SubGunFan said:The process is easy. Just pay attention to what you are doing........
With the bolt closed (all the way forward), hold your thumb on the end cap with strong force. Push the big retainer pin up from the bottom and all the way out (KEEP pressure on the end cap because now only your thumb is holding the spring force). Now slowly ease your thumb's pressure on the end cap. The cap will pop off exposing the recoil spring. Remove the end cap and recoil spring. Now be careful tilting the gun too quickly as the bolt will now freely slide back. Hold the bolt handle and slide the bolt all the way to the rear. In the rear position you can put out the bolt handle. Now slowly tilt the muzzle up and the bolt will slide out. This completes field stripping the S&W 76. Assembly is just reversing this process (with making sure the recoil spring goes all the way into the hole in the bolt before installing the end cap and pin).
For more info...... please post a picture of your S&W 76.

I was able to pick up five Suomi mags at a gun show and proceeded to try them. None worked (failure to feed) and then I stumbled on this site. First - Thanks for all the help guys. I dremeled and hand filed the top button on the mags and they worked great. Fed fine.
Next problem was, it didn't go bang! very light (if at all) primer hits. I used the disassembly instructions listed here - and at first I couldn't get my pin out either, but found I wasn't pushing on the end cap enough. I think you have to take the spring pressure off so the pin will come out. Once I did it, the second time was a piece of cake.
Found the firing pin was bent slightly near the end. I got it straight and took off some of the burr that had formed, and so far only tried it with primered bras. At least the primers go off now. Going to the range tomorrow.
Any one know of a source for a new firing pin assembly? Maybe a new bolt as well? Might want to have some spare parts, just in case. Oh, and can someone pooint me to the folding stock rework instructions? I saw them once before, but now can't seem to locate them.
Thanks.

Get an AR-15 firing pin and thread it. Drill out the 760 bolt with a hole just large enough to fit the AR-15 pin. Thread the hole you just drilled. Cut the AR-15 pin and thread it to match the hole in the bolt. You now have a replaceable 760 firing pin.
