Love my M&P 15-22. Cheap bulk ammo from Wallymart, the picatinny rails hold everything laser/scope/bipod and it always gets looks when I take it out (that and whenever I empty a 25 round mag in under 10 seconds.) So much fun. I can't say anything bad about it really, accept the first 500 rounds were a little rough, and trying out about 6 different brands of ammo before settling on the federal 550 box. The next 2500 rounds have been near flawless.
