WE MP9 Big Bird GBB Gas Magazine — Black

Gas magazine for the WE MP9 Big Bird GBB airsoft replica, with a capacity of 22 rounds. It replaces the original magazine or expands your loadout for players who want more charges ready during game sessions.

The metal construction keeps the weight and feel in the hand consistent with the rest of the replica, and the gas reservoir is sized for standard Green Gas. The fill valve is accessible from the base, and the seals are designed to contain the leaks that typically develop after wear or frequent disassembly.
