PROOF Research 155264 Bolt .224, 26-Inch, 1:7 Twist PXT Extra Barrel

The PROOF Research 155264 Bolt .224 PXT Extra Barrel is designed for shooters and builders seeking a specialized barrel component for a compatible bolt-action setup. Identified by part number 155264, this PROOF Research barrel features a .224 bore designation, a 26-inch barrel profile, and a 1:7 twist rate. The PXT designation is included as part of the manufacturer’s product identification and should be matched against your firearm, action, and configuration requirements before purchase.
As an extra barrel option, this component can support a compatible rifle configuration where a replacement or alternate barrel is required. The 1:7 twist rate is a key specification for ammunition selection and should be evaluated alongside bullet weight, cartridge specifications, chambering, and the intended use of the rifle. Because barrel compatibility depends on the specific action, bolt, chamber, threads, contour, and gunsmithing requirements, confirm all application details with PROOF Research or a qualified gunsmith before installation.
The PROOF Research name and part number 155264 provide clear identification for ordering, replacement planning, and configuration management. Use the complete product designation—Bolt .224, 26-Inch, 7TW, PXT Extra Barrel—when comparing this component with your existing setup or evaluating it for a custom rifle project. Professional installation, headspace verification, and appropriate inspection are recommended for any replacement or alternate barrel.
