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.
1.9 Joule Spring, 375mm Inner Barrel, 0.2g 6mm BBs.
- Position 1: 450 FPS (full power)

This will work in:
- Standard Version 2 Gearbox.
- Standard Version 3 Gearbox.
This will not work in:
- Next-Gen Marui Gearboxes (i.e. shock recoil).
- Tokyo Marui PSG-1.
- Extended Cylinders.
As the piston has steel teeth make sure you have good gears. Over time, steel piston teeth can grind down cheap, low quality gearbox gears. When purchasing this piston, consider stepping up to better gears if you have not done so already (a good choice is Systema gears). The metal piston head also creates a wear issue; ensure you have a decent gearbox as repeated impact from a metal piston head can damage and crack low quality ones.
