MWS NPAS Quick Adjuster

Need to increase or decrease your FPS? Use this tool to adjust your NPAS without needing to disassemble your MWS. Simply pull back the bolt, insert the tool into the ejection port, align the hex key with your NPAS and turn the dial to increase or decrease the gas flow.

This works with most MWS and NPAS systems which use a 1.5mm hex key.
