lol, me too. Obola was just immaculated and all of the black guns were long gone all over the state. I talked to a clerk and he said that he thought he saw one in back...left and brought out a black plastic box with a sig 556 in it. Neither one of us knew anything about it, but I bought it.
As far as basics, functions, it's the same weapon. The problems came in when sig started to make cheap parts and then had shoddy, indifferent craftsmanship and workers. If they would have used the same US oriented setup, but used quality machined parts put on by workers that cared...and management that wanted the preceeding to happen, no one would be talking about how the swiss 55x is better than the american 55x.
