For: Systema Complete M120 Gearbox for M16 seriesProduct Information:
First impressions on this gearbox, are good, looks good, feels good etc. But there are a couple of junk parts on it, which are not hard to fix. The tappet plate is made of cheap soft plastic, the connections to the motor just snap off, and the wire to the stock, is too short. But the shell, and the internals are amazing. The pressure this gun has is outstanding, which gives it a great fps. The rof with this is very fast, i am using a Systema Magnum Motor, and a 9.6v 3600mah battery, and im getting about 27 bb's per second. Very good.
Great trigger response
Junk tappet plate
Wire in back is too short
Lacks grease, so grease it up good before firing
