Eagle 6 Airsoft - TM AEP/CMG M80 Spring

Manufacturer notes: This spring is specifically designed for ALL AEP & CMG series from Tokyo Marui. It's probably the most powerful AEP spring available, and we actually made this spring slightly stronger in testing and found it to be too much for the gearbox to turn. So, we came back and settled on this design as the strongest spring we could make. This spring is as strong as you can go without sacrificing all of your ROF and battery life. As evidenced by the video below we have seen fps readings as high as 305 fps on some TM AEP's, the USP having the best chance of a higher fps due to its joined hop unit with Gearbox. These springs are Heat treated 3 times and use high quality steel and are Made in England. These Springs are tested every 10 springs and measured for consistency during a batch manufacturing process. These are also deliberately made as a linear spring for a more consistent fps reading shot to shot. Please note: when fitting into CYMA guns, the original spring will appear vastly shorter than our spring. Don't worry; CYMA just makes really small and weak springs. - Increases AEP FPS as high as 300 on some models. - A slight decrease in ROF is to be expected; we recommend switching over to LIPO. - Made with high-quality steel - Heat Treated - Measured every 10 springs - Linear Spring for increased consistency
