I am going to have to say that the overwhelming majority on here saying that the barrel probably was of legal length and that I was duped are probably right. However, I'm going to forget about the couple hundred dollars lost and chock it up as ignorance that I will never repeat again. It did seem fishy to me too, and probably was a tactic to get the gun for a cheaper price, but at the time I was so worried that I had somehow done something illegal and just wanted to stay away from trouble. Besides, I really don't have any use for an ar-15 other than punching holes in paper with overpriced ammo. And, being that I am just a dumb kid, I'm not going to try to take any legal action about it. In fact I would rather that it WAS a legal rifle and that all is well.
