CTM HPA adapter for Hi-Capa pistols using M4 magazines

Do you love HPA setups and run a Hi-Capa pistol? Are you a pistol player who is not afraid to spam shots and standard pistol mags simply aren’t enough? Do you want to feed your pistol using AEG magazines for the M4 (AR15) platform? Or are you building the ultimate speedsoft setup? The HPA Hi-Capa adapter from CTM lets you use M4 AEG magazines (e.g., PTS EPM) with Hi-Capa pistols such as the SSP5, VORSK, Tokyo Marui Hi-Capa 5.1 / 4.3 and other TM-spec sidearms. It is the ideal solution for players who want to gain higher ammo capacity while fully eliminating cooldown issues caused by gas magazines. Thanks to precision-injected nylon reinforced with fiberglass and a steel magazine-well body, the adapter is lightweight, strong and durable. It is designed for HPA systems running 80–120 PSI. Pressures above 140 PSI may damage the pistol or the adapter. You can also read our article on how to assemble an HPA setup. This version additionally features an integrated anti-drop BB retainer and a lanyard loop for charms or accessories.
