[Army Force]CNC Aluminum Complete Gearbox[For A&K /CA M249 AEG Series]

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.
