First off, AirsoftGI service was great and detailed. Thanks you guys!
This gun is a beasty CQB weapon. AirsoftGI tested velocity was 335 FPS, and I would say it shoots around 19 to 20 rounds per second with G&P 9.6V 3300mAh PEQ style battery. Although the gun is plastic construction, it is extremely sturdy. Looks like it is going to need heck of beating to actually break this gun. There are slight wobbles on places though. Orange tips are easy to take off. Just blow dry it for a few minutes and stick a screw driver through the bird cage and simply unscrew it. It may require some strength, but it's really not that big of a deal. Range is pretty decent; about what it AirsoftGI says - 120feet - and groupings are quite tight. I got 5 inches grouping at 60 feet, standing up shot. No fancy aiming skills were used. I simply stood on the porch and shot with no concentration of whatsoever. With this accuracy, you can sure hit a human sized target at a hundred feet.
As far as the maintenance goes, it is pretty simple. I'm not going to bore you with how to clean the barrel. You ought to know how. To lube the internal, just pop out both body pins and push forward the upper receiver about half an inch, then very gently lift it up from the lower receiver as if you were disassembling a real M4. Be very cautious because there are wires that run from the R.I.S handguard to the motor. If you are not careful, you may actually end up ripping the wires. After you lift up the upper receiver from the lower receiver, you should be able to see a little hole on the left side of the gearbox. Take your silicon oil and spray right amount into the hole and fire the gun a few times on semi automatic. Be careful though, the silicon oil may spray back out of hole on your face while you're firing :P
That's about it. Five stars.
This gun will not disappoint you.
P.S. This gun uses a PEQ style battery; therefore, the wires are exposed. I strongly suggest wrapping around the exposed wires with electrical tape to prevent ripping and tearing.

Crispy fire seletor
No barrel wobble
Wobbly LE stock
Slight robble on the rails - although barely noticable
PEQ box - making the gun front heavy
R.I.S can be difficult to work with
