CMMG Resolute MK4 5.56 16.1" Midnight Bronze

CMMG Resolute MK4 5.56 NATO Rifle

The Resolute MK4 represents a thoughtful approach to the modern sporting rifle. Chambered in 5.56 NATO, one of the world's most proven and widely available cartridges, this rifle delivers reliable performance whether you're training, competing, or hunting.

Design and Ergonomics

CMMG has equipped the Resolute MK4 with genuine ambidextrous controls throughout. This means both left and right-handed shooters operate the rifle with equal facility:

• Ambi Safety: 60/90-degree selector lever
• Ambi Charging Handle: Reciprocating handle on both sides
• Ambi Mag Catch: Magazine release functions from either side
• Extended Mag Release Button: Easier manipulation under stress or with gloves
• Bolt Catch: Locks the bolt to the rear when the magazine is empty

Handguard and Accessory Mounting

The EML handguard provides extensive M-LOK mounting slots on the sides and bottom, plus M-LOK sections between the top Picatinny rail segments. This gives you genuine flexibility in mounting lights, lasers, grips, and other tactical accessories exactly where you need them.

Trigger and Controls

The rifle ships with a ZEROED drop-in trigger and ZEROED pistol grip, both designed for smooth, predictable operation. A polymer dust cover protects the receiver when no optic is mounted.

What's Included

Each rifle comes with a Magpul PMAG 30-round magazine—a proven, reliable standard in the industry.
