This gun is very decent. Full metal with Magpul, and Magpul is always very good. The FPS is high enough for every filled game. I really love the Electric recoil of this gun. Also the sight is clear and accurate. Adjustable hop-up is very easy to use. This gun is amazing, because you can shot it with a high-cap mag without pause. And the mag is plastic, so you can drop it in ground when you reloading. It is reliable.
Enough FPS for field game
Amazing shot experience
unstable stock(just a little bit)
mag is not very stable also
my RM4 was stop working once because the button in the inside body(in the mag connection area ) was jam. Really easy to fix it with an toothpick :D
