Description
The Proof Research Tundra .300 PRC 22″ Green Jungle Bolt Action Rifle is a precision long-range hunting tool built for the backcountry shooter who demands sub-MOA accuracy without packing a boat anchor. This rifle pairs a carbon-fiber wrapped match-grade barrel with Proof’s lightweight Green Jungle Tundra stock, cutting weight while keeping the barrel cool on hot days. The 22-inch barrel is threaded 5/8×24 for suppressor or brake use, and it rides on a Defiance Ruckus action with a Sub 1/2 MOA guarantee. At $7,299, it’s an investment in hitting what you aim at, mile after mile.

Key Features
- Carbon-Fiber Wrapped Match-Grade Barrel: This 22-inch barrel uses a carbon-fiber sleeve to shed heat fast and keep the bore true, which matters when you’re stacking shots at 800 yards and the sun’s cooking your position.
- Defiance Ruckus Action: A three-lug, 60-degree bolt lift with integral recoil lug gives you smooth cycling and a rock-solid lockup, cutting reload time on follow-up shots on a moving bull elk.
- Green Jungle Tundra Stock: The camo pattern blends into timber and sage, but the real win is the fiber-reinforced polymer that drops weight without flexing, so you can hump it over a ridge without a sore shoulder.
- Sub 1/2 MOA Accuracy Guarantee: Proof Research backs this rifle to shoot under half-minute of angle with match ammo, so you’re not guessing if the gun can do its part—it will.
- Threaded 5/8×24 Muzzle: The barrel comes threaded from the factory to accept a suppressor or brake, letting you tame recoil or noise without a gunsmith visit.
Who It’s For
This rifle is for the serious long-range hunter who spends more time glassing than walking. It’s built for guys who chase elk in open country, mule deer in the breaks, or pronghorn on the prairie—shooters who know that a 500-yard shot is a chip shot with the right gear. If you’re a weekend plinker, this is overkill. But if you’re the guy who packs a rangefinder and a wind meter, this is your rifle.
Pros and Cons
- Pro: Sub 1/2 MOA accuracy guarantee means you’re getting a true precision rifle out of the box.
- Pro: Lightweight at 7.2 lbs, easy to carry all day in rough terrain.
- Pro: Threaded barrel for suppressor use, a must for hearing safety on long strings.
- Con: The .300 PRC ammo is still scarce and pricey compared to .308 Win, so budget for match loads or handloading.

FAQ
What is the twist rate on the Proof Research Tundra .300 PRC?
The twist rate is 1-in-9 inches, which stabilizes heavy-for-caliber bullets like the 225-grain ELD Match or 212-grain Hornady ELD-X for long-range hunting.
Does this rifle come with a scope or rings?
No, the Tundra ships as a barreled action and stock only. You’ll need to add your own scope base, rings, and optic. We recommend a 20 MOA rail for dialing elevation at distance.
Can I use this rifle for hunting in all states?
Yes, the .300 PRC is legal for big game in all 50 states, but check local magazine capacity laws. The Tundra uses a detachable box magazine (typically 3-round) that may need a limit in some states.
How does the carbon-fiber barrel affect accuracy?
Carbon-fiber wraps reduce barrel whip and dissipate heat faster than steel, which means less point-of-impact shift during rapid fire. Per Proof Research tests, it maintains sub-MOA accuracy even after 10 shots in a string.
