Proof Research Glacier Steel 7 PRC 22 inches Threaded Barrel Rifle

The PROOF 140635 Glacier Steel 7PRC 22 8 5/8-24 BGR is a precision rifle engineered for long-range accuracy and lightweight field performance. Built on a Lone Peak Arms Razor action paired with a TriggerTech trigger, this rifle delivers the sub-half-MOA accuracy guarantee that defines PROOF Research's reputation among competitive shooters and long-range hunters. The carbon fiber Sendero threaded barrel—chambered in 7mm PRC—maximizes velocity while reducing overall system weight, a critical advantage for high-altitude and extended hunting expeditions.

The rifle ships with PROOF's Lightweight Mountain Hunter carbon fiber stock, engineered to minimize weight without compromising rigidity or ergonomics. The threaded muzzle (5/8-24 pattern) accommodates suppressors or muzzle devices common to precision shooting setups. A BDL-style magazine system ensures reliable feeding and quick-change capability. At 12.6 pounds, the Glacier Steel balances recoil management with the portability demanded by backcountry and competition environments. The included thread protector safeguards the muzzle during transport and storage.

This rifle is built for shooters who demand verified accuracy beyond 600 yards and hunters who won't compromise on precision or field practicality. The 7PRC cartridge balances velocity, case capacity, and recoil—ideal for medium to large game at extended ranges. The combination of match-grade action, precision trigger, and carbon fiber construction positions this platform equally at home in competitive tactical matches or wilderness hunts where every ounce and every tenth of an inch matters.

PROOF Research rifles are backed by measurable performance standards—the sub-half-MOA guarantee is not marketing language but a tested specification. The Glacier Steel reflects decades of precision manufacturing focused on eliminating variables that degrade accuracy in the field. Shooters selecting this rifle prioritize documented performance, component quality, and purpose-built engineering over general-purpose designs.
