Item # 214188 Style CMM-55AC780-AB UPC 810046238622 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, 223 Rem Action Semi-Auto Barrel Length 16.1 in When it comes to dimensions and the caliber, this is what comes to most peoples 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 the Mk4 platform and accepts virtually any and all AR15 accessories. 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 the 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 their 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. #### SPECIFICATIONS - Brand: CMMG - Category: Tactical Pistols - Gun Platform: AR-Style - Caliber: 5.56x45mm NATO - Model: Resolute - Series: MK4 - Stock Finish: Black - Action: Semi-Auto - Sights: None, Optic Ready - Capacity: 30+1 - Muzzle: Compensator - Magazine Type: AR-15 - Gripsv Black Polymer - Hand: Right - Handguards: M-LOK - Max Capacity: 30 - OAL: 26" - Receiver Finish: Black Cerakote - Receiver Material: 7075-T6 Aluminum - Safety: Ambidextrous Safety Lever - Stock Description: CMMG 6 Position RipBrace - Stock Material: Synthetic - Thread Pattern: 1 / 2"-28 tpi - Trigger: Single-Stage - Twist: 1:7" - Weight: 5.90 lbs - Barrel Description: 4140 Chrome Moly Medium Taper - Barrel Finish: Black Nitride - Barrel Length: 16.10" ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
