Item # 247115 Style CMM-55A9D0B-AB UPC 810144722757 Condition New Manufacturer [CMMG](https://www.kygunco.com/brand/cmmg) Model Resolute MK4 Hand Right Hand Finish Black Round Capacity 30 Caliber 5.56 NATO Action Semi-Auto Barrel Length 16.1 in Not only is 9mm one of the most prolific calibers for handguns, 9mm also makes a great choice for your next pistol caliber carbine. Although this CMMG® RESOLUTE® uses the same 9mm Radial Delayed Blowback™ upper system as our other 9mm RESOLUTES and BANSHEES™ this Mk4 RESOLUTE is unique in the fact that it uses our 9mm AR Conversion magazines. What’s the benefit of using an AR15 lower receiver? By swapping the upper group and magazine, you can change the caliber of your rifle in seconds. 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. Radial Delayed Blowback™ Operating System - Originally developed for the .45 ACP MkG platform, CMMG has adapted our Radial Delayed Blowback system across our pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems.
