For: Guarder High Performance Valve for MARUI HI-CAPA 5.1Product Information:
This valve is my favorite of the 3 guarder valves. Its a great valve in between the high output and the high flow. If you are familiar with how the mags work, this valve, only having 1 hole, points the gas flow upward (if positioned that way) and prevents gas to expanding downward decreasing efficiency.
I saw an increase in fps, recoil and crispness in blowback.
Increase in fps was about 15-20 with a warm mag. With 150% springs, metal slide, this valve and a warm mag, i can easily get 1 and a half mags with no problems locking back the slide after the first mag.
I definitely recommend this valve.
Increase in FPS
Quicker, snappier recoil
respectable gas consumption
slight increase in gas consumption (more gas used per shot).
