Our take: The JG replacement full metal gear set works in version 2 or version 3 gearboxes. In comparison to other metal gear sets, this set features an excellent balance between quality, durability, and value.
- Reinforced stock gears to improve durability
- Ready to use right out of the box; professional installation is recommended/may be required
Note: Any and all airsoft upgrade parts purchased from Airsoft Megastore will be used/installed at owner's discretion. Actual performance results depend on quality of installation, airsoft AEG barrel length, tightness of the air nozzle seal, and other possible performance-affecting factors. We are not responsible for any damage that may occur with improper installation. For best results, please do all upgrades at a certified professional airsoft technician/shop.
