Key Features
- 4.25″ Barrel Length — This barrel length gives you enough sight radius for accurate shooting while keeping the gun compact enough for a range bag or nightstand drawer. The single-shot break action locks up tight, so you get consistent accuracy round after round.
- Stainless Steel Construction — Stainless steel means you don't have to baby this gun. It shrugs off humidity, sweat, and the occasional rain shower, making it a low-maintenance addition to any collection. The Rough & Tumble satin finish hides holster wear and keeps it looking good for years.
- B6 Extended Resin Grips — These grips fill your hand better than the standard derringer-style stocks. You'll feel less recoil and get a more natural point of aim, which is important when you're shooting a cartridge as stout as the .50 AE.
- Single-Shot Break Action — Simple, reliable, and easy to clean. There's no magazine to lose, no slide to rack, and no complex mechanism to malfunction. You load one round, close the barrel, and fire. It's as straightforward as a handgun can be.
- Chambered in .50 Action Express — The .50 AE is a proven big-bore cartridge that delivers serious energy. In a single-shot handgun, it's a joy to shoot for experienced shooters who appreciate power and precision. It's also a fantastic conversation starter at the range.
Who It's For
The Bond Arms Cyclops is built for the shooter who already has a rack of 9mms and .45s and wants something different. It's for the collector who appreciates the craftsmanship of a well-made single-shot, and for the handgun hunter who wants a compact backup or a fun gun to pop steel with. If you like the idea of a big thumper that fits in a small package, this is your wheelhouse.
Pros & Cons
- Pro: Rock-solid stainless construction that will outlast most polymer handguns. The Rough & Tumble finish is tough as nails.
- Pro: Extremely compact and easy to store or carry. No magazine means one less thing to lose.
- Con: Single-shot capacity means you have to reload after every round. This isn't a defensive gun for high-threat situations; it's a range toy and collector's piece.
- Con: Recoil is stout. The .50 AE in a 24-ounce handgun will get your attention. It's not for recoil-sensitive shooters or beginners.
