Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| WE-Tech Bulldog / PX4 Compact GBB Pistol Series | Direct Native Fit | Direct OEM factory standard for the WE-Tech Bulldog (PX4 Compact) gas blowback series. 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 PX4 / HK3P Full-Size PX4 & Third-Party Pistol Lines | NOT Compatible | Tokyo Marui PX4 models and full-size WE PX4 variants utilize longer magazine bodies, different magazine retention catch placements, and distinct gas router height specifications incompatible with the compact WE Bulldog magwell architecture. |
