This TC Prohunter Endeavor XT Encore Weathershield 28" Fluted 209x50 Muzzleloader Barrel is brand new and unfired. It is a take off barrel meaning I bought as a full gun, disassembled and sold the components so it is not in the original factory packaging. Weathershield is a new product for Thompson Center Arms in the Encore line but has been used for several years in the Omega and Triumph lines, and they say it is 50 times more corrosion resistant than stainless steel. This is a new production run, 28" fluted barrel, XT Speed Breech removes with your fingers with just a quarter turn. It is drilled and tapped for a scope and comes with factory front and rear sights. It also has the power T-handle ramrod. Check out the pictures.
