The RESOLUTE, Mk4, .22 LR, 17" CMMG® Perfect for low-cost training, introducing new shooters to firearms, small game/varmint hunting, and some good old-fashioned mag dumps, .22 LR has long been a round that is beloved by many. With a 17” nitride finished barrel, this RESOLUTE® isn’t just a .22 that looks like an AR, it’s a full-blooded AR that just happens to be chambered in .22 LR. Being built on our Mk4 – AR15 platform means you not only get the ultimate .22 LR AR, but you can also change calibers in seconds by pairing your Mk4 lower receiver group with another AR15 upper receiver group (and corresponding magazines) in the caliber of your choice.

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.
