Smith & Wesson MP15 22LR i have been searching for a nice 22 rifle for her, so she can go put a ton of rounds through it. This ended up being the one we bought. Its light, 25rd mag, shots pretty accurate, and has a heavier barrel than the colt we were looking at. This thing is fun as hell to put rounds through. it didnt like Federal American Eagle rounds too much, jammed one every 4 mags or so, but went through remington ammo without a hitch. this thing will accomodate pretty much any AR accessory, grips, stocks, optics, whatever.. should be a great little piece to throw some cool gadgets on.
