Pardon my ignorance, but I'm new to all this. I know Maryland restricts AR magazine capacity to ten rounds, that it is illegal to sell higher capacity AR mags here in the state. My question is: is it illegal to own one? Reason being I found a couple of old milsurp 20's I had from 30+ years ago. Should I dispose of them quietly or just keep them in a drawer for a "rainy day"? What happens if perchance I'm caught with them?
