Optimise your airgun’s firing cycle with our precision-engineered Weihrauch Beeman 30mm Short Stroke Piston Seal. Designed explicitly for 30mm cylinder actions—including the Weihrauch HW80, HW35, and Beeman R1—this upgrade incorporates a 12mm short-stroke extension built right into the seal design. By shortening the piston's travel distance, it dramatically reduces lock time, minimises hold sensitivity, and improves accuracy. This is a completely self-contained unit with no extra set screws or loose pieces, ensuring a secure and simple drop-in installation.
