Description
The GHK GMAG for M4/G5 Gas Magazine (GHK-GMAG-TAN) is a spare-magazine option for the platform identified in its model name. Keeping a matching spare ready lets you plan reloads around your loadout and replace a magazine that needs attention without changing your replica setup. The listed tan / fde finish identifies this version.
Loading and use
Use the propellant approved for your replica and follow its magazine-filling instructions. Align the gas bottle nozzle squarely with the fill valve rather than forcing it at an angle. Load BBs through the designated opening, keeping pressure off delicate feed lips. BB capacity does not establish the number of shots available from one gas fill; temperature, firing pace and the replica’s condition also affect operation.
Platform compatibility
Treat the M4 / M16 designation as a starting point for matching the magazine, not a promise that every brand or generation in that family will interchange. Compare the original magazine’s profile, catch position and feed interface. Check secure engagement and feeding with your specific model. Protect the feed lips during transport and choose a pouch that fits the finished magazine, especially for extended or drum versions.
