PROOF BBL Stainless Steel Bolt 6-Dash DI 26" Competition Barrel 1:7.5 Twist Rate

The PROOF BBL Stainless Steel Bolt 6-Dash DI 26" Competition Barrel is a match-grade barrel built for shooters who demand precision. This 26-inch stainless steel barrel features a 1:7.5 twist rate and arrives from the factory ready for your gunsmith to thread and chamber to your exact specifications. Whether you're building a competition rifle, a long-range hunting rig, or a precision bolt-action platform, this barrel is engineered to deliver the accuracy that separates solid groups from winning groups.

PROOF Research brings over 15 years of barrel-manufacturing heritage to every barrel they produce. Starting in 2012 with the acquisition of Lawrence Barrels, PROOF has built a reputation for uncompromising quality in precision rifle barrels. Each barrel is manufactured in-house from double stress-relieved 416R stainless steel, a chromium stainless alloy specifically engineered for the demands of precision and match-grade applications. 416R was developed in direct collaboration with barrel makers and rifle manufacturers to deliver the consistency, durability, and surface finish that competitive and serious rifle builds require.

The 1:7.5 twist rate stabilizes a wide range of bullet weights, making this barrel adaptable to different load strategies without compromising accuracy. The 26-inch length provides the velocity and sight radius serious competitors and long-range hunters expect, while the stainless construction resists corrosion in field conditions. This is a barrel for builders who understand that a rifle is only as good as its foundation—and the barrel is where accuracy lives.
