Hi ! I have a Huben GK1 without a regulator.
I wanted to know some information about the Huma Air 70-165 bar and 100-200 bar regulators. How many seconds or hundredths of a second do they take to fill with air between each shot ? I'm considering getting one, but I'm afraid the rate of fire will become too slow with a regulator.
I know that the 100-200 bar regulator takes longer to fill with air between each shot than the 70-165 bar regulator.
