CMMG Rslt Mk3 8.6blk 16.1" 20-Round Rifle

The CMMG Resolute Mk3 in 8.6 Blackout with 16.1-inch barrel delivers precision and power in a semi-automatic rifle platform purpose-built for intermediate-range engagement. Chambered in 8.6 Blackout—a cartridge engineered for subsonic and supersonic performance—this rifle bridges the gap between standard intermediate calibers and specialized long-range platforms, making it ideal for operators and serious shooters seeking ballistic flexibility without sacrificing practical accuracy.

The 16.1-inch barrel length optimizes velocity retention and handling in confined spaces while maintaining the efficiency of the 8.6 Blackout cartridge across both subsonic and standard-velocity loads. The Cerakote Armor Black finish provides corrosion resistance and durability in variable field conditions, protecting against moisture and abrasion during extended use. This Resolute Mk3 model ships with one 20-round magazine, offering substantial capacity for training cycles or operational requirements. The rifle's configuration supports the 8.6 Blackout's reputation for reduced report when paired with compatible suppressors—a consideration for shooters managing noise sensitivity on ranges or in training environments.

This platform serves competitive shooters, law enforcement trainers, and civilian operators who value the ballistic characteristics and ergonomic maturity of the CMMG brand. The 8.6 Blackout caliber appeals to builders and shooters exploring alternative intermediate cartridges that offer distinct performance profiles from mainstream options. Whether for precision rifle training, specialized applications, or expanding a collection with modern cartridge technology, the Resolute Mk3 delivers straightforward semi-automatic reliability backed by CMMG's engineering reputation. The included magazine and Cerakote finish represent a complete, ready-to-deploy package for immediate field or range deployment.
