Proof Research Tundra Ti X, a premium titanium-action rifle for backcountry hunters

Since 2021, Proof Research's catalog includes the Tundra rifle, an evolution of the Terminus model designed as a lightweight rifle for the toughest and most challenging hunting environments. Now comes an even more specialized and lightweight iteration featuring a cutting-edge titanium action – the Tundra Ti X.

Like the previous model, the Tundra Ti X is a rifle made for long-range hunters that blends tactical features and a classic Monte Carlo stock design, but in carbon fiber. The new right-hand Ti X titanium action from Defiance Machine provides a high-strength, ultra-lightweight receiver that complements Proof’s patented carbon fiber-wrapped, match-grade barrel and the adjustable TriggerTech Special Trigger. The combination of extremely lightweight receiver, carbon fiber stock, and carbon fiber barrel creates a premium backcountry hunting rifle ready for the most demanding environments.
