Original firing pin and firing pin spring replacement for Mosin Nagant 1891, 1891/30, M38, M44 rifles.

To replace the firing pin and its spring push forward on the bolt handle and pull rearward on the cocking piece, then rotate the cocking piece counter-clockwise 90 degrees.

Using a block of wood, press the firing pin against the wood with downward pressure on the bolt handle and, while maintaining firm pressure downward, unscrew the cocking piece counter-clockwise until it unscrews from the firing pin.

Replace the firing pin with the new one.
