Proof Research Tundra .300 PRC 22″ Bolt Action Rifle

The Proof Research Tundra .300 PRC 22″ Bolt Action Rifle represents a deliberate convergence of modern materials and time-honored gunsmithing. Built around a carbon-fiber-wrapped match-grade barrel and a Defiance Ruckus action, this rifle is chambered in the hard-hitting .300 PRC—a cartridge designed for long-range precision. The 22-inch threaded barrel, with a 1-in-9 rate of twist, is paired with a Black Jungle Tundra stock for a subdued, professional profile. Every Tundra carries a Sub 1/2 MOA guarantee, a promise of accuracy that serious shooters can bank on.

Key Features

• Carbon-Fiber-Wrapped Barrel: Why it matters: Reduces overall weight without sacrificing barrel stiffness or heat dissipation, allowing for sustained precision strings in the field or at the range.
• Defiance Ruckus Action: Why it matters: A controlled-round-feed action with a three-lug bolt, providing smooth cycling and a rock-solid lockup that enhances consistency shot after shot.
• Black Jungle Tundra Stock: Why it matters: This stock is hand-laid with a textured finish for a non-slip grip in wet conditions, and its ergonomics promote a natural cheek weld for repeatable eye relief.
• Sub 1/2 MOA Guarantee: Why it matters: This guarantee is a manufacturer-verified standard of accuracy, meaning your rifle is tested to deliver groups under half a minute of angle—a benchmark for precision hunting and long-range competition.
• 22″ Threaded Barrel (5/8×24): Why it matters: The threaded muzzle accommodates suppressors or muzzle brakes, reducing recoil and noise, while the 1-in-9 twist stabilizes heavy 220-grain bullets typical of the .300 PRC.

Who It’s For

This rifle is for the collector who values engineered precision and the hunter who demands a lightweight, accurate platform for long-range shots on elk or mule deer. It also suits the competitive shooter who needs a rifle that can hold its own at 1,000 yards without breaking a sweat. If you appreciate the marriage of carbon-fiber innovation with a classic bolt-action pedigree, the Tundra is built for you.

Pros & Cons

• Pro: Sub 1/2 MOA accuracy out of the box—verified by Proof Research’s own testing.
• Pro: Lightweight at approximately 7.5 lbs, making it carry-friendly for backcountry hunts.
• Con: The .300 PRC ammunition is still less common than .308 or 6.5 Creedmoor, so you may need to order online or reload to keep it fed. This is a niche cartridge, and availability can be spotty.
