The Proof Research .308 Winchester carbon fiber pre-fit barrel for the Tikka T3x (brand part number 115084) is a 20-inch Sendero-contour barrel machined to the T3x barrel nut pattern for a straightforward drop-in upgrade. It is wrapped from aerospace-grade carbon fiber over a 416R stainless steel liner, cutting weight by as much as 64 percent versus a comparable steel barrel. Tikka T3x owners get one of the most popular precision rifle platforms on the market and a well-known accuracy reputation; this pre-fit trades the factory steel barrel for a lighter, stiffer carbon-fiber upgrade without a full custom gunsmithing job.
