This is a JG M4 S System. Has been fielded previously. Good field gun, runs in the high 300s to 400 FPS on a standard 9.6 volt battery using .25 BBS. The gun includes two high cap magazines, One is included free because it sometimes has difficulty feeding and the other works fine. A PEQ box is included. It is a hollow box you can use to store your battery. The compartment originally made is very tight, so the PEQ makes battery use much easier. A vertical foregrip, a flashhider, I do not guarantee the hider will be easy to install. The orange tip is on this gun pretty solidly. Finally a tan Liontac sight. As you can see it sits a little high up, but I have used it fine before without attempting to fix it. It has red and green dot sight at 5 levels of brightness with four reticle types.
