What is the biggest firearm flop you have ever seen

[BLACKHAWKNJ]

I distinguish between business flops-Bren Ten, Automag, AMT, U.S. Arms/United Sporting Arms (the Abilene, the Seville ),other companies that were underfinanced or run by people who were gun people but not businessmen, design flops, as have been named, and ones that simply filled no niche or market demand.
