Not to my face, as such. I do, however, own a couple Bushmaster AR's and I rarely see anything but derision for the brand on the web anymore, especially since the debut of The Chart. I put the carbine together in the mid-90's and the 24" rifle a few years later using nothing but Bushmaster components. I've shot the hell out of both of them in the ensuing years with nary a bobble. Sights aren't canted. Finish isn't purplish. Gas keys haven't worked themselves loose.
I also remember back in the 90's when I owned a S&W 3rd generation auto (a 4566) with which I was very happy that teh intertoobz regarded them with scorn. Glocks were all the rage at the time and the 3rd gen S&W autos just weren't kewel enough. I guess it was because Tommy Lee Jones didn't carry one in a movie. Anyway, a friend of mine had alway coveted my 4566. He went Above and Beyond the Call of Friendship during a very ugly divorce I endured and, as a gesture of thanks, I traded him my 4566 for a Glock 19. I sold or traded the Glock off pretty shortly thereafter; they don't fit me and never have. I missed that 4566 so much that I bought one on Gunbroker the other night. 3rd generation autos have apparently been rehabilitated since the 90's. Prices, while not crazy high, indicate they've held their value much better than Glocks of the same vintage.
