As long as the SKS was purchased before the high cap ban in 94, who's to say the mag was not all ready in. I am not going to tell them. my SKS had a 30 rd mag , in 1987. And your right who would wan't one. Took mine back out in 1987. Original 10 rd mag faster and easyer to load, with stripper clips. If you buy a SKS pre-ban with a bayonet, you don't have to take it off, just becouse you purchased it after 1994.
