This Proof Research pre-fit barrel is made for Zermatt Arms TL3 and SR3 short actions and chambered in 22 ARC. The shouldered pre-fit design threads on and torques down, so you can upgrade or change calibers without a gunsmith; always check headspace. Carbon fiber wrap cuts weight and helps the barrel shed heat.
