The DPMS A-15, the SAR-1, the Romanian SKS and the Yugoslavian SKS rifles are all worth considerably more. Several others have increased a little.
Oddly, Beretta 92FS pistols do not appear to have increased very much. Subjectively, they are my favorite 9mm pistol, and my regular carry pistol. Objectively, they are a truly outstanding, classic pistol by any measure. Maybe there are too many of them, and of course they are made of real metal rather than popular plastic -- sort of like saying that unlike a Big Mac, a Bookbinder's classic hoagie doesn't come in a foam box and taste like cat vomit.
I went to a fairly big show today and saw a few, though not many, 92FS pistols, and the prices had increased only about $50 from last year.
Revolvers have hardly budged. That's why I traded some appreciated autoloaders for some unappreciated vintage Colt double action revolvers, recently. Those things are about to pop, and a trade like that is the same as buying them at deep discount.
Milsurp rifles have crept upward a little, more a function of supply dwindling than of regulatory fears. I was surprised to find NO guns for under $100 at the show (except a beater $50 BP ball and nipple), unless they all sold yesterday. Even a pair of Lorcins were priced at $99 each plus tax. Not so many years ago you could obtain decent milsurp rifles for well under $100 -- six Turks for a hundred from Century -- and cheap .22 rifles were $50.
