RA-TECH - SAT Variable Velocity Device PistonRA-AE-SAT-002
This piston is part of a set for SAT Variable Velocity Device (VVD) and serves as a replacement in case you have a damaged piston for your VVD. It is made up of polymer but has metal (steel) full teeth. The use of such 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.
Gearbox fitment: Ver. 2 and Ver. 3 (Exception: Next Gen AEG, PSG1, Extended Cylinder)
Package includes: VVD piston/piston head
Fits both Ver. 2 and Ver. 3 gearboxes (Exception: Next Gen AEG, PSG1, Extended Cylinder)
Allows FPS to be adjusted from field to CQB levels and vice versa
Does not require disassembly of gun to adjust fps once installed
Recommended Notes: 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
