Description
The CYMA CM.098 SR25 V2 Long Gearbox Set w/Motor is intended as a drop in replacement gearbox for SR25 AEGs which use the version 2 long gearbox. This gearbox is the same provided in the CM.098 series and has an alloy shell with radiused cylinder window to reduce stress when used at high FPS.
The gearbox includes CYMA's basic MOSFET/ETU which is pre-wired in and reinforced steel gears which run on 8mm ball bearing bushings for super smooth running. As a bonus, the set includes a high torque motor with Neodymium magnets which should give an impressive trigger response when installed.
This gearbox is compatible with the CYMA CM.098, and should also work in other SR25 AEGs which use the V2 Long gearbox type (A&K, Classic Army). This gearbox is not suitable for a normal M4, or the G&G or Ares pattern of SR25 as they use standard version 2 gearboxes.

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.
