Nobody ever said Colts do anything special. That's not the point. It's a matter of consistency from one rifle to the next, and longevity of parts. It's all the same question. What the OP is wanting is to build a Colt quality AR for less than the price of an LE6920, which isn't possible. My point is if you want Colt quality, then buy a Colt. You can't beat the price no matter how you hash it.
