The Proof Research Zermatt TL3/SR3 LA Pre-Fit 7 PRC 22" 1-8 Twist Carbon Fiber Barrel is built for shooters who want a precise, lightweight upgrade for their long-action Zermatt rifles. This carbon fiber–wrapped steel barrel combines a Sendero contour with a 22-inch threaded muzzle, delivering excellent accuracy while shedding weight compared to traditional all-steel barrels.

Designed as a shouldered pre-fit, this barrel is ready to install on compatible Zermatt TL3 and SR3 actions with minimal gunsmithing—just thread, torque, and verify headspace. Its 7mm PRC chamber, 1:8 twist rate, and 5/8x24 threads make it ideal for modern long-range hunting and extended range sessions where consistency and heat management matter. Whether you are stretching distance on steel or dialing in a precision hunting rig, this barrel reflects Proof Research’s focus on innovation, craftsmanship, and real-world performance.
