Description
The Bond Arms Cyclops “Thumper” is a compact, single-shot, break-action derringer chambered in the hard-hitting 50 Action Express cartridge. Part of the Bond Arms Big Bore lineup, the Cyclops pairs a 4.25″ stainless steel barrel with a stainless steel frame, both wearing the rugged Rough & Tumble black finish for a tough, no-nonsense appearance built for serious big-bore work.
Built on a true break-action derringer platform, the Cyclops operates as a single-shot pistol: simply snap the barrel open, load one 50 AE round, and snap the barrel closed. A crossbolt safety and simple fixed sights keep the controls intuitive, while the black extended B6 resin grips provide a secure hold against stout magnum-class recoil. The pistol weighs 28 oz and measures 6.75″ overall, making it compact enough to pack yet heavy enough to comfortably handle full-power 50 AE loads. Right-hand configuration.
Chambered specifically in 50 AE, the Cyclops is intended as a backup or brush pistol for hunters, outdoorsmen, and handgun enthusiasts who want Bond Arms’ compact derringer platform in a more powerful, single-bore cartridge than the typical 45 Colt / 410 Bore two-shot derringer configuration. The single-action-only design echoes the classic derringer layout, but in a beefier single-bore format that lives up to the “Thumper” nickname.
