Point the barrel of the device to the left, screw side up. Remove the two 8 mm Phillips head screws (the top two) holding the device slide together.

Keep the device in the same position, remove the three 10 mm Phillips head screws from the bottom of the device slide.

Once all screws are removed, carefully separate the two halves of the device slide and put them aside.

Be sure to keep track of which screws correspond to the correct holes.
