The Proof Research .308 Win carbon fiber pre-fit barrel for the Tikka T3X is a 16.5-inch Sendero-contour replacement (brand part no. 138687). Proof Research says its pre-fit Tikka barrels are designed to torque on and be checked with proper headspace gauges. A carbon fiber wrap cuts weight against a steel barrel of similar contour. The 1:10 twist and 5/8-24 muzzle thread suit the cartridge and a suppressor or muzzle device.
