|---|---|---|
| KWA / KSC MP7A1 GBB Series | Direct Native Fit | Direct OEM factory standard for KWA/KSC System7/NS2 MP7 platforms. Designed without a plunger assembly to align with fixed output valve positioning. Fine-tune the adjustable gasket height to establish an airtight compression seal against the loading nozzle assembly, ensuring smooth cycling and maximum gas efficiency without creating bolt drag. |
| Tokyo Marui / VFC / WE-Tech MP7 & KWA Rifle Lines | NOT Compatible | Third-party MP7 platforms and full-size KWA rifle series (LM4/MATEN) utilize distinct receiver dimensions, non-matching valve knocker strike depths, and proprietary gas router seal profiles incompatible with KWA System7 MP7 architecture. |
