My son met a guy that needs $. He want to sell an AR15. Cash in a parking
lot kind of deal. He claims its an accurized (sp) unit that has higher
value. Comes with a military noise suppressor that is supposed to be rare.
Anybody have advice, web sites to read etc. on determining value?

I've seen one on TV but never touched one. And not much of an expert in this
area.
