Proof Research 6.5mm 20" Sendero Carbon Fiber Barrel Blank

A carbon fiber wrapped barrel blank in .264 (6.5mm) for a custom bolt action build. It measures 20" in the Sendero contour with a 1:8 twist and comes unchambered, so your gunsmith fits, chambers and threads it for your action and cartridge. The breech end is 2.5" long with a 1.20" shank diameter.

Proof rates the wrapped barrels as up to 64% lighter than steel barrels of a similar contour, and the carbon fiber helps move heat away from the bore.
