CMMG Resolute MK4 Semi-Automatic Tactical Rifle 6mm ARC 16.10" 416 Stainless Steel Barrel (1)-10Rd Magazine Optic Ready Black CMMG 6 Position RipStock Charcoal Green Finish



Introduced in 2020, the 6mm ARC (Advanced Rifle Cartridge) was designed to deliver excellent ballistic performance in AR15 platform rifles that rivals the extended range performance of larger rounds typically chambered in the larger AR10/LR308 style rifles. This flat shooting round makes a great choice for hunters and extended target shooters looking for predictable performance out of a feature-packed rifle like the CMMG RESOLUTE Mk4. 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 oclock positions as well as on top at 12 oclock 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.
