americanrifleman.org is an NRA publication. So they can’t go naming the Remington R51, Taurus carbine or Chiappa Rhino as Firearm Ideas That Failed. Instead they point the fickle finger of fate at the Model 1917 Browning Automatic Rifle (“one can only speculate on why its inventor chose to give his rifle the capability of both semi-automatic and manual operation”), the MBA Gyrojet Pistol and Rifle (“rather than firing ammunition of conventional design, it used a rocket”) and the Daisy/Heddon V/L Rifle (“piston-driven air rifle designed to handle caseless ammunition”). Setting aside these evolutionary dead ends, what gun or guns failed you? What guns or guns didn’t work, broke or simply proved to be not your cup of tea – in a big way?
