Key Features
- Proof Research Carbon-Fiber Barrel – WHY IT MATTERS: Reduces weight by 30% over steel while maintaining match-grade rigidity, minimizing barrel whip and heat soak for sustained accuracy.
- Defiance Ruckus Action – WHY IT MATTERS: Provides a controlled round feed and a 60° bolt throw for reliable extraction and fast cycling, even under cold or wet conditions.
- Green Jungle Tundra Stock – WHY IT MATTERS: Built from carbon-fiber with a textured grip panel, this stock resists moisture and temperature changes, ensuring consistent cheek weld and point of impact in alpine environments.
- Factory Sub-1/2 MOA Guarantee – WHY IT MATTERS: Eliminates guesswork—this rifle is verified to shoot 0.5-inch groups at 100 yards with match ammunition, saving you time and ammo on load development.
- Threaded Muzzle (5/8×24) – WHY IT MATTERS: Allows direct mounting of suppressors or muzzle brakes without gunsmithing, critical for reducing recoil and signature in tactical or hunting scenarios.
