flames pending !! I just bought the S&WMP15-22 a few weeks ago. I like it because the controls are like my AR. So a lot of stuff I have around here is compatible with it. You can get extra mags at 44MAG.com for $17.95 each. I put a red dot M3 clone with a high mount (for co-witness) on it for $79 from primaryarms.com. That's my .02 but I'm your first reply
