The CYMA M14 is pretty cool, but upgrading it has been a headache. Our initial upgrades (tight bore barrel and mosfet) proved very effective in increasing the gun's performance. However, a new piston head and air nozzle actually regressed the gun in performance. Unfortunately we have not returned to upgrading the gun since and so this review is a little incomplete. Someone asked me to make this several months ago, so here you are.
