HPA Mechanical Engine - Mancraft PdiK V3 (with gearbox)

Selling this Mancraft Mechanical engine, which works even underwater!
I've used it on my AK but it's time to say goodbye, as HPA refills are hard to get in my area.

The engine still works well, although the gearbox has a few holes for alignment and for the hose.

Mancraft does provide a life warranty on their parts, so any issue you might encounter, you are still covered.

Any questions DM. I can send this via Vinted for cheaper tracked shipping.
