just a tip, go ahead and order you some stripper clips probrably 20 or more, a sight adjustment tool, and a gas tube cleaning tool. a Sling(if the gun didnt come with one) a buttstock cleaning kit (if it was missing, alot of SKS's dont have them in anymore) and a broken shell extractor (just in case, ive only used mine 1 time) and be prepared to spend a couple of hours getting the cosmoline off if it was covered in it, most gun shops just wipe it off and stick it on the shelf, the inside is more than likely covered. Then get a couple of thousand rounds of 7.62x39 because SKS's are a addicive toy, hell i bought my first one (a norinco) 2 years ago, and now have a 55 TULA, the Norinco, a yugo 59, and a yugo 59/66, and i am wanting to get an Albanian. like i said its an addiction, i hardly ever shoot my 2 AR-15's anymore, i just take an SKS or two, and maybe my VEPR to the range and shoot all day and it doesnt cost me 100 dollars in ammo, and are ALOT easier to clean up than an AR.
As far as the AK goes, if you have a little extra to spend, get a VEPR, they are built on the RPK reciver and run FLAWLESSLY, plus are ALOT more accurite than the WASR's or SAR 1 or 2. I love mine, i payed a little less than 600 for it, but it was worth every penny!!!
