Important Information

The Umarex Zelos already features a factory regulator that controls the rifle's operating pressure. This bottle adapter is factory preset and is not intended to be adjusted for tuning the rifle. If you wish to adjust your rifle's shooting pressure, use the factory Umarex Zelos regulator.

Do not adjust the bottom adjustment screw unless you fully understand the regulator's operation. The output pressure should never exceed 250 BAR (3625 PSI).
