Abstract: Accessories for muzzle-loading firearms including a wrench for working with the nipples of muzzle-loading firearms, with a cylindrical tubular body equipped with a truncated conical end with a circular longitudinal axial opening. A continuation of this opening, which is circular, receives replacement nipples controlled by the end of the opening itself and by a pin that goes through the base body. A nut plugs the opening in the tubular body and is screwed onto the other inside end of the base body. The nut is provided with a rod which passes through the pin and the nipples. A further accessory is provided in the form of a ramrod provided with metal ends pressure-fit and secured to the wood body of the ramrod by some notches that penetrate into the wood of the ramrod.
