I found an old beat to crap Western Auto (Springfield No 5) and took it apart painted all the metal flat black and the wood olive green with a 2X BSA pistol scope mounted on the barrel like a scout scope. and sighted it in with CB longs. Great little gun. We knick named it CDG (Click Ding Giggle) When I would take it out to the range others would try it and all you would hear is the click of the striker, the ding of it CB hitting a gong, and everyone who shot it would pick thier head off of the gun look at it and giggle, then ask to shoot it again.
Works real well to keep rabbits, moles, ground squirrels, and rattle snakes out of the garden / yard.
