Description
The Air Arms S400/S500/HFT 500 Huma Regulator is a precision-engineered upgrade designed to enhance the performance of Air Arms S400 and S500 series air rifles. This aftermarket component significantly improves shooting consistency by maintaining a constant output pressure, regardless of the cylinder’s pressure. By regulating the air flow, it eliminates velocity fluctuations, resulting in a flatter shot string and increased accuracy across a wider range of shots.
Installation of the Huma Regulator can be performed by experienced users or gunsmiths, following detailed instructions provided by the manufacturer. ?The regulator is available in different pressure ranges to accommodate both standard 12 ft-lbs models (60-110 bar) and FAC rifles (100-170 bar) in various calibres. Users report improved shot count, reduced noise, and better overall performance after installing the Huma Regulator in their Air Arms rifles
