Claim:
A muzzle-loading firearm comprising: a barrel having a front end corresponding to a muzzle of the barrel, and a rear end; a breech plug arranged at the rear end of the barrel, said breech plug having a rear end arranged to receive a primer, and a front end; a frame part arranged in correspondence with the rear end of the breech plug; a firing block arranged adjacent to the rear end of the breech plug, said firing block housing a firing pin in a longitudinal firing pin channel of said firing block, whereby the firing pin is arranged displaceable between a front position and a rear position in said firing pin channel; the firing block being slidably connected to the frame part so that said firing block can slide rectilinearly, in a direction substantially perpendicular to a longitudinal axis of the barrel, between a closed position in which the firing block covers the rear end of the breech plug with the firing pin channel aligned with said breech plug, and an open position in which the firing block does not cover the rear end of the breech plug; and a pivotally arranged blocking element arranged so as to selectively block the firing block in its closed position and in its open position, wherein said blocking element comprises an end portion arranged to be inserted in at least one corresponding recess in the firing block so as to block the firing block from sliding, and wherein said at least one recess in the firing block comprises a recess in a leg member of the firing block.
