Well... I found a lower that I liked. I really like the look of the collapsable stocks. And it's DPMS.

As for the upper, I'd like this AR to be versatile likeI said before. I'd like it to be able to use it for varmints or predators. Is the 16 inch barrel really pushing it for accuracy? Would a 18 inch or 20 inch be a lot better decision?

^If you scroll to the second and third from the bottom, there are 2 20 inch barrels. There are also a couple of 16" barrels near the top. All of which are in the mid $300 range, which I like.
