I have a Mossberg 835 shotgun with a 21 inch barrell. It is my turkey hunting gun/ home defense gun. Im looking for some way to mount my Fenix TK-10 flash light to the gun. Ive seen the ATI mounts that clip on the barrel or magazine tube but with the short barrel there is not enough room to fit it in. Anyone have any other ideas? It sure would be nice to have a light mount when Im shooting coyotes in the hen house at night.
