A Proof Research carbon fiber barrel in 7mm SAUM, listed by the distributor as a drop-in barrel for the Tikka T3x. It is 22" long in the Sendero contour with a 1:8.4 twist. Carbon fiber construction trims weight from the rifle while keeping a heavier-profile barrel, a common choice for hunters who want a light rifle that still holds its zero through a string of shots.
