Back in the shop looking for something to do....found my old Gamo scope 3-9x40 with a broken windage turret. Remembered I had some PVC drain pipe around almost the right id. With the help of some black duct tape and cutting a piece of pipe to get the eye relief. Cobbled it all together and I have a pretty good spotter. Once you adjust for eye relief and secure the pipe it is in focus right away. Works for me
