Bond Arms Cyclops Accessory Barrel 45-70 Gov'T 4.25" Rough Matte

The Bond Arms Cyclops Accessory Barrel in 45-70 Government gives you the flexibility to swap calibers without buying a whole new derringer. This 4.25" rough matte barrel lets you shoot one of the most punishing cartridges available in a compact platform—perfect if you're looking to maximize the stopping power of a backup gun or want a genuine brush gun in derringer form. The rough matte finish is purely functional: it cuts glare and won't snag on clothing or gear.

What sets this barrel apart is its stripped aesthetic. Unlike some manufacturer barrels, the Cyclops barrel comes without decorative laser engraving on the left side or muzzle. That means you start with a clean slate—whether you want to add your own custom engraving to make it truly yours, or you prefer to keep it utilitarian and unmarked. Either way, you're not paying for cosmetic work you don't want.

Accessory barrels are a core feature of the Bond Arms platform. If you already own a Cyclops, picking up an extra barrel in a different caliber is one of the smartest ways to expand your gun's versatility. The 45-70 Government is a serious choice for hunters and shooters who demand maximum power in a small package.

Specifications

Frequently Asked Questions

What Bond Arms gun does this barrel fit?

This accessory barrel is designed for Bond Arms Cyclops derringers. Confirm compatibility with your specific model before ordering.

Can I customize the barrel after I get it?

Yes. The barrel ships without any laser engraving, giving you a blank canvas if you want to add custom work—your initials, a date, a callsign, or whatever you prefer. You can also leave it unmarked if you like the clean, no-frills look.

Why would I buy an accessory barrel instead of a whole new gun?

Swapping barrels lets you own multiple calibers in one gun. If you already have a Cyclops in another caliber, adding this 45-70 barrel gives you the power of a larger cartridge in the same compact frame—without the cost and carry weight of a second derringer.

What finish is on this barrel?

The barrel features a rough matte finish, which minimizes glare and resists fingerprints and minor wear better than polished surfaces.
