UMAREX Glock 18C GBB Extended Magazine — Black

Extended gas magazine for the Umarex Glock 17, 18C, 19 and 19X GBB airsoft replicas (Gen3–Gen5), with a capacity of 50 rounds. Green Gas powered, metal body.

The 50-round capacity compared to standard magazines reduces the need to reload mid-game — a notable advantage on the Glock 18C in full-auto mode, where the rate of fire drains a shorter magazine very quickly. The extended format protrudes from the grip: shooters who prefer a compact profile will stick with the standard magazine, while those who prioritise sustained fire during a game will readily accept the extra length.
