Guarder Cylinder Enhancement Set for P90 / E90 Series Airsoft AEG

"OHMYGOODNESS...
This kit is amazing

Im using it in my marui and it gives a 15-20fps increase off the stock one. I am running a m110 spring and getting around 360-370fps after about 5k rounds.
Piston can handle up to a m130 with my tests (wouldnt go over that)


Amazing quality parts. Definitely recommended.
