Overview
The PROOF Research GLACIER STEEL 7mm PRC Bolt-Action Rifle represents a commitment to uncompromising precision and robust field performance. Engineered for discerning shooters, this platform is designed to achieve repeatable accuracy across extended ranges, built around a meticulously machined steel action and a match-grade steel barrel.
Key Features
Precision Match-Grade Steel Barrel
This GLACIER STEEL rifle incorporates a 22-inch match-grade steel barrel, optimized for the 7mm PRC cartridge. The barrel features a 1:8 twist rate, an established optimal specification for stabilizing a wide range of modern 7mm projectiles, maximizing ballistic coefficient retention and terminal performance. The muzzle is threaded 5/8-24, facilitating the direct attachment of suppressors or muzzle devices without modifying the rifle’s inherent balance.
GLACIER STEEL Action Design
The GLACIER STEEL action is precisely machined from high-grade steel, ensuring exceptional strength and dimensional consistency. This robust foundation minimizes flex and maximizes lock-up integrity, critical factors for repeatable shot placement. The bolt operates smoothly within the receiver, promoting rapid and reliable cycling under various operational conditions.
7mm Precision Rifle Cartridge (PRC) Chambering
Chambered in 7mm PRC, this rifle capitalizes on a cartridge known for its flat trajectory, superior energy retention at distance, and effective wind bucking capabilities. This cartridge selection, paired with the GLACIER STEEL platform, provides a potent solution for long-range competitive shooting, precision hunting, or tactical applications where consistent engagement at extended ranges is paramount.
Reliability and Durability
Constructed with durable materials and KFF Defense’s stringent quality control, the GLACIER STEEL rifle is built for sustained performance. Each component is integrated to withstand the rigors of frequent use and diverse environmental conditions, ensuring functional reliability when it matters most.
