under 700 is getting tricky
look at S&W's, Bushmaster, and Stag arms

DPMS is a sub division of remington
there known to be of the lower end of the quality IMO
NOT saying there bad, but they are NOT as high of quality as many others out there
accuracy will be MOST likely lesser in a cheaper AR, than a higher one
TO a point
even the HIGH end one's DON"T mean there super accurate, just more reliable, with parts proven to take more abuse
many of the lower end AR's don't have dust covers on them or forward assist

Watch places like Cabela's, Gander MT and like store, they run many sales on better models for under 700
just seen a whole AR kit, with bushmaster, M4's, a case, a few mags, and a sling for $699.99
I am a bigger fan of Stag arms too, they make some nice ar\s for the price point
forearms with a lot of add on possibles, is a VERY hot these days
to me, there more a pain on your hands than needed LOL
you have to remember that , you can later add about anything you want to an AR, with some basic skills and tools

LAST stay away from any of the metal cased .223 ammo, like WOLF and the likes, there known to break a lot of firing pins, the lacure on the cases builds up and ends up causing issues ONLY in AR's\
in AK's and SKS"s they work great
plus all metal cases are harder on receivers on ejection
which again some lower end AR's don't have the deflectors blocks on them
IF you like to build guns, Brownell's just had some super deals on complete Bushmaster lowers, for under 200 bucks, with folding stocks and all, heck of a deal IMO
I grabbed 4 of them LOL
