Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| GHK AK GBB Series (AKM / AK74 / AKS74U / AK105 / V2 & V3) | Direct Native Fit | Direct OEM factory standard for GHK AK receivers. Fine-tune the adjustable gasket height to establish an airtight compression seal against the loading nozzle assembly, ensuring optimal gas efficiency without causing drag on the bolt carrier. |
| WE-Tech / TM / KWA AK GBB Series | NOT Compatible | Third-party AK GBB platforms utilize distinct rock-and-lock lug dimensions, non-matching valve knocker strike angles, and proprietary gas router seal profiles incompatible with GHK-spec receivers. |
