AirTac Archwick APC9K to M4 HPA Adapter — convert your APC9K GBB to HPA on M4 magazines.
The Archwick APC9K is a popular GBB PDW, and this modular AirTac adapter lets you run it on HPA fed from a standard M4 AEG magazine. That brings consistent shot-to-shot power and a far cheaper, more reliable alternative to chasing gas magazines around a cold game day.
The high-flow valve and feed lips come pre-installed; you reuse the gas router from an Archwick APC9K magazine to finish the build. The polycarbonate M4 base shrugs off stray BBs, and a swappable rear shim lets you fine-tune fit if a particular magazine sits loose in the well.
