A few days ago I went out and purchased a brand new M&P15-22 after hearing good things about them. I am pleased to say that I can practice on the AR platform for a fraction of the cost. I ran well over 600 rounds of the 36 grain Federal CHAMPION 525 round value boxes of .22LR ammunition and not one single malfunction. It was shooting a bit low for me right out of the box but I adjusted the sights a bit and it hit almost point of aim at 25 yards.The Ruger 10/22 I had would jam constantly on this stuff. Accuracy exceeded my expectations and when I do eventually buy another .223 AR-15 I think I'll have practiced on the M&P15-22 enough to know how to run the center-fire counterpart really well.
I highly recommend this rifle to any AR-15 fan or someone looking to get a fun gun to shoot that won't break the bank!
