I have it. Its decent quality. Forget what it chronoed at but its a decent gun. For the price it cant be beat, and the money you save can go towards upgrades. The externals are all plastic like any other combat machine but the plastic is pretty durable and a good flat color (not this shiny black crap)
My one complaint is the stock. No matter what I have done it will not stay screwed in. It will just unscrew itself slowly over time. It gets really annoying, and short fo gluing the screw in I dont know what to do. I also lost the screw that holds the motor up in the pistol grip, normally this will render the gun inoperable from what I have read, but my gun still seems to work fine. Also when I got the motor connections were loose and I had to fix it.
Other than that it is a good gun. Its also 20 dollars cheaper now then when i got it :p
