Mosin bolt firing pin protrusion
I followed the bolt disassembly and assembly instructions from Surplus Rifle and everything seemed clear enough, however...can't really get the jist of how to increase or decrease firing pin protrusion. I have the correct calibration tool that represents the 75 for lowest setting and 95 for highest. I checked it and am pretty certain that the pin is in specification already, but it would be good to know how to change it if ever need be. Maybe I'm just missing something...
