I need some advice. I just purchased a Olympic Arms AR used from a local gunshop. It has the FIRSH handguards on it and a stainless barrel. Its a flatop 16 inch barrel with a magpul collapsable stock and grip. I paid 650 for it. I pulled it all apart and it doesnt look like it was shot that much. The lower is dated from 2006 though. It has a standard front sight post but flip up rear sight. The thing shoots excellent and I have ran about 500 rds of american eagle through with no failures. Did i get a good deal?
