Bond Arms Cyclops Thumper | .50 AE | 4.25in | BACY-50AE

The Bond Arms Cyclops Thumper is a single-shot, big-bore pistol built around a stainless steel frame and a 4.25″ barrel. It is chambered for .50 Action Express and fitted with B6 extended grips and fixed sights, presented in a Rough & Tumble stainless finish. For a practical optic under $1,000 that pairs well with this platform consider a compact red-dot such as a Holosun 507-series micro sight for fast target acquisition and a low-profile mounting solution. This handgun suits large-caliber field use and heavy-bullet testing at the range.
