don't go with the prices off the web site they are usually the msrp and not what they can actually be had for. they would all serve you well. the dpms would probally be the best value because they are the lowest in price that i have seen at the shops and various places i have seen them for sale. they are great guns and in my experience are the least expensive of the three you named. there has been alot of new rra ar owners as of late and there are lots of great reviews. i can say that there replacement triggers are sweet as can be and no matter what ar you end up with it needs a rra trigger! i have a bushmaster, so does my dad, between the two of us we have owned 5 and they have all been great to us so i can really only report on them, but i have no issues, with them, they shoot godd and they are reliable. i am very happy with my ar the way it is set up and my dad's as well even though they are different in many ways. i know all the above companies make fine firearms with what little experience i have with them, but i can say without a doubt that the bushmasters are good to go and i know for sure that they will serve you well. i have fired all tyoes of ammo through them from winchester 5.56, lake city m855, wolf 55gr fmj, 62gr hp's, umc 55gr, barnaul and they have all functioned and performed well.
