Today while in the garage I decided to fabricate a peep for my Crosman 101. It's very crude... Made out of old hose clamp and a nut. It works great though. At this time the nut is affixed with gorilla super glue. I might use JB weld or something like that. I am I open to suggestions on improvement.
Yup a rear sight is good to have and they are so often missing on the old guns. A bit more werq but a couple more ways to do things in the links below. Or you can put a small piece of metal bent at a 90 deg angle on top of your base with an aperature hole drilled through it in your choice of sizes.
