The 1/2″ UNF Adapter – 11.5mm is a precision-machined adaptor designed for air rifles with an 11.5mm outside barrel diameter. It provides a simple and effective way to add a standard 1/2″ UNF thread, enabling the use of a wide range of moderators and muzzle-mounted accessories.
The adaptor typically attaches via a clamping system or grub screws, ensuring a secure and stable fit to the barrel. Once installed, it presents a concentric 1/2″ UNF male thread, allowing accessories to be fitted while maintaining proper alignment with the bore for safe and accurate shooting.
Constructed from durable metal such as aluminium or steel, the adaptor is built to handle repeated installation and use while maintaining structural integrity. Correct fitting is important to ensure alignment and prevent any risk of pellet clipping when using attached moderators.
Ideal for slimmer barrel profiles, this adaptor is commonly used to upgrade air rifles that do not feature factory threading, expanding compatibility with aftermarket sound moderators.
