"KWA’s KMP9 is one of the most capable gas blowback guns on the market, and by far the most popular gas submachine gun. The way KWA has engineered the MP9, it is capable of outranging many full size gas blowback rifles from other companies. In order to achieve maximum range and best performance in all temperatures, the KWA KMP9 usually shoots between 380FPS and 400FPS. However, while this performance level is desirable outdoors, those that want to take advantage of the MP9’s size in CQB need a different setup.

Many CQB arenas limit the velocity to 350FPS or lower. In order to meet this limit, KWA released the KMP9 Low Power Bolt. The MP9 Low Power Bolt is designed as a complete drop in assembly that will replace the original bolt and get your MP9 shooting at an acceptable close quarters velocity. Since the bolt is a complete assembly, it’s a fairly straightforward replacement; much easier than attempting to modify internal parts would be.

This walk-through is a complete KWA KMP9 Low Power Bolt Installation Guide. Keep in mind that disassembling or modifying your KMP9 will void the warranty, and is only recommended for experienced players. This guide is not a guarantee that you will be successful, so take care and don’t force anything."
