An NPAS allows you to tune your GBBR to your desired FPS/Joule output easily and seamlessly on the field using a simple 1.5mm hex key (found in most hex key toolsets). Once installed (which is demonstrated here on our own very clear video), simply remove your bolt 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 under limits no matter the time of year, BB weight, or with gas/pressure used. It really is a “must-have” component.

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

– Tokyo Marui

– Unicorn

– Dynamic Precision

– Double Eagle

– Salvo Precision

– Gunsmodify

– T8

– Prowin

The material used is a stronger Nylon Polymer in the iconic Crimson red, making it extremely easy to identify on your tech bench as well as when it is installed. You will no lose track of who’s MWS NPAS is who’s (not that you will need any others after this).

Crimson, it’s red

*Installing an NPAS will require some teching knowledge and a small amount of tools. A video here demonstrates the installing process. Be careful when adjusting your NPAS to ensure you don’t totally unscrew the adjustment screw, this goes for any NPAS on the market. If you have any questions please contact us*
