Cmmg Dissent Mk4 338arc 10.5 10rd Ab

The CMMG Dissent Mk4 in .338 ARC with a 10.5-inch barrel represents a purpose-built platform for operators seeking a compact, hard-hitting rifle cartridge. The .338 ARC delivers significantly greater energy and penetration than standard intermediate rounds while maintaining controllable recoil impulse and magazine compatibility across AR-pattern receivers. This configuration prioritizes close-quarters effectiveness and reduced-signature performance in confined spaces, making it a specialized choice for precision shooters and tactical professionals who demand terminal performance beyond conventional options.

The 10.5-inch barrel length optimizes velocity for .338 ARC subsonic and supersonic loads while keeping overall system length manageable in vehicle entry, building clearance, and close-quarters scenarios. CMMG's Dissent platform delivers semi-automatic fire in a format that meets federal guidelines while maintaining the ergonomic and modularity standards of the AR ecosystem. The included 10-round magazine reflects the performance envelope of this cartridge. The Cerakote finish provides corrosion resistance suitable for prolonged field deployment, humidity-rich environments, and demanding operational contexts. Weighing 1 pound, the platform remains lightweight without sacrificing structural rigidity or accuracy potential.

This platform serves precision-focused operators, designated marksmen, and long-range hunting enthusiasts who need to engage targets beyond the effective range of 5.56/.223 platforms while maintaining a compact footprint. The .338 ARC is particularly suited to barrier-blind applications and engagement through intermediate barriers where conventional rifle cartridges may be overkill but standard intermediate rounds prove insufficient. Buyers should verify local and federal compliance before purchase, as some jurisdictions impose restrictions on semi-automatic rifle configurations.
