Description
There are guns you buy because you need them, and then there is the Bond Arms Cyclops. This is the only single-shot derringer Bond Arms makes, and there is a good reason for that: it chambers the .45-70 Government, a rifle cartridge that has been dropping big game since 1873. Fans asked Bond Arms for years to build a derringer around this round, and the Cyclops is the answer. This package version, model BACYP, adds a fitted leather holster and wears a high polished satin stainless finish with the Cyclops logo on the right side of the barrel while the left side and muzzle stay clean and unmarked.
How the Cyclops Tames a Rifle Round
Bond Arms did not just stuff a big chamber into a small gun and call it a day. The 4.25 inch stainless barrel is bored as a single shot, so all the steel that would normally go to a second chamber stays put, adding weight below the bore and dropping the bore axis. At 28 ounces, the Cyclops soaks up recoil far better than you would expect from a 6.75 inch pistol. The extended B6 resin grips fill the hand properly and hold up to heavy recoil better than laminate wood, and the frame includes a trigger guard, crossbolt safety, fixed sights, and the familiar left-side barrel release.
Bond Arms Cyclops .45-70 at the Range
Let's be clear, this thing is a blast to shoot in every sense. Range days with the Cyclops tend to draw a crowd, and the recoil is stout but genuinely controllable thanks to the weight and grip design. Standard factory .45-70 loads like 325 grain flex-tip ammo run well through the short barrel and still deliver serious energy. Break it open, drop in a round, cock the hammer, and enjoy one very memorable trigger pull.
A Big Bore Piece Worth Owning
Between the engraved barrel, the included leather holster, and the sheer novelty of a palm-sized .45-70, the Cyclops earns its spot in any collection. It is a conversation starter, a woods companion, and one of the most entertaining guns Bond Arms has ever built.

Frequently Asked Questions
How bad is the recoil on the Bond Arms Cyclops in .45-70?
It is a handful, no question, but it is more manageable than most people expect. The 28 ounce weight, low bore axis from the bored-out single-shot barrel, and the extended B6 resin grips all work together to soak up recoil. Most folks come away grinning and asking to shoot it again.
Does this Bond Arms Cyclops model come with a holster?
Yes, this specific package version (MPN BACYP) includes a leather holster in the box. Since the Cyclops shares its exterior profile with the Snake Slayer, most holsters built for that model will also fit if you want other carry options down the road.
Are Cyclops barrels interchangeable with other Bond Arms barrels?
The Cyclops is built on the standard Bond Arms frame, but the .45-70 barrel is not interchangeable with barrels made for the Stinger, Stinger RS, or Hand Cannon frames. Also note the Cyclops barrel does not use an extractor, so you will pluck spent cases out by hand after firing.
What .45-70 ammo works best in the Cyclops?
Standard pressure factory .45-70 loads are the way to go. Flex-tip rounds in the 325 grain range run reliably and still produce serious muzzle energy out of the 4.25 inch barrel. Skip the hot loads made for modern lever guns, since they add punishment without much practical benefit in a barrel this short.
