I just picked one up from JG at the end of June(I might have actually bought there last one ahah) and mine also didn't have much cosmoline on it. I got 2 clips from liberty tree for around 18 bucks including shipping.
Shooting it is both a little rough(im kinda small) but a whole lot of fun, and the ammo so far hasn't been too bad on the wallet(19.99 for 20 Prvi)
Now I just gotta get a bayonet and some surplus ammo to make it more complete.
Have fun and enjoy your new Steyr!
O also this is a good video I found on the bolt disassemble

AT the 7:30 mark is a real good tip if you are having trouble getting the bolt back in place
