I can 100% guarantee that Bushmaster, DPMS, Bravo Company, LaRue or Noveske rifles all share some of the same parts whether they will admit it or not; only the uninformed try to convince themselves of the opposite.....
I'm fully aware of that, that's why I said I'd buy parts from Delton. However, just like a lot of engine builders might buy their parts from the same warehouse, one is a lot more careful during assembly, and actually CHECKS parts to makes sure they are in spec, and rejects them if they are not. In THAT regard, their can be a huge difference in AR's. And with barrels, like optics, you get what you pay for.
