PROOF Research PXT .264 18" Sendero Carbon Fiber Barrel Blank

Nothing about this one is finished. It is a rifled blank waiting on a chamber, a shoulder and threads, which is exactly what a custom build needs: the cartridge and the finished length are your call.

Eighteen inches of .264 bore in a Sendero contour leaves room to chamber and thread and still finish at a usable length for a 6.5 hunting or trainer build. The carbon wrap over a thin steel core is what makes a Sendero practical to carry: heavy barrel stiffness, nothing like heavy barrel weight, and heat that leaves the steel far quicker than it would on its own. PXT progressive rifling reduces the force needed to engrave a bullet and slows throat wear.
