclusively to accept FN®* Five-seveN®* style magazines without sacrificing essential AR functionality, like last round bolt hold open. Not only can you have the same round in your pistol and carbine, but you can also use the same magazines for both!
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.
