Just giving you a heads up that pretty much any magazine other than the factory, fixed 10 rd. is going to have reliability issues. You can modify the followers in them to make them feed more reliably, but this usually results in the bolt not staying open on the last shot. And the AK mag conversion is a pain in the ass. I have had several SKS's and have modified after-market mags and gotten them nearly 100% reliable, but I have never been able to get one to feed 100% and hold the bolt open on the last shot. The best way is just to buy a bunch of stripper clips and load them up with 10 rounds and use the speed load notch in the bolt like it was intended to be used. But if you are just going to be plinking with it, not relying on it for protection, I guess the aftermarket mags will work for you.
