Huma-Air Tuning Regulator For The Hatsan Hercules Bully


This External PCP Regulator build by Huma-Air is specialy designed for the Hatsan Hercules Bully with a pressure bottle at front of the rifle with M18x1,5 threads.

The regulator will reduce the outgoing pressure of your rifle's pressure bottle according to your settings and this will result in a constant pelletspeed and better groups.
It is equipped with a pressure gauge what will indicate the fill pressure of the bottle and a foster male connection to fill the rifle. The position of the gauge and and foster can be chosen left or right and they can be aligned stepless into their position so it always looks good on your rifle.

When the regulator is fitted to the rifle you can read the regulator output pressure on your rifles's pressure gauge and the fill pressure will be shown on the regulator gauge.
Pressure can be set by turning the set-screw of the regulator what can be found inside the male treaded part of the regulator. A 5 minutes turn contra clockwise equals to about 7-8 bar pressure increase.
This bottle regulator will be screwed in between the pressure bottle and the action of the rifle. It will ad about 58 mm of lenght. Please note, the male treaded part of you action, what will screw into the regulator can have a maximum length of 28 mm. If the treaded part of your rifle is longer you can check if it is possible to shorten it a bit. Feel free to contact us about it.

(your original rifle's fill connection is replaced by the regulators quick connect foster male fill connection. Do not use the original rifle bottle fill connection anymore)

Important safety notes:


These regulators are not suitable for stand alone pressure bottles/buddy bottles.
The maximum working pressure of this model is 250 Bar.
Do not exceed the factory adviced fill pressure of your rifle.
Do not exchange the original factory bottle for a higher pressure bottle version.

 

 

Please note, your rifles output power depends of the available air volume behind the regulator. You need about 12 cc for .22 and 16 cc in .25 for high power rifles. If you are not sure, measure the air channels in the action and we can help you calculate it. We will ad rifles to the list below when we have received information.

  • Hatsan Barriage and Hercules are low in volume so this is not optimal for high power applications.
