I just picked up a Smith & Wesson M&P 15-22, was going to get a 10-22, but got pulled into this one... I think it has become my favorite plinking gun! I've run about 500 rounds through it already and it is a blast to shoot, accurate and much cheaper to shoot than my ARs. I can tell that I have become much more proficient using AR style irons already. It looks and feels just like my other AR's and even has a charging handle unlike some of the other AR-22's. I am so glad I didn't go with the 10-22, I have a Rem 597 anyway so I guess close enough. It has shot all of the bulk stuff that I have tried so far, without a hickup. IMO anyone who has an AR and wants to improve their shooting skills with it should consider a 15-22. My kids can't wait until tomorrow when they will get a chance to runs some ammo through it. My .22LR supply is going to take a hit...
