I have an old MrodAir CP-1M Co2 pistol I'd like to start using in the basement. I also have a DFL Tanto I use on my DreamLine. I would like to find a slip-on (fasten with grub screws) adapter for a 10mm barrel that will allow me to use the front sight with the Tanto and maybe reduce the noise a little. Anyone got a lead on something like this from a reputable source?
