Replacement main piston spring for many Crosman air rifles, including the following models: Quest 1000, Storm XT, TAC 1 Extreme, Phantom 1000, Optimus, and TR77. US specification. Genuine Crosman factory replacement part, specially packaged by Archer Airguns.
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 Crosman warranty on your air rifle.
