- Upgrade kit - 575 FPS approx
- Alu piston, ball bearing spring guide & main spring included
- Compatible with CYMA CM.703 and CM.707 Sniper rifles
If you want to squeeze a bit more range from your CM.703 or CM.707 sniper rifle this upgrade kit will do it! The CYMA Upgrade Kit For CM.703/707 Sniper Rifle includes an aluminium piston, aluminium ball bearing spring guide and M175 main spring which should provide approximately 575 FPS with a 0.2g BB when installed in a rifle with good air seal.
As always, we recommend checking the FPS/joule limits of your local site before installing the spring, but the piston and spring guide can be used with the standard spring in your rifle to provide improved strength and long-term durability if your site limits your rifle to 500 FPS.

Parts Fitting
Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Unique Parts
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
For more information with fitting parts, or should you require help, feel free to get in touch with our Workshop Department via our Contact Us Page.
