Just got this yesterday and i LOVE it! I was quite surprised that this would be such a quality gun compared to previous JG versions. For my gun, there was absolutely NO RIS wobble and the body connections to the RIS and stock are very very sturday. The gun feels solid and looks great. My only complaint is that the included mag fits a little snug. Performance wise, the gun is pretty good for a clone and i was surprised. The gearbox sounded, to my surprise, very smooth. The GB was properly lubed and shimmed (previous versions had horrible shimming, my friend bought an old ver. M16 last year and the gun had no shims whatsoever) and performed flawlessly in my test firing. For the spring it is pulling (mine shoots 410 FPS) the ROF is quite good at about 16 or 17 a second with the included 8.4v, which is a shock considering my Echo 1 AK 47 (rebranded JG) that i bought last year shoots ~370 with 15/sec. JG has definitely stepped up their quality and this is the perfect proof of that.
Mag feeds well
Battery hard to get in at first, to get it in just pull out the fuse box, push in the battery all the way then tilt it to the bottom of the stock and push in a bit more, then put the fuse box and connectors in the new space.
Horrible rail covers, made of cheap plastic and are useless+hard to get off.
