The Selector Plate sits on the external of the gearbox, and is a relatively easy component to access. They generally have a Copper contact on the side which can be worn out with time, so any Selector Issues could be resolved with a new one. If you're looking to lock your Replica to Single Shot then this part is easily modified by cutting out a small piece to avoid actuating the 'Full Auto' switch that sticks out of the Gearbox. If you're going to attempt this modification it would be a good idea to have a spare on standby to restore your Full Auto function, or just in-case you make a mistake during install or modification.
