.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, this design enhances heat dissipation during extended shooting sessions, resists corrosion, and improves barrel harmonics for consistent shot placement.

9310 Alloy Steel Bolt Carrier Group

The included bolt carrier group is machined from 9310 alloy steel and finished with a nitride coating for enhanced durability and reduced friction. This material choice provides the strength and reliability needed for sustained use across various shooting conditions.

Lightweight Construction

The combination of 7075-T6 aluminum receiver and aircraft-grade handguard delivers a rigid platform without unnecessary weight. This construction maintains accuracy potential while improving handling and reducing shooter fatigue during extended range sessions.

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.
