Looking for a device to mount a camera, or other device with a similar to quarter inch screw mount to a standard rail system. I'm looking to attach both a camera, and possibly a night vision monocular, to the rails on my M4A1. After a short time searching, and finding one option that seemed cost prohibitive, I came to the conclusion it would be easier to simply ask, as someone surely has had this idea long before I had.

Thanks in advanced for the help guys!
