.223 Wylde Chamber for Maximum Versatility

The .223 Wylde chamber specification accommodates both .223 Remington and 5.56 NATO ammunition while delivering match-grade accuracy. This chambering provides the flexibility to run mil-spec loads or precision match ammunition without sacrificing performance.

Nitride-Finished Government Profile Barrel

The government profile barrel with nitride finish combines proven weight distribution with a hard, corrosion-resistant surface that resists fouling and wear. The 1:7 twist rate ensures proper stabilization for heavier projectiles including 77-grain match ammunition and provides flexibility across the full spectrum of .223 Wylde loads.

Mid-Length Gas System

The Mid-Length gas system paired with the micro low-profile gas block delivers smooth cycling with reduced recoil impulse compared to carbine-length systems. This configuration ensures reliable operation across various ammunition loads while maintaining a clean sight picture.

Freefloat M-Lok Handguard

The M-Lok handguard freefloats the barrel for improved accuracy by eliminating contact pressure. M-Lok slots at multiple positions provide modular mounting for lights, grips, and other accessories without adding rail weight where you don't need it, while the lightweight aluminum construction maintains maneuverability.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify compatibility of all components before assembly. Performance may vary by ammunition type and configuration.
