I am wanting to start airsoft and I have chose G&G Combat Machine CM16 MOD0 carbine – tan for my main rifle. I am looking for a pistol that can be used at first and only sites, which is a max of 350 FPS and then it says actual and i don't understand it so ill just put the link here. I am looking for a green gas blowback pistol, but the problem is, is that I don't really know if it's needed. I am going to be using 0.2g bb's.
