I haven’t tried to remove the nipple.Can you easily remove the nipple? Sometimes these get neglected and the nipples rust in place (through improper cleaning and/or lack of oiling before storage).
These can be incredibly accurate. People have won competitions using these against custom muzzleloaders. And you can upgrade the locks using and L&R if you want (or if you wear out the original).
It looks clean and you can blow through it. I can pull it out though if someone wants.
