I have owned a JG G36c (a very reliable gun i must say), the KWA M4, and this gun. This gun is by far superior in accuracy, RoF, and in looks/feel than any gun I have owned. First off, it is the most solid gun I have ever held, i don't feel like anything on it will ever break on me during a game. I don't have a chrono, nor have chrononed it, but there is a semi formal type of chrono, called "The poor man's chrono." Basically, if your gun can shoot through different parts of the can, it is approximately rated at a certain FPS. The gun I got is unofficially rated at 385fps. Comes with a tightbore 6.04mm (the Barrel, in case you want to upgrade is 540mm long), making this extremely accurate. I am running a 9.6V 3600MaH battery, and it is INSANE. It fits quite well in the stock (make sure you insert battery first, then cables). I've heard people having trouble taking off the flash hider...I have no idea what they are talking about. There is a set screw, you MUST take out (very small on the flash hider). after that it is a REVERSE thread to loosen (twist right to LOOSEN).
Front sights don't come off, rear sights are removable if you want to add a red dot, or some sort of ACOG style scope, which i would suggest for quick aiming and looks.
-Vertical grip is actually very stable when mounted, im relatively surprised
-Iron sights are nice.
-Comes with wrench, front sight adjustment, cleaning rod, RIS rail covers, and vertical grip
The high cap that it comes with, is EXTREMELY loose, however it hasn't missed a feed yet...more just of an annoyance than anything. Also the RIS rail, has a very very minimal amount of wobbling. It really isn't a con...just trying to give the most thorough review of the gun. The RIS rail covers are a bit of a hassle to get on, but you want to make sure you do it right, because they will slide off otherwise.
