Proof Research Zermatt TL3/SR3 22 ARC 20" Carbon Fiber Barrel

A shouldered prefit barrel from Proof Research for Zermatt Arms TL3/SR3 actions, chambered in 22 ARC. It is 20" in the Sendero contour with a 1:7 twist. Prefits like this thread on and torque down, then you check headspace and go shoot.

Proof guarantees headspace on its shouldered prefits but notes that barrels are specific to action type and length and are not interchangeable, so match it to your action before ordering. The carbon fiber wrap is up to 64% lighter than steel of a similar contour.
