Thompson Center Arms Breech Plug 50 Cal for Black Diamond/Woods Muzzleloader Rifle

The Thompson Center Arms Breech Plug is a factory replacement component designed specifically for the T/C Black Diamond and T/C Woods muzzleloader rifles. This single-piece steel breech plug threads into the breech end of the barrel to provide a reliable seal in the 50 caliber bore during loading and firing, making it an essential part for keeping your muzzleloader running.

Built to factory specifications, the plug carries a natural silver (unfinished) steel finish. Black Diamond and Woods rifle breech plugs are fully interchangeable between the two platforms; however, this part is not compatible with the T/C FireHawk due to differences in forward stock bolt placement. Proper fitment requires keeping the breech threads clean and applying a light film of grease before installation to prevent the plug from seizing in the breech over time.

Whether you are replacing a lost, damaged, or seized original, or simply keeping a spare on hand for the range or field, this genuine Thompson Center Arms breech plug delivers the dependable fit and seal your Black Diamond or Woods rifle needs for consistent ignition.
