Over many, many years, I have found it very difficult to find a buyer willing to pay me "top dollar" for "collectables (NIB, all correct military/commercial accessories, "paper", etc.) because all my gun sales were forced on me by circumstance, and did not afford me the luxury of waiting out the months to find a buyer who recignized the value of what I had, and then was willing to pay.
So I feel that these were all sold for much less than they were worth. In other words, I could have been shooting them (but keeping them in very good shape) and enjoying them a bit.
So what I am saying is examine the conditions in which you would put one of these up for sale. Also consider that if the AWBan dies, some "desireable and conspicuously protruding" features will be legal again, and this will change the core value of many AR's.
