This step is going to cover some of the unique parts of the G&GM-14.

The first part people notice is the unique Anti-reversal latch. This piece can be pulled right out. The spring that is attached is almost identical to those found in version 2/3 gearboxes and functions in the same way.

Next part is the selector piece. This part interacts with the selector on the gun and will make your gun go full-auto or semi-auto depending on it's position. if you flip the gearbox over you can actually see how it directly interacts with the cut-off leaver.

It should be left alone but just encase it does need replacement there is a screw on the out side allowing it to be removed.

Lastly there is the trigger switch. This piece is pressed into place and once the spring is detached from the gearbox post, the switch can be pulled out as shown.
