So here is the gun:
* Looks good
* all metal (except for LOWER receiver and pistol grip)
* very heavy
* comes with battery, charger, a pair of shooting glasses, forward grip and rail covers
* excellent accuracy with minimal hopup adjustment
* functions pretty good as a indoor and outdoor AEG
* charging handle and forward assist work, but dont do anything
* battery goes into the stock and stock cannot retract all the way, if i do push it, it cuts the battery wires. Getting the batteries in there was hell to begin with.
* advertised fps was 350-360 actual is 300-310 fps
All in all I would say I am satsified with this as a great first gun. I am 5'10" and it fits my body size perfectly.
Some other dude made a youtube review of this gun. Its about 4:00m in. He's off on the specs of the gun, but at least you get to see it in action.
