Key Features
- Carbon-Fiber-Wrapped Match Barrel: Why it matters—the barrel’s carbon-fiber wrap reduces weight while maintaining stiffness for consistent harmonics, crucial for sub-½ MOA accuracy in variable field conditions.
- Defiance Ruckus Bolt Action: Why it matters—this action provides a controlled-round feed with a smooth, 60-degree bolt lift, enabling fast follow-up shots without compromising extraction reliability.
- TFDE Carbon-Fiber Stock: Why it matters—the stock’s integrated bedding block and adjustable cheek riser offer a stable, custom fit that minimizes shooter fatigue during long stalks or mountain hunts.
- Threaded 5/8×24 Muzzle: Why it matters—threaded barrels allow direct attachment of suppressors or muzzle brakes, reducing recoil and noise for more comfortable shooting and better game recovery.
- Sub ½ MOA Guarantee: Why it matters—Proof Research backs this rifle to shoot under half-minute-of-angle with qualifying ammunition, giving you verified precision straight from the factory.
