| GHK SG553 | Direct Native Fit | Purpose-built for the GHK SG553 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 SG551 / SG550 | Direct Native Fit (Shared GHK 551/553 Magazine) | GHK's SG551 uses the same interlinkable gas magazine as the SG553, so this adapter installs and seals identically. Fine-tune the adjustable plunger height for a positive seal against the loading nozzle. |
