Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| KWA / PTS Mega Arms MML MATEN .308 GBBR | Direct Native Fit | Direct OEM factory standard for KWA's large-frame System7/NS2 .308 AR-10 platform. Features an adjustable plunger to calibrate engagement depth against the internal heavy valve striker pin. Fine-tune gasket height to form a tight compression seal against the enlarged .308 loading nozzle, preventing gas bypass without binding the bolt carrier. |
| KWA LM4 / PTS Radian Model 1 GBBR Series | NOT Compatible | While sharing KWA's System7 gas engine design principles, standard 5.56 STANAG magwell dimensions on LM4 and Radian platforms are significantly narrower than the MATEN's enlarged .308 receiver housing. |
