      Works well, very happy

      Arrived nice and quickly, fits well in the gun, wiring is high quality and the machined aluminium casing is quite impressive for airsoft parts.

      Out the box this is a decently powerful setup - I am getting 400fps and a rate of fire of about 600 rounds per minute. Also has an upgraded microswitch for the trigger.

      I'd recommend this to anyone looking for a replacement or upgrade over the stock gearbox. I actually need to tune mine down a bit, since it's too hot for my local site, which is easy enough thanks to the quick change spring.
