BSA / GAMO Piston Seal / Washer. Parachute style washer that was adopted by BSA / GAMO as a common piston seal component that was interchangeable between models. Also suitable for the Stoeger X20. If your rifle is low in power, it could be because air is escaping past the piston seal from the compression chamber. These are direct manufacturer replacements for the factory-fitted piston seal.
