Hi,

Just have a few questions about the V6 gearbox (Specifically the ARES TAR-21)

I was wondering what kind of air nozzle, piston head and piston is compatible with it. Would the V2 parts work?

Also is there an aftermarket MARS sight or some rail I can add to the gun to replace the stock ARES MARS sight?

Thanks in advance.
