This is a Manfrotto 322RC2 Joystick camera mount with a LaRue quick disconnect rail adapter that LaRue made specifically for it. They are designed to mount on tripods.

I have a motion detector mounted to the feeder that sends a signal to a chime in the house. When it goes off I carry the gun to the back fence....lock in the quick connect and shoot.
