CMMG MK4 Resolute Semi-Automatic Rifle .300 Blackout 16.1" Barrel (1)-30Rd Magazine CMMG RipStock Tan Finish

Delivering a heavy-hitting .30 caliber round on target, .300 BLK was originally designed around being a subsonic round for use in shorter barrel, suppressed rifles. Additionally, .300 BLK set out to utilize as many M4/AR15 parts and ammo components as possible. Although great for home defense and suppressed use in subsonic loadings, .300 BLK has evolved into a serious challenger to other intermediate cartridges like 7.62x39mm in supersonic form. Whatever your intended use may be, this RESOLUTE in .300 BLK, built on the Mk4 AR15 platform, features modularity and craftsmanship like no other.

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.
