Proof Research 113707 Bolt Action Blank 243 Cal 28 in Competition Contour 1:7.50 in Twist 4 Grooves, Stainless Stainless, Rifle Barrel

Overview

The Proof Research bolt action barrel blank is engineered for precision builders seeking exceptional accuracy and durability. Machined in-house from double-stress-relieved 416R stainless steel, this 28-inch competition contour blank provides an optimal combination of high tensile strength, structural toughness, and resistance to extreme chamber pressures, erosion wear, and corrosion. Each barrel undergoes precision drilling, contouring, reaming, single-point cut rifling, and hand-lapping, followed by borescope inspection to ensure rigorous quality standards. Featuring a 1:7.5-inch twist rate with four grooves in a .243 caliber configuration, this stainless steel blank delivers the consistency required for custom precision rifle builds.
