The CMMG Resolute Mk3 .308 Win 16.1" rifle is a modern .308 battle rifle that splits the difference between full-size precision guns and compact pistol-caliber builds. Built on the proven DPMS High-Pattern LR308 platform, this direct impingement carbine gives you genuine rifle-range ballistics in a package that's equally at home on the range, in the field, or slung in your truck. If you've been hunting for a .308 AR platform that's lighter and easier to manage than traditional full-length rifles but packs more punch than intermediate-caliber options, this is it.
The Mk3 wears CMMG's EML15 M-LOK handguard—clean, purposeful, and stripped of unnecessary weight. Instead of a full-length Picatinny rail, you get M-LOK slots at the cardinal positions (12, 3, 6, and 9 o'clock), giving you genuine modularity without the bulk. The upper and lower receivers are billed 7075-T6 aluminum, threaded with a 416 stainless steel barrel (1:10 twist, MT contour) and capped with a CMMG ZEROED muzzle brake. Everything—from the ambi charging handle and 60/90-degree safety selector to the drop-in trigger and RipStock—comes from CMMG's ZEROED line, meaning the whole gun works together as designed.
This is a rifle that scales. The 6-position Fastback receiver extension and RipStock let you dial in your fit. The included Magpul 20-round PMAG keeps you legal and practical. At 8 pounds and 34 inches long, you've got a .308 you can actually carry all day. Whether you're planning distance work, tactical training, or a hunting season where reach matters, the Resolute Mk3 doesn't compromise.

The Mk3 is built on the DPMS High-Pattern LR308 platform, which has greater parts availability and customization potential than some other .308 AR designs. However, it uses LR308-pattern receivers and components, not standard .223 AR-15 parts, so ensure any upgrades you're considering match the platform.
The Resolute Mk3 is chambered in .308 Winchester (.308 Win), a full-power rifle cartridge suitable for long-range shooting, hunting, and tactical applications.
The rifle includes a Magpul 20-round PMAG magazine and is equipped with all necessary components—muzzle brake, bolt carrier group, trigger, and stock—ready to shoot. It ships with a standard field-strippable upper and lower assembly.
The Mk3 uses a non-adjustable 0.750" gas block with a rifle-length gas system. The gas block is fixed, so you cannot tune gas pressure on this model.
