Description
Upgrade your Tokyo Marui, WE, Armorer Works, KJW, or Novritsch SSP Hi-Capa pistol with the CTM Hi-Capa HPA M4 Magazine Adapter – Violet/Green, available now at Defcon Airsoft, the UK’s leading online airsoft retailer. This precision-engineered adapter allows seamless integration of M4 AEG magazines with your Hi-Capa platform, delivering enhanced magazine capacity and consistent gas efficiency through an HPA setup.
Constructed from glass-reinforced nylon with a CNC-machined 6061 aluminium release button, the adapter ensures long-lasting durability under demanding skirmish conditions. It enables players to use an HPA line and M4 AEG magazine, powered by a paintball air tank with a low-pressure regulator (0–140 psi), which replicates standard green gas performance at around 120 psi. As a result, users gain smoother shot consistency and reduced cooldown during sustained firing.

This adapter’s 1215MS free-cutting steel valve guarantees stable air transfer and long-term reliability. When combined with an M4 magazine featuring strong internal springs, users experience optimal feeding performance and reduced misfeeds. Avoid leaving magazines fully loaded for extended periods, since prolonged tension can degrade spring performance; replacement with superfeed springs is recommended when necessary.
Each package includes the Hi-Capa HPA M4 Magazine Adapter with rubber ring, 2.5mm x 100mm hex head screw with nylon gasket, and a universal feed tube for straightforward installation and maintenance.
Available in a range of finishes, this CTM adapter blends functionality with premium design, delivering exceptional reliability and aesthetics for competitive and tactical airsoft setups.
