NFlightCam Aviation Surface Spud for Billet Mount Adapters we designed the filter toPlease note: We discontinued the Billet Mount and replaced it with our Ball Head Mount. This spud is compatible with the old, discontinued mount, so it should only be ordered if you purchased a Billet Mount previously. With this rock solid design, any #6, #8, or #10 machine screw becomes a camera mounting point. Simply remove the screw and install the spud with a longer screw, and you have a camera hard point for the Nflightcam Exterior Billet Mount.
