EPeS KWA/KSC MK2 GBB HPA Adaptor
The EPeS KWA/KSC MK2 GBB HPA Adaptor is a magazine adaptor that converts KWA and KSC GBB pistol magazines to HPA operation. KWA and KSC are a related pair of GBB manufacturers — KSC is the Japanese domestic brand and KWA the international export version, sharing common internal magazine dimensions. The MK2 HPA adaptor replaces the gas fill port with an HPA line connection, providing consistent output pressure from a regulated HPA tank regardless of ambient temperature or gas level in the magazine.
EPeS is a specialist HPA and GBB adaptor manufacturer. MK2 is the current iteration. For KWA or KSC GBB pistol operators who want HPA conversion at the magazine level rather than replacing the pistol platform, this is the correct adaptor for KWA/KSC magazine formats.
