What’s Included
- Bond Arms Cyclops Thumper .50 AE single-shot pistol
The Cyclops Thumper is purpose-built for the .50 AE cartridge and holds one round, pairing a heavy-profile, single-bore barrel with a solid stainless steel frame. This configuration focuses on strength and straightforward function in a compact format.
The Rough-series style matte stainless finish on the frame and receiver provides a consistent, non-reflective appearance. Fixed sights include an integral front blade and a fixed rear notch for a durable, no-adjustment setup.
Controls are simple and robust: a left-side frame latch opens the action, an exposed spur hammer readies the shot, and a cross-bolt safety provides an added safeguard. The smooth, curved trigger delivers a clean pull appropriate for this single-action design.
Ergonomics are enhanced by black checkered rubber/resin extended B6-style grips that help manage the big-bore chambering. At 6.75 inches overall and about 28 oz, this USA-made pistol balances portability with stout construction. MSRP is $649.
