No. 

Bond Arms does not, and will not, manufacture rimfire barrels as an accessory for our derringers.

Rimfire barrels must be matched to each frame individually and tested for a proper fit and function.  With the extremely tight tolerances dealing with a small firing pin and a small rimfire target, Bond cannot guarantee that an aftermarket rimfire barrel will properly function on a customer's frame.

Because Bond Arms cannot guarantee a high success rate with aftermarket rimfire barrels, we will not be selling them outside of a matched frame.
