CMMG® Resolute Mk4 Semi-automatic 5.56 NATO/.223 Rem. AR-15 Rifle

When full-size rifles are too cumbersome and pistols/SBRs don’t deliver the long-range ballistic performance you need, the CMMG Resolute Carbine is the answer. The Resolute 300 is CMMG's top-of-the-line Carbine, and comes with premium components across the board. It features CMMG's own RipStock, which features FastBack technology for rapid deployment: just pull it straight back to deploy it. There are no locking tabs to bind, and an indexing screw lets you pre-set your desired length.

The Resolute Mk4 is loaded with CMMG's own ZEROED^TM components, from the pistol grip to the muzzle brake. Each component is American-made and delivers a higher level of performance than standard mil-spec. The new EML 15 handguard provides outstanding stability without unnecessary weight. 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 position with the omission of a full-length Picatinny section found on CMMG's previous handguard. This reduces weight while giving you plenty of real estate to mount those must-have accessories.
