I bought an M&P 15 Sport early this year and love it. And today, I bought an M&P 15-22-A1. Great little gun. Both of them keep my Armalite M15A2 company.
If you own one of these and a ban makes it into law, you will not be affected... unless something far more sinister is added to the law. So yes, you can take it to the range and do as you wish.
