I'm looking at a G&G M4 MAX to replace my slightly upgraded G&G M4. The MAX series of guns shoot 460fps out of the box, which is too hot for where I play. I do know that the G&G GR16 shoots 360fps out of the box, but settles down to 330fps after some use.
Does anyone know if a G&G M4 MAX would settle down from 460fps to a more usable 430fps? I know there is a spring included that will reduce the velocity from 460 to 360fps, but the whole reason I am considering an M4 MAX is because I don't want to open the gearbox.
