I've had a VERY mixed experience with this gun. I've owned it for two years, and I must say, gameplay wise it is amazing. The overall feeling and weight is amazing. It's made out of solid poly-carbonate material which I would prefer over metal in any situation. It fires accurately, fast, and hits decently hard. Not to mention how easy it is to shoulder and move with.
The not so good part- Maintenance. This gun is absolutely horrific to work on. If you ever plan on taking it apart yourself for any reason, don't. It takes an hour alone just to remove and open up the gearbox. The gearbox shell is unique with several unique parts inside and out. The trigger mechanism uses a lever and pull rod instead of the standard electrical mechanism, which fails very easily. There are many other problems, but to be short, DON'T TAKE IT APART!!! I first opened it a year ago and it has not worked correctly since!
-Absolutely amazing feel, weight, and handling
-Very good Rate of Fire
-Hits hard, but not too hard
-Sturdy and stands up to punishment
-Accepts M4 magazines, which are common and inexpensive
-Unique gearbox parts and shell
-Low quality motor and piston
-A rail riser is needed to be able to see through any after market sights correctly
-Very difficult to remove orange tip (I broke the bracket holding the barrel inside the gun doing this)
-Very small battery compartment
-Semi Auto works about 50% of the time, usually requiring you to swap from Full Auto and back to Semi
