An original quickfill with a manometer is produced for the Huben air rifles directly by the producer, replacing the original cartridge cap and enabling the user to watch the pressure during filling the gun more comfortably. Huben has listened the wishes of customers and new models are now equipped with two manometers. Keeping in mind the customers who had bought Huben K1 air rifle with only one manometer, Huben produced this simple reassembling kit.
This original reassembling kit made by the producer has no limits for filling pressure, enabling the full potential of the air rifle to be employed.
