Pack of two replacement main piston seals for Chinese B3 air rifles. These parts were manufactured by Shanghai Airguns and fit current and recent production examples of this airgun.
Requires an airgun spring compressor and specific knowledge to install. Do NOT buy unless you have the appropriate equipment and understanding to do this.
DO NOT DISASSEMBLE your air rifle for any reason unless you know what to do and how to do it safely. You may risk serious injury or even death! If you have any doubts, you should contact a professional airgunsmith. Dis-assembling the air rifle will invalidate the warranty on your air rifle.
