Mounting kit for air Hill pumps, which additionally extends them with a filter that dries the air during filling, thereby extending service intervals. The filter protects the cartridge, barrel and other internal mechanisms from atmospheric moisture and thus prevents corrosion and damage to the weapon. Attention, the filter is only intended for Hill MK4 and Hill MK5 pumps.
Attention, the filter is not intended for the MK1, MK2 and MK3 pumps and for the Spartan MK1 and MK2 models, but only for the Hill MK4 and MK5 models.
