The rail is held in place by a small metal spring loaded tab. The metal is in the shape of a number
seven (7) the small leg presses against the plastic and holds the rail from escaping; to remove we
need to elevate the metal tab over the plastic so it can slide to the left. You will also notice a small
bead of rubbery glue holding the metal tab down, use a pick or screw driver to scrape this off
making removal easier.
