Hey Serenity!
I just got a Yugo SKS for Christmas as my first rifle (not counting my 22 and musket) and I have to say, it's a blast! (No pun intended!)
The lack of Chrome lined barrel isnt really a hinder unless A) you are going to be marching around in a hot and humid jungle B) not able to fully clean your rifle after shooting (because you're marching around in a jungle!). I would take Nef's advice about the barrel being pocked and such, and would thoroughly look over the rifle before you purchased it. Mine is in relatively good shape and fun fun to shoot! The rifle grenade attachment is a bit pointless (well, for some
) but it is a neat addition and a good conversation starter! Also, if it is fully cleaned of the cosmoline already, then that is a deal, as I just went through the 3 hour nightmare that is a fully cosmo coated SKS the other day. I wouldnt bump the sks off your list just yet.
Though the Mosin is fun to shoot too...
