CTM AAP-01 / G-Series 90° HPA Adapter for AEG M4 Mag - Violet / Green

90° HPA M4 Adapter for AAP-01 and G-Series

Do you love HPA setups and run pistols like AAP-01 or G-Series? Are pistol mags not enough for your playstyle and you want something with far more capacity? Do you want to feed your pistol using AEG M4 magazines designed for M4 (AR15) rifles? Or are you simply building the ultimate speedsoft setup? The CTM HPA adapter lets you run M4 AEG magazines (e.g., PTS EPM) in G-Series pistols such as SSP18, WE R17, Tokyo Marui G17 and of course the AAP-01. The 90° angled design offers improved ergonomics and stability when shooting from unconventional positions. A special internal mechanism prevents BBs from falling out while swapping magazines. For best feeding performance, we recommend using AEG magazines with strong springs. Thanks to precision-molded fiberglass-reinforced nylon and an internal steel magazine shaft, the adapter is durable, rigid and lightweight. Designed for HPA systems running 80–120 PSI. Pressures over 140 PSI may damage the pistol or the adapter. For more info, check out our guide on how to build an HPA setup.

Warnings

• The adapter does not include a pistol magazine shell – you must use your own.
