Airsoft AK-47 Redesigned Selector Gear

i got sick and tired of that stupid screw coming out all the time, so i redesigned the gear arm to remove the rotational force that was getting applied to it. after 14 design attempts i made one that works (at least in my gun)

WARNING: you will need to drill out the gearbox's screw hole with a 1/4" drill bit, and once you do that there is no going back.

note: there is some support around the hole for the trigger lock that will need to be cut off.
