One 4 * 4 mm cylindrical magnet. I used N52 grade ones.

Assembly

Press the magnet into the hole of the pusher. Apply some glue if it's too loose.

Replace the original parts with these modified parts, the assembly process is exactly the same as the original Gryphon.

The only thing you need to be aware of is the alignment of the gear, the arrow marking on the pinion gear should point straight up when the trigger in not being pressed.
