There was a guy in Chantilly selling a rifle for $1000. He called it a Bushmaster AR15 but it looked more like a Galil or an ar 18o. I told him I thought it might be a 180 but he said no it takes AR mags so it's an ar. OK, I wasn't going to argue with him but if I'd had the spare grand in me pocket it would have come home with me.
The lower looked stamped but I didn't look too close. It was NOT a standard ar15 lower.
