Huma-Air Hatsan AT44 Tuning Regulator .25 /.30XXL

For the Hatsan, AT44, Bull boss and Trophy air rifle, we have a pressure regulator available that can be pushed into the pressure tube.

This regulator is vented to the atmosphere without any modification to your pressure tube. So no drilling in the tube and also no creeping up in power during time.
