At a nearby gunshop there were a set of SKS's for sale for $120. I know that's not exactly the most competetive price but what interested me was that these were never fired or used. They were completely coated entirely with cosmolene. They even had a few flakes of cardboard stuck to it. Everything mint and never used. They were that model with that neat little useless grenade launcher. I also noticed they had flip-up night sights which I never knew that SKS's had.

Considering the superb condition of these... should I buy one?

Well, if that's a reasonable price, I better go grab it up. I've heard of people buying them for much cheaper but considering the conidition of it, it's a reasonable price it seems.

SKS newbie here. How hard is it to get replacement parts for them?

Thats a good price. I got mine, unfired, for $169.   Here some places for parts.

Stay away from the detatchable mags.  They're all junk. Stay with the ten round.

I've seen good condition Yugo's go for less, but I've seen a buttload of them go for much more.  $120 sounds like a pretty good deal to me.  I'd snap it up if I were you!!

I dropped 2 bills for mine.  It may have been unfired, but I know it had less than 10 rounds through it if it had been.  It also had 17 pounds of cosmoline in it.  I dropped the mag and pulled the bolt back.  It took about 20 seconds to make it all the way forward with a loud "slurp" sound.    It's due to have the stock smooth sanded and treated with linseed oil.  Doesn't need it, but it'll be even more pretty than it already is.  

Sounds like a deal to me,I would pick it up If I were you.
