Proof Research Tundra TIX 7MM PRC 22″ — Bolt Action Rifle

The Proof Research Tundra TIX 7MM PRC 22″ bolt action rifle is a factory-built precision platform that pairs a carbon-fiber-wrapped match-grade barrel with a Defiance titanium action inside a Black Jungle Tundra carbon-fiber stock. It weighs under 7 lbs and carries a factory Sub 1/2 MOA accuracy guarantee. This is a purpose-built long-range hunting and steel-ringing tool, not a compromise.

Key Features

• Carbon-fiber-wrapped match barrel: Proof Research’s proprietary CF-wrapping process reduces barrel weight by roughly 40% compared to a steel contour of the same diameter, while the match-grade steel liner maintains sub-MOA consistency round after round.
• Defiance titanium action: The Defiance anti-titanium receiver shaves ounces off the build without sacrificing lug engagement or bolt throw smoothness—critical for a rig you’ll carry over terrain.
• Black Jungle Tundra carbon-fiber stock: This stock is bedded for the action and barrel channel, providing a rigid, vibration-dampening foundation that won’t shift with temperature or humidity.
• Sub 1/2 MOA guarantee: Proof Research backs every Tundra TIX with a factory accuracy guarantee of 0.5 MOA or better with match ammunition. That’s not a marketing claim—it’s a spec you can verify at the range.
• 5/8×24 threaded muzzle: The 22″ barrel comes threaded 5/8×24, letting you attach a suppressor, brake, or blast can without a gunsmith. The thread protector is included.

Who It’s For

The Tundra TIX is built for the precision rifle shooter who demands a lightweight, packable rifle that still prints sub-MOA groups at 800+ yards. It’s ideal for backcountry hunters who need to carry a rifle all day and then make a 600-yard shot on a mule deer, or for the PRS/NRL shooter who wants a factory gun that can hang with a custom build. If you’re the kind of shooter who measures groups in MOA and packs a Kestrel, this rifle is for you.

Pros & Cons

• Pro: Factory Sub 1/2 MOA guarantee eliminates guesswork—you know the rifle will shoot before you buy it.
• Pro: Under 7 lbs fully dressed, making it one of the lightest production precision rifles in 7MM PRC.
• Con: The 22″ barrel sacrifices 50-75 fps in muzzle velocity compared to a 24″ or 26″ tube, which can matter at extreme transonic ranges beyond 1,200 yards.
• Con: The carbon-fiber stock has a fixed length of pull—no spacers or adjustment system for different shooter builds.

FAQ

Does the Tundra TIX come with a scope rail or rings?

No. The rifle ships with a Picatinny rail installed on the Defiance action (20 MOA cant), but you’ll need to provide your own rings and optic. The rail is standard 0 MOA base pattern—most 34mm and 30mm rings will fit.

What twist rate is the barrel?

Proof Research specs a 1:8 twist rate for the 7MM PRC chambering. This stabilizes bullets from 160 to 180 grains, which covers the majority of long-range hunting and match loads.

Can I suppress this rifle without a muzzle brake?

Yes. The 5/8×24 threads accept any direct-thread suppressor or QD mount that uses that thread pitch. The barrel is thick enough at the muzzle to handle a suppressor without POI shift issues, though Proof recommends checking torque after 50 rounds.

Is the stock adjustable for length of pull or cheek height?

No. The Black Jungle Tundra stock has a fixed length of pull (13.5″) and no adjustable cheekpiece. Shooters with longer or shorter arms may need a gunsmith to add a spacer or aftermarket pad.

What is the magazine capacity?

The Tundra TIX uses AICS-pattern magazines. It ships with one 3-round magazine. You can swap in any AICS short-action magazine for higher capacity, though 5- and 10-round options may extend below the stock.
