my wife has a dpms panther. she picked it out. i had to do some mods to get it within reasonable running condition. almost nothing was properly torqued or staked or loctited. i pretty much had to rip it apart so no two pieces were touching then put it back together correctly.
they function out of the box fine for very light range use. but if you plan on running them hard they need a lot of work.
my opinion your better off spending a bit more and getting a better assembled AR15 if you dont know the platform inside and out. they are good buys if you dont mind get your hands a little dirty and re-doing the build.
