CLPD Adjustable Floating Valve for VFC

Adjustable Floating Valve for VFC, suitable for: BCM, HK416, 417, SR16, M4, MK17, MK18, M110, SR25 ECC, MP7

All standard out-of-the-box VFC GBB come with a non-adjustable floating valve, but maybe some game sites are only allowed with certain FPS. Now one gun can be used anywhere, with no need to change guns all the time.
