So I have a m96/38. Long story short version, the firing pin broke while firing it during it's first range session (possible head space problem it pierced a primer) and it and the cocking piece departed the bolt shroud (shooting glasses ARE your friend) So I purchased a new firing pin and surplus never issued cocking piece. Everything looks OK but I suppose the replacement pin could be out of spec.
For the life of me I cannot get the cocking piece to turn on the firing pin when its all compressed for reassembly. The questions are A. Cocking piece It is supposed turn on 1/2 turn in either direction during reassembly right? B. This cocking piece while Swedish crown stamped is not serial #'d. Was this piece hand fitted in some way? I'm feeling dumb here but thought I'd see if anyone had any ideas... Thanks MR B. |

A 90 degree turn, not 180. Try doing the assembly without the firing pin spring until you get the parts to go together smoothly. It is entirely possibly that hand-fitting is required...... HOWEVER.... You are supposing too much about headspace being a possible cause. You're also supposing too much about the new firing pin being out of spec. Where did you get the firing pin? I ask because there are next to none original Swedish-made firing pins in the U.S. Those from one of the larger parts houses are REPRODUCTIONS without being revealed as being reproductions so "out of spec" could be the problem except you're having difficulty discerning a quarter-turn with a half-turn. I'd suggest taking it to a qualified gunsmith. Here's another thought. You have the broken firing pin, yes? You have dial calipers? Compare the lug and diameters on each of the 2 firing pins, the broken one and the new one. What's wrong with the old cocking piece? Why replace it? Dutch |

Yeah Dutch the firing pin is a aftermarket..from GPC , cocking piece was stuck on the end of the fractured firing pin and I couldn't get it off. It is long gone. The pin fractured between one of the milled grooves on the rear.. And as the pin won't turn at all I've got to assume something's not right. I mean the mauser isn't that closely machined.
