The Huben airgun in basic version is provided only with a pressure gauge which shows the regulated pressure, which is a disadvantage, as the shooter can not control how much the pressure in the airtube remains, and thus the number of shots before recharging. We have decided to remove this disadvantage and offer the Huben Rifle owners a quickfill that already has a built-in manometer and so it is possible to continuously monitor the pressure in the airtube or fill the airtube to the required pressure according to the manometer. Quickfill has pressure gauge up to 300 bar, but the maximum pressure for the manometer is only 280 bar.
