"Crimson" NPAS for VFC / APFG / Maruyama GBBR Waldo Dynamics® (WD-VFC-NPAS)

BRAND WALDO DYNAMICS®

The "Crimson" NPAS by WALDO DYNAMICS®, developed in collaboration with Bristol Based Airsoft, is a high-performance NPAS system designed to provide precise power adjustment and significantly improved shot-to-shot consistency compared to traditional systems.

This component was specifically developed for VFC, APFG, and Maruyama GBBR platforms.

The internal design uses a tighter internal bore, dramatically improving FPS consistency within the approximate 0.9 to 1.2 Joule range.

Despite the narrower internal passage, the Crimson NPAS is still capable of achieving power outputs exceeding 2 Joules with appropriate setups.

Testing has also suggested improved gas efficiency compared to stock systems.

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 easy adaptation to field limits depending on:

• temperature
• gas type
• BB weight
• field regulations
