PROOF Research BBL Stainless Steel Bolt 6-DASH DI 26" for Zermatt SA 1:7.5 Twist$656.25
Availability: In Stock
The PROOF BBL SS bolt action barrel in 6 Dash DI is a precision stainless steel barrel built for shooters who demand repeatability and durability without compromise. With a 26-inch tube, 1:7.5 twist rate, and direct compatibility with Zermatt actions, this barrel is engineered for long-range accuracy and tactical applications where barrel life and consistency matter. PROOF manufactures their stainless steel barrels using the same rigorous drilling, rifling, and lapping processes they apply to their carbon fiber offerings—meaning you get match-grade precision whether you choose steel or composite.
Built from double stress-relieved 416R stainless steel, this barrel starts with the same material science that goes into PROOF's composite barrels. 416R is a pre-hardened chromium stainless steel developed specifically for rifle barrel production, chosen by engineers and manufacturers across the industry for its ability to maintain consistent performance and withstand the thermal cycling and pressures of serious shooting. The in-house manufacturing process ensures tight tolerances and repeatability from barrel to barrel—critical factors if you're building a precision rifle that needs to perform predictably across different conditions and shooting distances.
This is a no-excuses barrel for builders who refuse generic compromises. Whether you're assembling a long-range hunting rifle, a competition platform, or a precision bolt gun, the PROOF stainless steel barrel brings factory-controlled quality and proven metallurgy to your build. If you're running a Zermatt action and want a barrel that matches that platform's engineering standards, this is the logical choice.
