The Proof Research Carbon Fiber Bolt-Action Barrel, 7mm, 20.00" Sendero Contour, Threaded, Stainless/Carbon Fiber is built for shooters who want a precise, repeatable barrel in a lightweight package. Its stainless steel core is wrapped in carbon fiber to deliver excellent rigidity while significantly reducing weight, and the 20-inch Sendero contour with a threaded muzzle is optimized for modern long-range performance.
This 7mm barrel uses a 1:8 twist rate to stabilize contemporary high-BC projectiles, making it well suited for long-range hunting and precision target work. The 5/8-24 threaded muzzle allows easy installation of brakes or suppressors, while the balanced Sendero profile helps manage heat without unnecessary bulk. Proof Research’s focus on advanced materials and meticulous craftsmanship gives shooters confidence in consistent accuracy shot after shot.
