| Umarex / VFC MP7A1 GBB SMG Series (Navy / Foldable Foregrip V2 GBB) | Direct Native Fit | Direct OEM factory standard for the VFC-manufactured Umarex MP7A1 GBB series (1:1 scale platform). Fine-tune the adjustable gasket height to establish an airtight compression seal against the loading nozzle assembly, ensuring maximum gas efficiency and rapid bolt cycling without creating friction against the reciprocating bolt mechanism. |
| Tokyo Marui MP7 / KWA MP7 / WE Small Rice & Third-Party SMG Lines | NOT Compatible | Tokyo Marui MP7, KWA/KSC MP7, and WE-Tech SMG models are built to undersized scales (~90% scale) or proprietary internal engine specifications, featuring non-matching magwell dimensions, distinct valve striker locations, and incompatible gas router seal profiles with VFC MP7 architecture. |
