Donny FL Double Sided 1/2 X 20 Male Adapter A21

This Donny FL A21 adapter provides a robust 1/2 x 20 double male connection, precision-engineered via CNC machining for exact tolerances. The component is finished with a durable matte black anodise to ensure it matches high-end air rifle aesthetics while resisting wear. Designed specifically for the Air Arms S510 and Hatsan Jet 1 and 2 models, it allows for seamless attachment of compatible silencers or barrel accessories. One side features a knurled cap to provide a secure grip during installation or removal. A dedicated through-hole is integrated into the threads, allowing for the use of a tool to ensure easy tightening or loosening without damaging the finish. With a 20 mm outer diameter, the adapter maintains a sleek profile that aligns with the barrel's geometry. This accessory is essential for shooters looking to adapt their muzzle threads for standard 1/2 UNF equipment.
