Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| VFC SCAR-H MK17/APFG XM7 | Direct Native Fit | Purpose-built for the VFC SCAR-H MK17/APFG XM7 magazine well and feed geometry. Fine-tune the adjustable plunger height to establish a positive compression seal against the loading nozzle, maximising gas efficiency and feed consistency while preventing mechanical drag during the cycle. |
| VFC SR25 / M110 / FAL / HK417 | Direct Native Fit | These share the same VFC large-frame 7.62 magazine shell and feed geometry as the SCAR-H MK17/APFG XM7 platform, so this adapter installs and seals the same way. Fine-tune the adjustable plunger height to establish a positive compression seal against the loading nozzle, maximising gas efficiency and feed consistency while preventing mechanical drag during the cycle. |
Also sold as dedicated listings: VFC FAL HPA Adapter/Drum and VFC HK417 HPA Adapter/Drum — all four use the same magazine, so any of these listings will fit any of these platforms.
