Thompson Center Arms 8120R Encore Katahdin 500 S&W Mag 20" Silver S/S Brl E

The Thompson Center Arms 8120R Encore Katahdin barrel in 500 S&W Mag gives you a dedicated, swappable rifle barrel built for one of the hardest-hitting cartridges in the Encore system. If you already own an Encore Katahdin rifle and want to add serious magnum hunting capability—or if you're building out a multi-caliber platform—this 20-inch stainless steel barrel is the upgrade you need. It's drilled and tapped for scope mounts right out of the box, so there's no gunsmithing required to get mounted and ready to hunt.

Thompson Center's Pro Hunter barrels are fluted for strength and weight savings, and every barrel is test-fired at the factory to verify accuracy before it ships. The stainless steel construction handles weather and hard use without compromise, making this barrel as ready for backcountry hunts as it is for the range. This barrel fits Encore Katahdin rifles only—it's not compatible with Contender or G2 Contender frames, so verify your platform before ordering.

Swapping barrels on an Encore opens up your rifle to new hunting scenarios. A 500 S&W Mag barrel transforms your Katahdin into a serious tool for hunting big game where heavy, slow bullets and massive energy matter more than flat trajectory. Whether you're hunting in dense timber or setting up for a long wait in open country, having a dedicated magnum barrel ready gives you flexibility and purpose-built ballistics for the hunt.
