CMMG Resolute MK4 6mm ARC 16.1" - AR-15 Rifle - 1x 10rd Mag - Tungsten

The CMMG Resolute MK4 is a semi-auto rifle chambered in 6mm ARC, built around a 16.1" stainless steel barrel, 6 Position RipStock, and EML 15" M-LOK handguard—finished in Tungsten Cerakote across the receiver, handguard, and stock for a muted, subdued profile suited to field and precision use where lower visual contrast is preferred.

The 16.1" stainless steel barrel treated with Black Nitride delivers the corrosion resistance of stainless construction alongside the surface hardness of a nitride treatment—two layers of protection across the bore and exterior simultaneously. The CMMG Zeroed Muzzle Brake manages 6mm ARC recoil for consistent, accurate follow-up shots, and the Zeroed Drop-In Single Stage trigger provides reliable pull weight across extended sessions. The 6 Position RipStock adjusts to accommodate different length-of-pull preferences.

The Picatinny rail receiver accepts a wide range of optic mounts directly. The EML 15" M-LOK handguard in Tungsten Cerakote provides comprehensive accessory mounting across the forend. Ships with one 10-round magazine. Thread pattern is 5/8"x24 for 6mm ARC muzzle device compatibility.

Receiver, handguard, and stock all carry Tungsten Cerakote for a uniform, muted appearance throughout the build. The Black Nitride stainless barrel provides a functional contrast point. At 6.40 lbs, the build is a lightweight option for a 16.1" precision rifle.

A natural choice for precision shooters who want the Resolute MK4's stainless 6mm ARC configuration in a Tungsten finish that blends cleanly across urban and natural environments without the higher visual contrast of black or bronze finishes.

CMMG applies Tungsten Cerakote to the Resolute MK4 to the same factory durability standard as all their receiver finishes, ensuring the muted coating holds up through sustained field and range use without additional surface treatment.
