.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.
Spiral Fluted Heavy Profile Barrel
The spiral fluting reduces weight while maintaining the rigidity of a heavy profile barrel. Combined with the nitride finish on stainless steel, this design enhances heat dissipation during extended shooting sessions, resists corrosion, and improves barrel harmonics for consistent shot placement at distance.
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.
Micro Low-Profile Gas Block
The .750 O.D. steel micro low-profile gas block maintains a clean sight picture and pairs with the Mid-Length gas system to deliver smooth cycling with reduced recoil impulse. This configuration ensures reliable operation across various ammunition loads.
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.
