This HPA adapter represents the culmination of months of work to produce, from scratch, a shortened magazine and HPA adapter for the VFC M4. This leads to an ultra lightweight setup, that is both more enjoyable and economical than buying the gas mags.
Set PSI to desired recoil levels (usually 100+) and then adjust NPAS to get desired FPS.
An adjustable magazine release catch shim is included so you can adjust adapter height for air seal. Once your valve is in and sealing, do not tamper with or remove it. Some VFC have adjustable hammers that may also need adjustment.
Requires donor feed lips, gas router and valve from a VFC M4 GBB magazine. 416 magazine parts are the same and are also compatible.
Also compatible with APFG rattler
Features:
-
Compatible with most M4 magazines, works best with EPM and EPM1s
-
CNC Mag Release and Feed Tube
-
BB retention mechanism to reduce BB loss during magazine changes
