Depending on the maker you can remove the breech plug and of course the sights and underlug. It is not an easy task to remove the plug and without proper tools usually results in a buggered up barrel or plug. You would need a barrel vise and a breech plug wrench, some heat and penetrating oil. I would recommend taking it to a gunsmith in your area.

The short answer is yes it can. I'm a muzzleloader gunsmith and T/C dealer of 30 years. I can remove it with a special tool, but I wont and neither should you. There is no reason to ever remove a breech plug from any traditional muzzleloader. Removal is not necesary for cleaning and I dont see any other reson to remove one. Of the few I have taken off, some took over a week and a six foot cheater bar to get off. Some just wrung off. T/C used to sell a tool for removing the breech plugs but customers using them were screwsing up the threads and sending them in for warrenty work. After that, about 1980, they started putting them on so tight and with so much industrial locktite, they are almost impossible to remove. Once again, I've never encountered a need or reason to remove one. RamblinMan
