You get what you pay for. I, honestly dont really see a difference between these gun. the 2 G&G and the CA are the pro line. I personaly stay clear of that unless i will almost completely change the internals (i dont trust anything unless it is full metall internals). and the JG is shooting a little high on the fps. Unless it has metal gears and piston...the piston will be chewed up in no time. Your call dude. I gave my 2 cents.
