A Proof Research pre-fit barrel cut for the Tikka T3x, chambered in 7mm PRC at 22 inches. Pre-fits are what make barrel swaps accessible to owners rather than only to gunsmiths: the shank, shoulder and headspace are cut to the platform's standard, so with a barrel vise, action wrench and headspace gauges the change is a manageable shop job.

Proof's carbon fiber wrapping over a match-grade steel core keeps weight low and heat management good. Pairing the 7mm PRC with a Tikka action produces a light, hard-hitting mountain rifle. Verify fit and headspace before firing.
