STOCK UP and SAVE! Go to my store or “sellers other items” and type in “muzzleloader” to see more! NEW Thompson Center Hawken Flintlock Barrel. Very interesting KIT barrel! Yes a blued kit barrel without a K prefix. This was a finished excess barrel that Smith & Wesson put in a kit to clear out old inventory after purchasing TC. Still have the box as shown and the other kit parts available on other listings. Hooked breech, 50 Cal 15/16″ x 29″ overall length. Mint barrel that’s never even had a touch hole liner installed. We pride ourselves in offering a variety of quality production, custom and aftermarket replacement parts and supplies for black powder builders, shooters and enthusiasts of any level.
