"I bought this for my CYMA VSR-10 and oh my goodness i was getting 600 FPS with only an aftermarket 6.01 inner barrel and this upgrade kit. Not only did it preform good it preformed too well so im gonna buy a different spring to follow my field limits

"I drop this in my vsr 10 gspec and it shoots 549fps.

It is the only mod I did.

"This does not fit the stock cylinder of the Well MB03. The inside wall of the stock cylinder is too small for the piston. Piston must be modified to fit. Its best to get a complete cylinder and piston at the same time.
