Just joined here and have a question. My wife just bought me the M&P 15-22 for Christmas(a huge surprise). I had mentioned I liked the M&P sport before. The problem is, she went to the shop, with no idea except it was a rifle and it was and M&P. She either misunderstood or was lead to believe that there were only two models, the 15-22 and the military type up to $1900. I don't know if the guy was out of the sport and wanted to sell the .22 or what. I would like to think it was just miscommunication. Anyway, she bought the .22. After looking at this site, alot of people seem to love the .22. Now the question, keep the .22 or try to take it back to get the sport? Bless my wife's heart, I would like to keep it because she tried so hard. Just looking for some opinions from people who have had these. Thanks.
