Huma-Air Adjustable Tuning Regulator For The RTI Priest and Prophet 1

 
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 into any position so it always looks good on your rifle.

In the packet there comes a second pressure gauge what replaces the second fill connection inside the buttstock of the rifle. When you have fitted this second gauge you wil be able to read and check the regulator output pressure.
The bottle fill pressure will be shown on the regulator collar gauge.
The regulator is equipped with a 3000 PSI safety burst disk, identical as the factory regulator
