wow this site not used since 2009 that's 6 years. Too bad, all the links to sks manual are no good. Owner of this site should close it down.
Post a new thread asking for SKS manuals in General SKS Discussion, and you will get quite a few replies with links;
Having said that, most of the SKS "Manuals" out there are skimpy at best;
Instead, for in depth info on disassembly and troubleshooting , check the stickys and tutorials here: which are a wealth of information far beyond (and honestly, a lot more useful) than any manual for this particular rifle family.....
