The only place besides David Condon is Tony Wilcox. His specialty revolves around military firearms, but he does have something sporting on occasion. Not sure what his inventory includes because every time I stopped by on my way home his place of business was closed. Your chances of finding something of interest at Clark Bros. or Greentop are just a notch above proverbial needle in the haystack. I would would visit National Firearms Museum and enjoy DC landmarks and forget Northern Va. gun shops. As mentioned above with exception of few tables VA gun shows are basically expensive flea markets.
