The compliance kits I had seen for the SKS all included one mag and a new stock and ran around $150. I think Tapco makes one of the kits I was looking at. Do you have a source of where you were getting all of your US made parts for $80? The local price for an SKS is right around $200-$250 here. Even at $200 you then are at $350 to take US made mags which are mainly 20 rounders. The SKS-D or whatever model it is that takes AK mags are running more than base model AKs do around here. I would be seriously worried about buying a felony by buying an SKS from a store that takes mags for 3/5 the price of an AK. I highly doubt it is an SKS-D and if it is it is a good deal, at least with where prices are around here. As hard as it may be to believe a lot of shops don't realize that just because the mags are legal and the rifles are legal that you can't slap the two together with no other modifications legally. Even if you do get an SKS that takes hi caps, unless it is a model that takes AK mags there have been tons of problems with them feeding. I know the ones I have shot wouldn't feed if there were more than 20 rounds in the 30 round mag. If reliable 30 round mags are a need then I still don't see going away from the AK unless you get a good deal on an SKS-D
