Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| KWA / KSC M226 P226 GBB Pistol Series | Direct Native Fit | Direct OEM factory standard for KWA / KSC M226 (P226) series utilizing the System7 / NS2 engine. 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 slide assembly. |
| Tokyo Marui / WE-Tech / KJW / VFC P226 & Non-System7 Pistol Lines | NOT Compatible | Third-party P226-pattern platforms (Tokyo Marui, WE-Tech, KJW, VFC) and non-System7 KWA pistol series utilize distinct internal magwell channel dimensions, non-matching valve striker placement, and proprietary gas router seal profiles incompatible with KWA M226 NS2 architecture. |
