This is an adapter to fit a scope to the the crosman 760 rifle (760B). The scope came with 20mm mounts for picatinny rails and such. However, the crosman 760 has a much smaller 13.4 mm rail. Using a little math I was able to fit the rail snugly and provide a shim that allows me to mount my third party scope.

To use, start this shim along the curve of the rail in the back and slide it to desired position. Then place the unscrew the scope mounts and place over the shim.

Any desired commercial use, please contact me directly.
