I've been looking at uppers here lately and the 223 wylde has caught my eye. From what I can gather it shoots both 223 and 556 but has tighter tolerances so the 223 is still accurate and the 556 round is even more accurate than just having a barrel chambered in 556. I was wandrring how reliable it is with 556, what kind of grain would be good with it. Id like to have a 1/8 twist stainless barrel too. Anyone have any thoughts on these or own one the input would be great as I am just really learning about these types of things, Im not much of an AR guy. Yet.
