8.6 BLK, the round that gives you more rifle with less barrel. Thanks to the quick 1:3 twist rate, 8.6 BLK hits it full ballistic potential with a much shorter overall barrel length compared to its AR10 contemporaries. If you're a fan of hunting suppressed then this is definitely the round for you, grab your new 8.6 BLK RESOLUTE, suppressor, and subsonic ammo and show those 300 BLK fans what stopping power means.Although there can be a lot of confusion with .308/AR10 AR platforms, CMMG has kept it simple by basing our Mk3 platform off the popular Gen 1 DPMS High-Pattern LR308 design, which means greater parts availability and more customization potential. 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.
