I won this gun during a raffle at Operation Crazy Horse. I\'ve done minimal upgrades to the gun to bring up the FPS and range (I primarily play field games). I also re-shimmed and re-greased the gears when I replaced the stock motor. I\'m actually shocked at how good the range is on this gun considering I haven\'t upgraded the hop up bucking. It is still stock. I\'ll replace it when the range starts to drop off. I also bought a replacement \"complete upper gearbox\" (320 fps) for use in CQB arenas (if and when I ever go to one). It\'s a cool little gun that really comes into its own in close engagements.
