Every AR15 that I know of is built to Mil Spec. Whether it is a lowly "standard" AR or one of the "premium" gotta have AR's. They are all Mil-Spec. Mil-spec is a drawing.
The "premium" AR's hold no special attraction to me.
Yeah. 100% incorrect like others have said. DPMS is fine for plinking. Wouldn't bet someone's life on one. I 2nd whoever said to get a BCM upper and a cheap lower. $79 Palmetto State Armory lower is a bargain at the price. If you manage to snag one during their frequent $50 sale's, it's even more amazing. I've bought ~5 or 6 of them.
