The PROOF Research BBL Stainless Steel Bolt Action Rifle Barrel in .22 LR is built for shooters who demand precision and durability in a rimfire platform. This 20-inch stainless steel barrel pairs a 1:16 twist rate with a competition contour, designed to deliver consistent accuracy whether you're shooting at the range, training for precision rifle competition, or working with a dedicated .22 LR bolt gun. The threaded muzzle (1/2-28) accepts the included compensator, giving you control over felt recoil and muzzle rise—useful even in the mild .22 LR cartridge when you're chasing tight groups.
Built on PROOF Research's reputation for precision manufacturing, this barrel is machined from stainless steel for corrosion resistance and longevity. The competition contour strikes a balance between rigidity and manageable weight, keeping your rifle handy without sacrificing the harmonic stability that matters for repeatable accuracy. Whether you're building a dedicated rimfire trainer, a .22 LR benchrest rig, or upgrading an existing Zermatt-compatible action, this barrel gives you the foundation for genuine sub-MOA performance.
The included compensator helps manage muzzle movement, letting you see your impacts clearly and adjust quickly between shots—a real advantage in competitive shooting or when you're fine-tuning loads. Weighing 5 lbs 15 oz, the barrel is substantial enough to absorb vibration without being unwieldy, and the stainless construction means you won't worry about rust even if life gets in the way of regular cleaning.
