Disregard my daughter's jewelry. That is a 1 1/4" trap pipe connected to the scope. I can't tell you how much it cost since it was a piece that I had laying around. It would normally come in a kit for an "s" trap or maybe a "p". You may have to experiment to find one that fits your scope. I cut it the length that seems to give a decent view through the scope's field of view. The compression fitting holds it on snugly. Attached is a 1-1/2-in x 1-1/4-in PVC Trap Adapter Fitting. The cradle is a 1-1/2 galvanized pipe hanger. I bent the end facing out and cut off the excess. Then used the excess to make the bottom arm of the cradle. In this picture I haven't cut them off. I would recommend using a rubber band to hold the phone securely during recoil. I already had the trap, the adapter was $1.23 and the hanger $.97.
