CMMG Resolute MK4 6mm ARC 16.1" Tungsten

The CMMG Resolute MK4: Precision Meets Practicality

The 6mm ARC (Advanced Rifle Cartridge) represents a thoughtful evolution in rifle design. Introduced in 2020, this cartridge delivers ballistic performance that rivals larger rounds typically found in full-size AR10 platforms—all within the familiar AR15 form factor.

Why 6mm ARC?

This flat-shooting round excels where full-size rifles become unwieldy and shorter platforms fall short on range. It's an ideal choice for:

• Extended-range hunting with predictable, consistent performance
• Precision target shooting at distance
• Practical applications where a balance between power and manageability matters

Built for Real-World Use

The Resolute MK4 combines purpose-driven engineering with refined ergonomics:

• EML 15 Handguard: Modern M-LOK attachment points at 3, 6, 9, and 12 o'clock positions provide mounting flexibility without unnecessary weight
• RIPSTOCK Controls: CMMG's legendary ergonomic design ensures intuitive operation under any condition
• ZEROED Components: Factory-selected parts ensure reliability and consistency from the first shot
• 16.1" Barrel: Optimal balance of velocity, handling, and practical accuracy

A Rifle Without Compromise

When your mission demands more than a pistol or short-barreled rifle can deliver, but a full-size platform proves too cumbersome, the Resolute answers the call. Choose your caliber. Let your rifle do the talking.
