| Tokyo Marui FN Five-seVEN (FN57) GBB Pistol Series | Direct Native Fit | Direct OEM factory standard for the Tokyo Marui FN Five-seVEN (FN57) GBB platform. Fine-tune the adjustable gasket height to establish an airtight compression seal against the loading nozzle seal, ensuring maximum gas efficiency and smooth recoil recovery without creating drag on the returning inner slide assembly. |
| Marushin FN57 / Cybergun / WE-Tech & Third-Party Pistol Lines | NOT Compatible | Marushin FN57 models (CO2/6mm/8mm) and third-party pistol platforms utilize distinct internal magwell channel dimensions, non-matching valve striker heights, and proprietary gas router profiles incompatible with Tokyo Marui FN57 architecture. |
