This gun is great. I actually got it last year, but I'm just now finding time to get a review up. Solid ROF with a 9.6, shooting just under 400 with .2s. The gun is incredibly sturdy, after a year I hear none of the creaky plastic-y sound in the lower receiver that I hear on my other guns. Having the forward assist spring release is awesome. The only thing though, is you shouldn't release the spring unless you're done shooting. It does not reset the position of the gears so you might find yourself firing full auto when set to semi until the gears reset. Not a big deal because I only do it when I'm done shooting. The cranestock is pretty easy to get your battery into, but the buffer for smaller batteries can be a tad frustrating sometimes. The only main problem I have is that the wiring has to be pretty much stuffed into the stock because the wire in the stock has a stiff sleeve around it so it's not very flexible. As a result the sleeves on my battery connector have become a bit loose.
All around an awesome gun, I highly recommend it.
Solid ROF and power
Convertible outer barrel
forward assist spring tension release
monolithic top rail
polymer u/l receiver for no creaky noise after time
wiring in the stock could be a little better to allow more room for the connectors
