Balystik HPR800C HPA regulator.
This has been lying unused for a long time and is currently suffering from an internal leak.
It might be possible to remedy this with some maintenance (e.g., lubrication) or a repair kit, but this has not been tested and it is therefore sold in its current state.
Supplied including the special tool to adjust the output pressure.
Shipping is possible.
Selling as pictured and in current condition.
