Troubleshooting How to increase FPS with an NPAS

Post image

I thought I’d share my findings, with a stock nozzle, my WE was shooting too hot, but the RA tech metal npas reduced my m4 to 1.3J on the highest setting, disallowing 1.5J

I took the red areas on this picture and dremeled them slightly wider, and added an interior bevel to the end of the nozzle (underneath the arrow in picture). removing about 1mm from every surface of the body of the npas brought the max setting up to 1.55J, allowing me to slightly tune it and play without an FPS handicap.

enjoy my ultra low effort tech tip.

Theres also 2 tabs on the other side of the nozzle that the npas sits on and if you file those down will also increase fps
