Thompson Center Arms 8107R Encore Katahdin 360 Buckhammer 20" Silver S/S Br

The Thompson Center Encore Katahdin 360 Buckhammer barrel is a precision rifle barrel built for hunters ready to switch calibers without buying a new gun. This stainless steel barrel swaps into your existing Encore rifle frame—no gunsmithing required—letting you adapt to different game and seasons with one firearm platform. If you already own an Encore Katahdin, this 20-inch barrel opens up the leverage and stopping power of the modern 360 Buckhammer cartridge for mid-range deer and hog hunting.

Thompson Center engineers this barrel with fluting that maximizes strength while keeping weight down, and every barrel leaves the factory test-fired at 100 yards to confirm accuracy before it ships. The stainless steel construction stands up to weather and hard field use—no rust creep or corrosion headaches in wet conditions or after long storage. The barrel comes drilled and tapped for standard scope mounts, so you can mount optics immediately without sending it to a gunsmith.

The 360 Buckhammer is a relatively new cartridge designed specifically for modern inline and break-action hunting rifles. If you're considering this barrel, make sure your current setup is an Encore Katahdin frame; these barrels are Encore-specific and will not fit Contender or G2 Contender rifles. Swap it in, zero your scope, and you're ready to hunt.
