Specs at a glance
About this product
The Proof Research Tundra Ti X 7MM PRC TFDE 22″ is a precision bolt-action rifle built for shooters who need consistent accuracy at extended ranges without hauling around a heavy rig. This rifle combines a Defiance titanium action with a carbon-fiber wrapped barrel and a TFDE Proof Tundra carbon-fiber stock, keeping weight down to 6 lbs. 13 oz. while maintaining the rigidity needed for tight groups. The 22″ threaded barrel uses a 1-in-8″ twist rate to stabilize modern long-range projectiles, making it a solid choice for hunting or target work out past 1,000 yards. Per Proof Research, this is a production-ready platform for shooters who demand match-grade performance from a lightweight field rifle.

Key Features
- Defiance Titanium Action — WHY IT MATTERS: Titanium cuts weight without sacrificing strength, so you get a durable, corrosion-resistant receiver that shaves nearly a pound compared to steel actions.
- Carbon-Fiber Wrapped Match-Grade Barrel — WHY IT MATTERS: The carbon-fiber wrap dissipates heat faster and stiffens the barrel, letting you shoot multiple rounds without losing zero, even in backcountry conditions.
- TFDE Proof Tundra Carbon-Fiber Stock — WHY IT MATTERS: This stock is rigid enough for a bipod and sling, but light enough at just over 2 lbs. to keep your total carry weight manageable on long stalks.
- 1-in-8″ Twist Rate — WHY IT MATTERS: That twist stabilizes heavy-for-caliber bullets like the 180-grain Berger and Hornady ELD-X, giving you better ballistic coefficients and flatter trajectories past 800 yards.
- Threaded 22″ Barrel — WHY IT MATTERS: You can attach a suppressor or brake directly without a gunsmith, reducing recoil and noise in the field.
Who It’s For
This rifle is for the hunter who hikes miles into public land and the precision shooter who wants a lightweight rig for PRS or long-range matches. It fits shooters who reload 7MM PRC and want a platform that squeezes every bit of accuracy out of modern projectiles. New gun owners will appreciate the ready-to-run setup, but it’s built for experienced shooters who understand wind calls and ballistics.
Pros & Cons
Pros: Under 7 lbs. fully dressed, sub-MOA accuracy out of the box, threaded barrel for suppressors, titanium action resists rust in wet conditions.
Cons: Price point is high at $7,499 — not a budget option. The carbon-fiber stock has limited adjustment for cheek height compared to some chassis systems. Ammo availability for 7MM PRC is improving but still tighter than 6.5 Creedmoor.
