AirTac KWA F90 to M4 HPA Adapter (Modular, Fully Assembled)

This adapter allows you to run HPA with M4 AEG magazines on your KWA F90. 

Our M4 base is injection moulded using a highly impact-resistant polycarbonate blend.

We recommend the use of a PTS brand magazine such as EPM-LR, EPM1RX, EPM-1, EPM1S. Many other brands of magazine will work. If a magazine does not fit, you can swap the rear shim at the back of the adapter.

PLUG AND PLAY - We've injection moulded our own gas router for this adapter, and combined it with our high flow valve and printed feed lips. This means no more donor mags!
