Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| VFC M4 | Direct Native Fit | Purpose-built for the VFC M4 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. |
| APFG MCX (SURG / Spear LT / Rattler) | Direct Native Fit | APFG MCX models run on VFC M4/VMAG-style V2/V3/V4 gas magazines, so this adapter installs and seals the same way as on a VFC M4. 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 compatible with other rifles built on the same VFC AR15/M4/HK416 magazine pattern: Umarex (Elite Force), Cybergun, DNA (incl. T65), VFC VR-16, VFC SR-16, VFC Mk12, VFC Mk18, VFC CAR XM177, VFC T91, VFC FN FNC, and BCM x VFC.
