why do you want to up it 20 fps you wont see any difference in performance

maybe a better piston, but yeah why 20 more fps.

dono if the CA piston heads are different from the marui ones. but you could drill some small holes around the face of the piston head so that it will act like the systema plycarb piston head. the o ring should retract when the piston is being pulled back, and then expand for better compression when the piston releases forward.

If i wouldnt know a difference then i wont bother thanks for your help

good idea... but I might suggest making it go down to 350 so you can play CQB. If you spring is new it should break in about there.

some people like the extra 50 at the hill and nam so they buy velocity reducers

But an mp5 isnt the best "range" gun out there as far as accuracy.
