I bought this for my G4-A3. It was laid next to the gun box inside the brown box it came with, which i was kind of uneasy about. It gives my G4 a very nice rate of fire, but does not fit into the little battery organizer thing that comes with the crane stock, so i have to just lay it plainly into the stock. It is heavy which makes it fun to play around with but i feel like I'm going to break the wires off if i do it too much. It also dies pretty fast. I charge it with a standard wall charger for 6 hours until its hot and i got 1000 rounds off with it in a week time span.
Good rate of fire
The color it comes in is kind of neat. XD
Charge doesn't hold too well
Wires are a little brittle
