Do you enjoy HPA setups and run a Hi-Capa? Are you a heavy-hitting pistoleer who won’t settle for standard pistol magazines? Do you want to feed your pistol using AEG magazines for M4 / AR15? Or are you building an ultimate speedsoft setup? The HPA Hi-Capa 90° adapter from CTM lets you use M4 AEG magazines (e.g., PTS EPM) with Hi-Capa pistols such as SSP5, VORSK, Tokyo Marui Hi-Capa 5.1 / 4.3 and other TM-standard pistols. It is the perfect solution for anyone who wants higher ammunition capacity and to eliminate cooldown typical of standard GBB magazines. Recommended operating pressure is around 120 psi, equivalent to Green Gas performance. Exceeding 140 psi may cause excessive wear to internal parts. The angled 90° design improves ergonomics and allows shooting from unconventional positions. A special internal design prevents BBs from falling out during magazine changes. For best results, we recommend using AEG magazines with strong feed springs. Read also our article on how to build an HPA setup: How to build your HPA system.
