A muzzle loading firearm having a frame upon which is mounted a centrally bored barrel with a centrally bored plug threadedly fitted into and plugging the breech or rear end of the barrel, with the plug having a rearwardly extending nipple portion over which a cup-shaped percussion cap is placed. An axially movable spring loaded bolt, aligned with the axes of the barrel and plug bores and nipple, has an anvil end arranged to impact against the cap upon actuation of a trigger mechanism, for firing the charge loaded within the barrel through its muzzle. The bolt is locked against axial movement by a safety mechanism, including a rotatable knob, mounted upon the rear end of the bolt, with the knob having a forwardly extending spacer pin arranged to selectively abut a portion on the frame to prevent forward movement of the bolt or to align with and fit into a frame recess of sufficient depth to receive the pin when the bolt moves forwardly against the cap. An openable flash shield normally covers the plug nipple and bolt anvil portions.
