Product Overview

An NPAS allows you to tune your GBBR to your desired FPS/Joule output easily and seamlessly on the field using a 1.5mm hex key. Once installed, simply remove the BCG from your GBBR, adjust through the front of the nozzle with a hex key (Clockwise for less energy output, counter-clockwise for more), reassemble and test your results.

This is perfect for players looking to be within site limits no matter the time of year, BB weight, or different gas/pressures.

The Crimson NPAS is compatible with the vast majority of MWS Nozzles, including;

Tokyo Marui
Unicorn
Dynamic Precision
Double Eagle
Salvo Precision
Gunsmodify
T8
Prowin

The material used is a strong Nylon Polymer in the iconic Crimson red, making it extremely easy to identify on your tech bench as well as when it is installed.

NOTE: Installing an NPAS will require some technical knowledge and appropriate tools. Be careful when adjusting your NPAS to ensure you don't totally unscrew the adjustment screw, this goes for any NPAS on the market.
