Assembly question - bolt action Mannlicher

Hi, I have a question about a Mannlicher-Schonauer M72 carbine. In removing the bolt carrier to "zip tie" the breech area for a safety check, the firing pin assembly became disconnected from the carrier. I now cannot reasemble it as the firing pin is in the "fired" state and won't "cam up" to the carrier. Bascially, I need to charge the firing pin so I can reassemble it, but cannot figure out how to do that out of the carrier and out of the gun.

Does anyone know the trick to this, or another place I can go for advice? I'm really stuck here and have had no success with web searches or finding anyone knowledgable about these models.

Thanks,

Bryan

    If your rifle is the Steyr-Mannlicher Model SL? There are specific reassembly instructions in the book "Bolt Action Rifles", 4th Edition, by de hass and van Zwoll.

    kamerer,

    I hope that I'm understanding your problem.

    You need to remove the bolt from the rifle.

    On the end of the bolt opposite the bolt face are two pieces that work together; (1)the bolt sleeve or shroud and (2)the cocking piece.

    The sleeve surrounds the cocking piece. The cocking piece has a notch or two in it which should be oriented to the bottom of the bolt.

    You need to grab the notched part of the cocking piece carefully but firmly in a vise, pull it away from the bolt, rotate it and engage it in the 'cocked' notch in the end of the bolt. You are working against the firing pin spring which can pretty stiff and powderful so be careful.

    Sometimes it can be helpful to have another pair of hands. If you don't have a vise, you can try using the edge of a wood work bench but again, be careful.

    Best.

    Dear Nononsense,

    Yes, that's the issue. I had deduced this afternoon that a vise to basically manually "cock" or charge the firing pin/"cocking assembly" so I could re-insert it into the bolt was my solution. Since this particular firearm is not one I have worked on/studied before, and I had no manual or instructions, I wanted a better opinion. Clearly you are it! Thanks.

    I have a soft-jawed jeweler's vise I use on/with my handguns and I will do that.

    Thanks again,

    Bryan

    New firearm? (New to you, that is?)..carefully check the "cocking notch" nononsense refers to. With a magnifier. It's a classic wear point on these type rifles. If the ramp is worn, that is, notch is not deep enough, the striker-firing pin assembly will easily snap forward to the fired position. It happened to you. If worn, gunsmithing is necessary to restore the notch to orig. dimensions (usually by welding..adding on metal, then honing/polishing the contact ramp). If you just purchased it, and you find out that what I say in this post has validity, you may consider returning to the place of purchase to discuss options. Hope this helps. Joe
