||This gun is a high power, high performance AEg by JG. Most of the gun is metal, except for body and a few other parts. The handguard and retractable stock are nylon. Out of the box, the JG M4 shoots about 420 FPS with .20g BB's. The range is about 150+ feet. Overall, this gun is more for outdoors wars, not CQB. The ROF is pretty low, and the High Cap magazine holds only about 30 rounds per spin. The magazine holds around 320 rounds in total, however. This gun is the same thing as the S-system M4, and this is the 2012 model. The Front and Rear Sights are flip up. I don't like the front sight because it has a very small reticle. The battery compartment (in the handguard) is a very tight fit and only fits 8.4V batteries.
Great range and velocity
Mainly metal and nylon
Heavy (good or bad)
Flip up sights
Rails on both sides, bottom and top
Plastic body (But the gearbox and internals are metal)
Overall, I highly recommend buying this gun for $145.
