CMMG Resolute MK4 6mm ARC 16.1" Rifle - Coyote Brown Finish

The CMMG Resolute MK4 chambered in 6mm ARC delivers exceptional long-range performance in a versatile AR-15 platform. This rifle combines the flat-shooting characteristics of the 6mm ARC cartridge with CMMG's proven manufacturing quality for precision shooting applications.

What Makes This Different

The 6mm ARC chambering sets this rifle apart from standard 5.56 platforms, offering superior ballistic performance with less wind drift and energy retention at extended ranges. The 16.1-inch barrel length provides an optimal balance between velocity and maneuverability, while the medium taper profile enhances accuracy without excessive weight. CMMG's Resolute series incorporates upgraded components throughout the platform compared to basic AR-15 configurations.

Key Features

• 6mm ARC chambering for enhanced long-range ballistics and hunting capability
• 16.1-inch medium taper barrel with 1:7.5 twist rate optimized for 6mm projectiles
• Coyote Brown Cerakote finish for corrosion resistance and reduced visibility
• CMMG RipStock collapsible buttstock with enhanced cheek weld
• 15-inch M-LOK handguard with full-length top rail for optics mounting
• Geissele Super Semi-Automatic (SSA) trigger for crisp, consistent breaks

Field performance centers on the 6mm ARC's ability to maintain energy and accuracy beyond 500 yards, making this rifle suitable for precision shooting competitions, hunting medium game, and designated marksman applications. The cartridge's efficient powder burn and moderate recoil allow for faster follow-up shots compared to larger calibers. Weather-resistant finishes and quality components ensure reliable function across temperature and humidity ranges.
