Where do I start.............
I hate most products of Norinco,Polytech, Llama, Jennings, Hi-Point, Taurus, Rossi, and other poor quality firearms manufacturers
I dislike Smith & Wesson semi-autos, Glock Tupperware, Ruger Handguns - poor ergonomics - all over built, the highly over-rated Ruger Mini-14, modern Walther handguns, the cheaply made Mossberg 500/590 with a POS safety, anything with "SKS" in the nomenclature, Savage Arms, and most "traditional" hunting weapons - especially anything lever-action.
I do like SIG-SAUER handguns, Colt AR-15 variants, Bushmaster AR-15's, Smith and Wesson revolvers, Remington 870 shotguns and Remington rifles, most Steyr rifles, Heckler and Koch, Fabrique Nationale ( FAL's, FNC, MAG-58 and the Minimi (M249) ), the Ruger 10/22, most European or Russian manufactured Kalashnikovs, General Electric mini-guns, SACO manufacured MK-19's, all Browning designed machine guns,and other quality firearms designers...
