Green Mountain Thompson Center Barrel 32 15/16 54 cal smooth bore Barrel Rare!! . 54 cal equivalent to a 28 gauge and 28 ga shot wads would work with it. This is definitely an unusual barrel. You don’t see that many Green Mountain barrels and I’ve never seen another smooth bore, but I’m sure there’s a few has a little bit of edgeware on it right by the Green Mountain emblem and the 54 caliber. Other than that, super nice. The bore is an excellent condition. I do not have a ram rod for it. This is how I got it. It is a 15/16. So will fit a standard 45 or 50 cal Hawken stock. This is a very rare find.
