Compatibility

|---|---|---|
| KWA / KSC M11A1 NS2 / System7 GBB Series | Direct Native Fit | Direct OEM factory standard for KWA's high-rate-of-fire M11A1 platform. Fine-tune gasket height to form a complete compression seal against the lightweight System7 cylinder nozzle without creating friction that slows down high-RPM bolt travel. |
| HFC / WELL / Legacy KSC M11A1 GBB Series (Pre-NS2) | NOT Compatible | HFC, WELL, and legacy pre-NS2 KSC M11 models utilize older gas system architecture with completely different release valve placements, output router seal profiles, and magazine catch notch heights compared to System7/NS2 specs. |
