CMMG

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 dont 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 thats 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. - Platform Mk4 - Caliber .22 ARC - Operating System Direct Impingement - Barrel Length 16.1 - Barrel Twist 1:7 - Barrel Contour MT - Barrel Material 4140CM SBN - Barrel Twist 1:7 - Muzzle Device CMMG ZEROED Muzzle Brake - Muzzle Thread 1/2 x 28 - Gas Port Location Rifle - Gas Block Adjustable 0.750 - Upper Receiver Billet 6061 T6 Aluminum - Lower Receiver Mk4 Forged 7075 T6 Aluminum - Hand Guard CMMG EML15 M-LOK - Finish Cerakote - Charging Handle CMMG ZEROED Ambi - Pistol Grip CMMG ZEROED Pistol Grip - Buffer Type Carbine - Receiver Extension CMMG 6 Position Fastback w/Ambi Sling Plate - Stock / Brace CMMG RipStock - Trigger Type ZEROED Drop-In Single Stage - Trigger Guard CMMG ZEROED Trigger Guard - Safety Selector CMMG ZEROED 60/90 Degree - Magazine CMMG 10rd - Weight 6.4 lbs - Length 32.5
