"Crimson" NPAS for MWS TM / DE / Salvo Waldo Dynamics® (WD-MWS-NPAS)
BRAND WALDO DYNAMICS®
The "Crimson" NPAS by WALDO DYNAMICS®, developed in collaboration with Bristol Based Airsoft, is an NPAS system designed to provide precise power adjustment for compatible MWS GBBR platforms.
This upgrade was developed to ensure compatibility with a wide range of stock and aftermarket MWS nozzles, allowing easy and effective FPS and Joule adjustment.
The project was developed and tested across numerous nozzle designs to provide maximum compatibility.
What is an NPAS?
An NPAS allows users to easily adjust FPS/Joule output directly on the field using a simple 1.5 mm hex key.
After installation simply:
- remove the bolt
- access the nozzle from the front
- adjust the internal screw
- Clockwise: lower power output
- Counter-clockwise: higher power output
This allows quick adaptation to field limits depending on:
- temperature
- gas type
- BB weight
- field regulations
The Crimson NPAS is manufactured from high-strength Nylon Polymer in the iconic Crimson Red colour for easy identification during maintenance and tech work.
