Umarex Glock 19 Gen4 GNB CO2 Magazine — Black

Spare metal magazine for the Umarex Glock 19 Gen4 GNB airsoft pistol, CO2-powered. It feeds the chamber with a standard CO2 cartridge and holds 11 BBs.

The metal construction ensures reliable gas seal over time, which is essential on a GNB system where every firing cycle vents gas through the magazine itself. A spare magazine lets you keep pace during a session without waiting for the primary magazine to warm up — a common occurrence with CO2 cartridges under sustained use.
