Item # 248261 Style CMM-55A9D0B-MB UPC 810144722788 Condition New Manufacturer [CMMG](https://www.kygunco.com/brand/cmmg) Model Resolute MK4 Hand Right Hand Finish Bronze Round Capacity 30 Caliber 5.56 NATO, 223 Rem Action Semi-Auto Barrel Length 16.1 in When it comes to dimensions and the caliber, this is what comes to most people’s minds when you say AR15. This CMMG® RESOLUTE® comes chambered in 5.56x45mm, one of the most prolific calibers in the world, and for good reason. 5.56, and its counterpart .223 Rem, have seen service with militaries, hunters, and recreational shooters for decades. Whether you’re considering your first rifle or picking a new addition, a 5.56 RESOLUTE carbine is a staple for any collection. If you’re after a particular look or have a certain AR accessory that fits you best then don’t worry, this 5.56 RESOLUTE is built on our Mk4 platform and accepts virtually any and all AR15 accessories. 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. Mk4 ZEROED parts and accessories – Quality comes standard The AR15 platform is well known for its capability for customization but picking the right parts doesn’t have to be a nightmare of homework. CMMG’s ZEROED parts and accessories are made here in the USA with quality and attention to detail that is second to none and each RESOLUTE comes equipped with a slew of ZEROED parts standard, including: - ZEROED Drop-In Trigger - ZEROED Pistol Grip - ZEROED Trigger Guard - ZEROED 60°/90° Ambi Safety - ZEROED AR15 Ambi Charging Handle - ZEROED Ambi Mag Catch - ZEROED Extended Mag Release Button - ZEROED AR15 Bolt Catch - ZEROED AR15 Polymer Dust Cover - ZEROED Muzzle Brake 5.56mm Lifetime Quality Guarantee We aim to please, that’s why every CMMG product is backed by our Lifetime Quality Guarantee against material and workmanship defects.
