bought the tactical kit and was trying to use it on a .22 revolver by inserting the flexable rod through the barrell and attaching the brush. When the brush is attached to the solid part (brass) of the rod AND the connection piece of the brush, it is longer than the crane opening? There is no way to get it through the breech of the bore without bending the brass parts. I see that they advertise for PISTOLS but say nothing about revolvers. Has anyone else made the assumption that the otis kit was made for revolvers?
