The Railway sight quickly attaches to Weaver and Picatinny rail style scope mounts. This enables the Railway to be attached to virtually anything! Shotguns, rifles, handguns, revolvers, crossbows, paint ball guns; these are just a few of the applications the Railway has seen. The sight can be easily detached and installed on other weapons, making it the most versatile in the C-MORE line up.
