I bought a Bushmaster 16in A2 post ban a few months ago. I have not fired it (hectic move, new job, kids, typical BS) I have decided I now want to build a pre ban.  Whats a fair price for this weapon?  I bought it at an gun show form a local dealer.  It is unfired except for the factory test.  The ONLY thing that coupd be considered a blemish is that mags have been inserted and removed a few times, as it was on display for a few hours. Comes with all the usual extras (sling, case, etc) Any offers?
