||I got this gun a few weeks ago, and I have to say, I'm impressed with it so far. It hasn't broken down, like several of my "full metal" M4 AEG's have right out of the box, which definitely puts this gun in my "win" column.
That said, the gun is a little creaky, there is a noticeable seam running down the middle, and where the optics rail is mounted wobbles, and cannot be secured, as far as I've seen (the rail itself doesn't wobble).
The gun fires pretty hard, much harder than I expected. It's range is still CQB, though, this isn't what I would use in an outdoor environment with engagement ranges of over 50-70 meters.
The only real problems I've had with this gun is that the flash hider that comes with the gun is ultra flimsy, it will break if you run into something too hard. Get a metal flash hider as soon as possible.
The battery space is also a lot smaller than you would think. I have an 8.4 mini nunchuck set up, and there is barely enough room for it an all the wires. If you have a PEQ box, I'd suggest using that (though you may need to drill a small hole in the handguard for your wiring, but it's not like this is a 500 dollar investment)
Other than that, this gun is absolutely solid. Lightweight, extremely maneuverable, can accept a good amount of accessories (get the metal rail pack if you plan on putting anything on this. http://www.zahal.org/products/tavor-picatinny-rail?path_pare-
That's a link to a handguard rail for grips or anything else, should you want it. It's expensive, but I haven't found another tavor tailored handgaurd rail out there)
-Shoots hard and accurate
-Tight magwell (little or no mag wobble, accepts Beta project P-mags and many others)
-Full metal gearbox
-Quick change spring
-good amount of rail space (with the rail pack)
-Functioning charging handle (bolt release also relaxes the spring, very handy)
-Creaky (but still solid, I'm not worried about the gun coming apart)
-Not suitable for ranged engagements
-Stock plastic exterior parts are crap
-fire selector doesn't really lock into place when on semi
