Introducing the PROOF Research® Tundra Rifle

PROOF Research®’s newest long-range hunting platform, the Tundra rifle, is designed to meet the toughest and most challenging hunting environments and won’t weigh you down getting there.

Columbia Falls, Mont. (May 2021) PROOF Research®, an innovator in precision rifle technology, announces their latest model rifle to hit the market: the Tundra rifle. Combining the adjustability and performance of a tactical rifle, with the design necessary to meet the demands of high-country hunting, the Tundra rifle is an exceptional long-range, lightweight hunting rifle.

The Tundra bolt-action rifle is the next generation of PROOF Research’s popular hunting rifle, the Terminus. With a starting weight of only 7 lbs. 3 oz., the Tundra, and its carbon fiber stock and a Sendero contour carbon fiber barrel, keep weight to a minimum without sacrificing any of PROOF Research’s “Terminally” accurate sub ½ MOA accuracy.

“The design of a monte carlo stock is timeless and a long running staple for hunting rifles.  We took this timeless design to the next level by adding adjustability.  At 7lbs., the Tundra is an already incredible hunting platform, before the addition of any optics or muzzle devices,” Kelly Streiff, Vice President of Sales & Marketing for PROOF Research, said. “The last thing a hunter needs to worry about is the weight of their rifle system.  There are many lightweight rifles out there, but many come sacrificing  accuracy for weight.  The Tundra embodies everything that we stand for, which is to develop a lightweight rifle that maintains and delivers extreme long-range accuracy.”

The Tundra’s lightweight, ergonomic carbon fiber stock features an adjustable Monte Carlo-style adjustable cheek piece for a customized fit. The BDL-style magazine ensures perfect cartridge seating every time and a smooth feed. The TriggerTech trigger’s crisp break and very short reset allow the user to make follow-up shots with greater precision and accuracy. Machined to tighter tolerances, the Defiance Ruckus bolt-action has a guaranteed headspace of +/-.001” making it one of the most accurate actions for long-range hunting. Completing the ultimate long-range hunting Tundra rifle is PROOF Research’s own Sendero contour carbon fiber barrel, specifically designed for long-range accuracy and performance, no matter the environmental extremes. The barrel comes threaded 5/8-24 with a thread protector and is ready for the installation of any aftermarket muzzle device.
