Utilizing the performance and design of Nine ball's famous "High bullet valve" series of gas blowback valves, the next generation of Laylax valves are designed with green gas in mind. Optimized for green gas using the VFC gas systems inside of their Glocks, you can expect increased velocity, higher stability, and more consistent shots. 
As is standard in the other high bullet valve designs by Laylax, these valves are adjustable, with the valve fully opened you can expect a higher velocity from your Glock, while closing the valve reduces pressure output which lowers the velocity, perfect for summer and hotter environments where your Gas pistol may shoot higher than typical.

 Made in Japan

Valve Maintenance:
Apply silicone oil to the valve from the outside of the magazine, without removing the valve every 10-20 magazines worth of shots or for long term storage.
