Bond Arms Barrel Features The Bond Arms Barrel is chambered in 10mm and measures 3.5 inches in length giving compatible Bond Arms derringers a new caliber option without purchasing an entirely new firearm. Finished in stainless steel the barrel resists corrosion from regular handling and exposure to the elements keeping it looking new with minimal maintenance. Bond Arms barrels are built to the same exacting tolerances as the company s complete derringers ensuring proper fit and reliable function once installed. Swapping barrels is one of the signature features of the Bond Arms platform letting owners adapt a single frame to multiple calibers. Because Bond Arms derringers are designed around an interchangeable barrel system this 10mm barrel can be swapped onto a compatible frame without gunsmithing giving owners an affordable way to expand their options. The 3.5 inch length keeps the derringer compact and easy to carry while still delivering usable velocity from the 10mm cartridge. Stainless steel construction also simplifies cleaning after firing since the finish stands up well to powder residue and moisture. Bond Arms owners looking to add a 10mm option to their derringer will find this barrel a straightforward upgrade available for sale at GrabAGun.
