| GHK M4/MK18/G5 | Direct Native Fit | Purpose-built for the GHK M4/MK18/G5 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. |
| GHK HK416 / Umarex HK416A5 (GHK-manufactured) | Direct Native Fit (Shared GHK M4/G5 Magazine) | GHK's HK416 platform (including the Umarex-licensed HK416A5 built by GHK) runs on the same GHK M4/G5 magazine family, so this adapter installs and seals the same way. |
