A spare knurled ring for JTS Airguns is a small metal component that is used to secure and adjust various parts of the airgun, such as the barrel, scope, or bipod. It is specifically designed to fit JTS airguns and can be used as a replacement part if the original knurled ring becomes damaged or lost. The spare knurled ring is typically made of high-quality materials to ensure its durability and ease of use. It is an essential component for shooters who need to adjust their airgun's components quickly and securely. Without a properly functioning knurled ring, the airgun's components may not be securely attached, leading to potential safety hazards and inaccurate shooting.
