Description
There are bold guns, and then there is the Bond Arms Cyclops. Chambered in .45-70 Government — a cartridge that dates back to the 1870s and normally calls a lever gun or single-shot rifle home — this break-action pistol packages one of America's great big-bore rounds into a 6.75-inch, 28-ounce derringer-format handgun. It is not subtle, and it is not pretending to be. The Cyclops is part of Bond Arms' Rough Series, and it was purpose-built from the ground up as a dedicated single-shot platform, not a conversion. Bond reinforced the frame at key stress points, lowered the bore axis to better accommodate the .45-70's large rim, and left the space where a second barrel would have been as a solid hunk of stainless steel. That extra mass up front does real work keeping muzzle rise in check.
Why the Cyclops Got Its Own Frame
The reason the Cyclops exists as its own platform instead of a barrel swap is simple engineering. Bond Arms tested big-bore double-barrel configurations earlier on and ran into problems with recoil causing the rebounding hammer to drop on the second barrel. Going single-shot solved that entirely. The result is a beefed-up stainless frame with a single-action trigger, a push-button crossbolt manual safety, and the same left-side barrel release lever that Bond Arms fans will recognize from other models in the lineup. Trigger pull comes in around 7 pounds and operates with a slightly downward motion rather than a straight rearward press — something to be aware of before your first range session. The fixed sights are simple and functional, with a front blade and rear notch integrated into the barrel hinge.
Built to Handle the Recoil, Not Hide From It
Bond Arms ships the Cyclops with their B6 extended resin grip specifically because it can take a beating that would crack laminated hardwood. The grip is sized to support all four fingers and fill the hand more completely than a traditional derringer grip, which genuinely helps manage the sharp recoil that comes with running a rifle cartridge through a short-barreled handgun. Multiple reviewers found subsonic .45-70 loads to be the most manageable option out of this platform. Bond Arms recommends loads with muzzle velocities under 1,500 fps. The Cyclops is also a great conversation starter at the range — one of those guns that draws a crowd every single time it comes out of the bag.
The barrel features laser-engraved artwork on the flat muzzle face, a life-sized .45-70 cartridge engraving on the left side, and the words "Verify Clear" inside the chamber when the action is open. Worth noting: the Cyclops barrel is not interchangeable with other Bond Arms frames like the Hand Cannon, Stinger, or Stinger RS. And the barrel has no extractor — spent cases are removed by hand from the chamber after breaking the action open.

Frequently Asked Questions
Is the Bond Arms Cyclops barrel interchangeable with other Bond Arms pistols?
No. The Cyclops was built on a dedicated frame that is not compatible with barrels from other Bond Arms platforms like the Hand Cannon, Stinger, or Stinger RS. Bond Arms engineered an entirely new frame for the Cyclops to handle the larger rim diameter of the .45-70 cartridge and the added stress of the round. The good news is that the Cyclops frame should accept future big-bore barrel offerings as Bond Arms expands the Cyclops series.
Does the Cyclops have an extractor for removing spent cases?
No, the Bond Arms Cyclops does not have an extractor. After firing, you open the action using the barrel release lever on the left side of the frame, and the spent case must be removed by hand from the chamber. Bond Arms notes this on the product page, so it is worth knowing before your first range trip. Most .45-70 cases come out easily enough, though hotter loads can cause occasional sticky extraction due to heat expansion.
What kind of .45-70 ammo works best in the Cyclops?
Bond Arms recommends loads with muzzle velocities under 1,500 fps. Subsonic and lower-pressure .45-70 rounds like Hornady's SUB-X line are widely considered the most manageable out of the 4.25-inch barrel and tend to give the best balance of performance and shootability. Heavier, hotter loads such as Buffalo Bore hard-cast rounds will fire fine mechanically, but the recoil goes from stout to genuinely brutal in a hurry. Keep your load selection practical unless punishment is the point.
How does the Cyclops trigger work, and why is it different?
The Cyclops uses a single-action trigger, meaning the hammer must be manually cocked before firing. The trigger pull is approximately 7 pounds, which is heavier than most semi-autos. What catches people off guard is that the trigger requires a slight downward-and-rearward press rather than a straight rearward pull — this is a function of the pivot geometry used in Bond Arms' derringer-style trigger design. It takes a little getting used to, but it is documented in the owner's manual and becomes second nature with practice.
What holsters fit the Bond Arms Cyclops?
Because the Cyclops shares the same exterior profile as Bond Arms' Snake Slayer double-barrel pistol, most holsters made for the Snake Slayer will also accommodate the Cyclops. Several leather and synthetic OWB holsters from Etsy makers and aftermarket brands have been confirmed to fit. Bond Arms also sells a dedicated premium leather Cyclops holster that is available separately or as part of a satin finish package.
Who is the Bond Arms Cyclops really made for?
This is a gun for collectors, experienced big-bore enthusiasts, and people who genuinely enjoy the spectacle of a .45-70 going off in a small handgun. It is not a beginner's pistol, and it is not built for high round counts. It is an attention-getter at the range, a bucket-list item for fans of the .45-70 cartridge, and a well-built piece of American craftsmanship from a company that has been making serious derringers in Granbury, Texas for decades.
