Huma-Air External Tuning Regulator For The CZ 200. The Huma regulator will regulate the air pressure in your S200 airgun. It reduces the primary high fill pressure in the cylinder into a lower pre-set working pressure. This will give you a constant pellet speed and a higher accuracy; no more compensation on the HFT lane!
