The piston is polymer but has metal (steel) full teeth and a metal piston head; the use of materials lends this piston for use in higher powered setups (over 400 FPS and high rates of fire).

This piston will install in to standard version 2 and 3 gearboxes but is not compatible with Tokyo Marui next-gen gearboxes (i.e. shock recoil) nor will it fit into PSG-1 gearboxes or extended cylinders.

The adjustment tool is made up of a hollow metal handle and a set of metal rods. The rods can screw together end-to-end to a total combination length of 700mm. Of course you only have to use as much length as you need. Each segment has a small hole running through it which can be used with a small Allen key to get much better torque grip on it to tighten and loosen the components. The valve on the VVD piston is rather tight so the tool has to be screwed together tightly to may adjustment easier. Similarly, the tool will likely need a pair of small Allen tools to loosen if the rods are screwed together more than finger tight.

Although a new product, some testing has been performed prior to release. The VVD was tested in a version 2 gearbox inside an M4A1 with two different springs. In each case, the guns where tested for the FPS values at the 3 positions of the VVD; the results are as follows:

1.9 Joule Spring, 375mm Inner Barrel, 0.2g 6mm BBs.
- Position 1: 450 FPS (full power)
- Position 2: 340 FPS (20% drop )
- Position 3: 270 FPS (40% drop)

1.3 Joule Spring, 375mm Inner Barrel, 0.2g 6mm BBs.
- Position 1: 380 FPS (full power)
- Position 2: 315 FPS (17% drop)
- Position 3: 240 FPS (41% drop)


In pratica si va con una chiave lunga dalla canna e si regola l'apertura dei forellini dell'antivuoto da quello che ho capito, questo permette di regolare la velocità del pallino in uscita.
