Description
There are lightweight hunting rifles, and there are precision rifles, and most of the time you have to pick one. The Proof Research Tundra is the rare build that refuses to make that trade. Built in Montana around a Defiance Ruckus action held to headspace tolerances of plus or minus .001 inch, this Tundra wears a 22-inch carbon fiber wrapped Sendero contour barrel in 7mm PRC, and Proof backs the whole package with a sub 1/2 MOA accuracy guarantee. The 1:8 twist stabilizes the long, high BC 7mm bullets this cartridge was designed around, which is exactly what you want when a bull steps out at distance and the wind is doing its thing.
Why the Tundra 7mm PRC Carries So Well
The carbon fiber barrel is the headline here. You get the stiffness and heat management of a heavy Sendero contour without lugging a heavy rifle up the mountain, keeping the Tundra in genuinely packable territory before optics. The carbon fiber stock features an adjustable Monte Carlo style cheek piece, so you can dial in a proper cheek weld behind a big scope instead of floating your head over the comb. This one comes dressed in Proof's Black Jungle camo finish, a sharp look that also blends into timber and shadow.
Field-Ready Details on the Proof Tundra
The TriggerTech trigger breaks clean with a short reset, which makes a real difference on follow-up shots when your heart rate is up. Cartridges feed from a BDL style magazine system, so there is no detachable box mag to lose in the snow, and the one-piece pinned rail gives your optic a solid foundation. The muzzle comes threaded 5/8×24 with a factory thread protector installed, ready for a brake or suppressor whenever you are.
If you have been wanting one rifle that can ring steel at the range all summer and then earn its keep in elk country come fall, the Tundra in 7mm PRC is built for exactly that double life. Buy once, hunt everywhere.

Frequently Asked Questions
What kind of accuracy can I expect from the Proof Research Tundra in 7mm PRC?
Proof Research backs the Tundra with a factory sub 1/2 MOA accuracy guarantee. That level of precision comes from the combination of a match grade carbon fiber wrapped barrel and a Defiance Ruckus action machined to headspace tolerances of plus or minus .001 inch. With quality match or hunting ammo, this rifle will outshoot most of the people behind it.
Is the 22-inch barrel long enough for 7mm PRC?
Yes, 22 inches is a smart length for a hunting-focused 7mm PRC. You give up a modest amount of velocity compared to a 24-inch tube, but you gain a shorter, handier rifle that balances well with a suppressor attached. The 1:8 twist still stabilizes the heavy, high BC bullets that make this cartridge shine at long range.
Can I mount a suppressor or muzzle brake on the Tundra?
Absolutely. The muzzle comes threaded in the common 5/8×24 pattern with a factory thread protector installed, so most 7mm and .30 caliber brakes and suppressors will spin right on. Just confirm your device's bore diameter clears a 7mm bullet before mounting.
Does the Proof Tundra use a detachable magazine?
No, the Tundra feeds from a BDL style magazine system with a hinged floorplate rather than a detachable box. Proof went this route for reliable cartridge seating and smooth feeding, and many hunters prefer it since there is no magazine to rattle loose or lose in the field.
