This is a piece I took off of a long barrel. The ROT is 1:70". The muzzle is crowned properly and the front sight dovetail is cut. It is blackened except the end that was cut. It would make an interesting .54 caliber "derringer" style pistol, or a powder tester....whatever....even a pen holder. Put a breach plug and drill a touch hole and you'd be half way to something unique. I won't throw it away, so I'd trade for anything interesting that is muzzleloader/black powder related.
