Remove the ***** that sticks out the front of the piston head, it's called an airbrake and will greatly reduce your fps if over a certain amount (get ready for a loud SPROING though). Either cut it off or unscrew it. A VERY common problem you have, applies only to the VSR when upgraded. A teammate upgraded his VSR a bit over 400fps, and he'd only get 330fps max out of it with 0.20g until he castrated the piston.
