I have had a few M&P 15 Sports. If you dont need the forward assist or the dust sheild, they are fine.
It is a pretty good gun for plinking and for simply having a cool assault rifle. And the price is tough to beat. I bought a couple last summer, added accessories..and tripled my money this year selling them when the craze took off!
