PROOF Research 26" Stainless Steel Bolt-Action Barrel for .22LR - Fits Zermatt Competition, 1:16 Twist

The PROOF Research 26" stainless steel bolt-action barrel for .22LR gives precision rimfire shooters a match-grade upgrade path for their Zermatt Competition action. Built from stainless steel, this barrel handles the demands of competitive rimfire shooting, benchrest, or high-volume range sessions without the corrosion concerns of carbon steel. The 1:16 twist rate is optimized for reliable bullet stabilization across a wide range of .22LR ammunition, from standard velocity to hot handloads.

Stainless barrels are prized by shooters who want minimal maintenance and maximum longevity, especially when running high round counts without frequent cleaning breaks. The 26" length gives you velocity and sight radius while keeping the overall package manageable for precision work. Threading at 1/2-28 (the industry standard for .22LR rimfire suppressors and muzzle devices) means you have plenty of options to dial in your setup—whether that's adding a can for hearing protection or a custom brake.

Direct fit for Zermatt Competition actions means no gunsmithing or fitting required; this is a straightforward bolt-in upgrade. If you're building or upgrading a rimfire competition rig, or you simply want a stainless barrel that'll last through thousands of rounds with minimal fuss, this is solid brass-tacks gear.
