WE Hi-Capa GBB CO2 Magazine — Black

CO2 gas magazine for the WE Hi-Capa 3.8, 4.3, 5.1, P14 and WE M1911 airsoft pistols with double-stack configuration. Metal construction, fits a standard 12 g cartridge and holds 25 BBs.

The double-stack format keeps the compact profile typical of the Hi-Capa while providing enough capacity for CQB use or dynamic airsoft shooting stages. CO2 delivers more consistent pressure than pre-filled gas when temperatures drop, but requires a cartridge swap on every reload — slightly more involved than green gas, offset by more uniform ballistic output.
