I bought the gun roughly 3 month's ago and knew it was a bad idea to do a review instantly cause of the excitement over the first few days. Plus I needed to actually use it a few times in some battles to get a feel for it. Its a pretty good gun I'd say a high 3 low 4 out of 5 stars I have a few minor problems with the gun's construction. Keep in mind my rating might be lower than it deserves cause this is my first professional grade AEG, I had a JG M16 advanced version before.
The gun is very well built minus a few wobbly spots here and there but for the most part well done. Its full metal minus the stock which houses the battery, the hand grip, the rail coverings, and the forward grip. The few wobbles include the mag and the stock at first, if toyed with to much the forward rail covering assembly with start to have a little wobble but like I said thats with toying around with it so its not a problem. The mag well is pretty big compared to the mag so the wobble there is excessive, some duck tape on the top of the mag solves it for the most part. The stock does have some wobble but its not excessive and doesn't subtract much if anything from the guns rating. Other comments on the exterior of the gun, the selector switch has a beautiful click and you know when it has changed, the body work over than the few wobbles mentioned is exceptional unlike my JG M16 which has some body issues. A very personal issue with it is the rear sling mount behind the hand grip, it is a small slit so it cuts down on what slings work for the gun. The dust cover which covers the hop up can be slightly annoying to pull down to adjust the hop up, I wish that the cocking handle on the gun was set up to reveal the hop up unit like the JG M16 does. That about sums up the exterior. One other small thing is that the flash hider on this gun does not seem to be that much fun for customization and compatibility with silencers, I got a halo gemtech silencer which goes over the flash hider and it didn't fit so I switched the flash hider on my M4 for the one on my JG M16 and it worked well.
Interior and disassembly: I am not genius when it comes to either of these but I can give my point of view on each. For me the disassembly was basically impossible I wasn't able to achieve it with some quality effort on my part, I know about the few tricks that some dont know about G&G disassembly but I still could get it apart, then again I didn't really need to. Interior as far as I know is very good, I heard the gearbox is one of the best on the market for durability but if you want to put a new spring in the gun lots of extra upgrades could become necessary like new gears, maybe a new motor to get back the ROF lost but thats true of any gun unless it has the best motor on the market already. The hop up I am not sure I am impressed with but then again it might be good and the what seems to be a lack of accuracy is the lower FPS at 340ish. Personally I am looking to get a new hop up and a new spring for better accuracy, range, and power. As a CQB weapon it has good fps toping out around the cut off for CQB fields. That might have been my problem is I am a field player but I like M4's so I am looking for more range and accuracy at those ranges.
Summary: Again I believe that my ratings of this gun might be hard but its cause I spent over $300 so I was expecting it to be of possible higher quality with the accuracy and range, possible power. Even with all the minor flaws I found I think the guns is still amazing and would recommend it for a good CQB or mid-range field weapon, something I did not mention before was the amazing ROF, it puts out 4-5 extra rounds were second than alot of ECHO 1's and other MPEG's that have a good rate of fire for their quality ranges.
FPS for CQB
Accuracy to a point
Crane stock battery compartment
Lots of rails
Accuracy for long fields
Range for field games
FPS which affects range for field games
Non-flip up sights
Hop up I heard wasn't good, might be the lack of fps for field games
Rating: [4 of 5 Stars!]
