Mosin Nagant m91/30
 
hey guys, i disassembled my m91/30. and i accidently turned the screw that adjusts the firing pin. i am not sure if i made shortened it or lengthened it, but i am 100% sure it was not in the same place it was before. is there a way to knowingly adjust the depth of the firing pin back to that way it was before?

sorry for dumb question, just dont want to mess anything up or hurt anybody!


thanks,

ILgun

You can order a dissasembly tool that also is a firing pin measurement tool to correctly set the firing pin back.

Your rifle should have come with a tear drop shaped tools with an open circle on one end a 3 notches on the other. The center notch is a firing pin protrusion gauge. Goggle the proper procedure and use the tool as instructed. Otherwise a gunsmith should be able to adjust it for you in about 5 mins.
Word of caution, too much pin protrusion can cause "slam firing" so do not chamber a round until it is corrected.

Did you get a little tool kit with your mosin? if so the notches on the screwdriver looking multi-tool are the gauges for the firing pin.

The two small notches are the maximum and minimum heights that the striker should protrude from the bolt face. As long as the pin is between the two your good. if you dont have the tool you can use a caliper, the measurements are 0.095" maximum and 0.075" minimum.
heres a good site with lots of info: Collecting and Shooting the Mosin-Nagant 1891/30 - HISTORY
