I agree with hdwhit, the S&W Sport II is/was the best buy out there. It wasn't meant to be 'mil spec' or top tier,but a solid, reliable economical entry level AR style.
It seems more entry level ARs are on the market, but the more they get, the more expensive they become and miss the point.
The Sport hits a home run for the 'entry' market. Come to think of it, it's a pretty good all around AR.
