Description
The Proof Research Tundra TI is a premium bolt-action hunting rifle built around a lightweight titanium action and chambered in the high-performance 28 Nosler cartridge. Part of PROOF Research’s next-generation Tundra platform, the TI variant is a fully custom-built rifle featuring a hand-laid carbon fiber stock and a fully bedded action.
At the core of the Tundra TI is a black titanium receiver mated to a 24″ match grade threaded barrel with a 5/8×24 thread pitch and a protective thread protector installed at the muzzle. The barrel is wrapped in carbon fiber for outstanding stiffness-to-weight and rapid heat dissipation, and the 1:8.4″ twist rate is optimized to stabilize the long, heavy-for-caliber projectiles the 28 Nosler is built to drive.
The Tundra TI feeds through a box magazine offering a 4-round capacity for an overall 4+1 capability. A precision TriggerTech trigger provides a clean, crisp, user-adjustable pull, and the action uses a lever safety. The receiver is drilled and tapped for optics (no iron sights are included), so the rifle ships ready for a scope base and rings of your choice.
The stock is a hand-laid carbon fiber fixed-stock design finished in a TFDE camouflage pattern, with an adjustable cheek rest for proper eye alignment across different optic heights. The right-hand stock pairs naturally with the right-hand bolt action, and at 7.06 lbs total weight, the Tundra TI is one of the lightest titanium-action hunting rifles in its class – ready to carry on high-country stalks while still delivering long-range precision.
