Hey guys well yesterday I found out my dad bought another gun without telling me

. When he told me it was an sks I was both happy and displeased because we had talked about it for a while. Anyway I was displeased because I know the 922r compliant law is complicated and I know he is going to want to put tapco polymer mags on it. So my problem is will putting the tapco 10 round mags on the sks make it in violation of 922r or will it be fine and nothing to worry about? Thanks for any light you can shine on the situation.
