KWA's MP9 Low Power Bolt is a complete drop in bolt assembly that will lower the velocity of your KWA KMP9 to CQB levels. Whether you want to use your MP9 in CQC, or you just want the quick-change FPS option, the KWA MP9 Low Power Bolt is the easiest way to lower the velocity in your MP9.
This part is designed for experienced users only. Disassembly of your GBB MP9 will void the warranty. Installation should be performed by an experienced technician. For tips, check out our KWA MP9 Low Power Bolt Installation Guide.
Since the KWA KMP9 Low Power bolt is a drop in assembly, it is a fairly quick swap to change from high velocity to low velocity. No modification to parts is required, so converting back is as simple as swapping parts again.
On our test model, installing this bolt lowered the velocity from 395-415 FPS to 320-330FPS.
