The Proof Research Carbon Fiber Barrel Blank, .284 Sendero Light, 22" is built for shooters who want match-grade precision without the bulk of a traditional steel barrel. Using a stainless steel core wrapped in a rigid carbon fiber sleeve, this 22-inch blank in .284 caliber delivers consistent accuracy while trimming significant weight from your custom bolt-action build.

This Sendero Light contour barrel blank features a 1:8.4 twist rate to stabilize common .284/7 mm projectiles used in long-range hunting and target shooting. With a breech length of 2.5 inches and a 1.20-inch shank diameter, it arrives ready for your gunsmith to thread and chamber to your preferred cartridge, making it an ideal foundation for a precision rifle focused on balance, handling, and repeatable performance backed by Proof Research’s innovation in carbon fiber barrel technology.
