I take it you want to sell it but can't because of the stupidass law?
If so, that really sucks then that you got screwed like that.
I could have sworn that way back when, before those laws were passed/enacted, they read that you could sell those firearms/mags out of state, but just couldn't sell them in-state. It's ridiculous that you can't sell them at all just because someone wants to feel good and they'll feel safer with only 15rds as opposed to 16rds or more.
