"I got this gun on December 29th, 2011 and it has done nothing but impress me (after owning a JG, I am kind of easy to impress). It is incredibly accurate (150-200ft easily, once sighted in PERFECTLY), it hasn't jammed once (I just recently cleaned for the first time, I didn't clean it for a test I was doing), and it isn't 453 FPS, it's more like 400-425 FPS, but FPS isn't everything at all. The externals are aluminum/pot metal (not possible to weld, but the metal is too thick to crack). I have put 28,000 rounds through the gun and haven't heard any crying from the motor, nor the gearbox. Lately; however, I had to swap the gearbox due to a hairline crack that formed on it, but that is prone to happen with a V2 gearbox. Smart charger should be required for ALL airsoft guns, so you should buy one.
I have also dropped this gun and got it completely soaked with water (another test to see how tough this gun is) and I saw absolutely no problem with the gun whatsoever. The hairline crack on the gearbox formed at 25,000 rounds by the stress of the spring, which is somewhat normal. Overall, amazing rifle, I would recommend this to all airsofters because it is durable, reliable, accurate, painful, and realistic as heck. Although it is heavy (10-12 lbs) you get used to the weight."
