Quoted: Thx for link, The $150 price tag was on a yugo they got in about 5 of them so there going to hold one back for me. It looks like ill need to learn the gas system is there a specific book I should look for or should the manual discuss it? This cosmoline substance how would I go about cleaning it out of the the firing pin channel, Ive seen the guides to disasemble them but what should I look for and how would I tell where it is, is it just like a thick grease or preservant?

The bolt is pretty difficult to get open. Apparently you really have to whack the pin out. I didn't get mine open and decided not to resort to extreme whacking and damage my bolt.
I found the following very successful:
1) Spray thoroughly with break-cleaner or gun-scrubber and clean off as much cosmo as you can with a paper-towel and/or brush.
2) Let the entire bolt soak in Hoppes Solvent for an hour, then dry it off with a paper-towel.
That'll do it for most bolts. If you still have cosmo oozing out of the bolt, you can do the additional steps:
3) Put the bolt in the oven at 150-200 degrees Fahrenheit (cosmo has a low melting temperature and should drip off, be careful of any oven wires)
4) Let it soak in Hoppes Solvent for another hour, then dry it off with a paper-towel.
The goal is to have your firing pin move freely. If you hold it up or down, the pin should fall up or down by gravity alone. It should also be able to shake around freely. Keep your firing pin bone-dry. Don't oil it.
