First off, I'm writing this review to hopefully clear some things up about this gun. When I first opened it, It was an absolute beauty; the pictures on here underestimate it's looks. Full trademarks and all! If anything, the thing that I don't like is this warning sticker on the left side of the gun. Don't worry though, There's actually a warranty seal on the inside of the magazine well, so I don't think that the warranty would be void if you take off the sticker... although I wouldn't just to be safe. The upper receiver is made out of high quality aluminum (possibly CNC) and the lower is made out of very well made plastic that I find excellent.
Another thing that I would like to clear up is the battery space: I read the reviews on this gun and I thought they were just complaining about how they couldn't fit a 10v battery in it, but when i opened up the space, I found it to be REALLY small. I couldn't fit my 9.6v mini in there, and I don't think others would work besides an 8.4. What I would strongly recommend is a 7.2v LiPo battery to get so you can still have the power of a 9.6v while in a small size.
Overall, this gun is fantastic: the performance, externals and all. I don't recommend this to beginners however because the idea of getting a LiPo since it doesn't come with a battery.
Externals are amazing
Performance is excellent
Most realistic replica on the market
Fully ambidextrous controls
functioning bolt catch that has 'dat crisp sound
Comes with a metal black flash hider
IT'S A VFC
Wiring could be better
