CQB Valve

Take Your Fight Indoors

CQB Valve 3

Drop your FPS with the CQB Valve

Developed on the idea of early valve timing, the CQB Valve is designed to lower the FPS of your KWA NS2 pistol or SMG to a CQB field limit.

The need for this project came after purchasing my KWA Mp9. The Mp9 was shooting just too hot for my local cqb field. I needed to get below the limit of 350Fps w/ 0.20′s. I did not want to fiddle with the hammer spring and did not want to sacrifice accuracy with a shorter barrel. With the CQB Valve, I was able to reliably reduced the FPS output of the little SMG.
