A spare regulator head for JTS Airguns is a small metal component that is used to control the air pressure in the airgun. It is specifically designed to fit JTS airguns and can be used as a replacement part if the original regulator head becomes damaged or lost. The spare regulator head is typically made of high-quality materials to ensure its durability and accuracy, and it is an essential component for achieving consistent and precise shooting. Without a properly functioning regulator head, the airgun's pressure may fluctuate, leading to inconsistent and inaccurate shooting.
