RESOLUTE, Mk4, 22 ARC, 16.1"
5.56mm May be the staple caliber of carbine-size AR15s, but 22 ARC is the next generation of .22 caliber AR chamberings. Designed to provide consistent function from the AR-15 platform, 22 ARC delivers 22-250 levels of ballistic performance in the Mk4 (AR15) lineup.
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.
