WE Gas Magazine F17 / F18 GBB — Black

Gas magazine for airsoft, compatible with the WE F17 and WE F18 GBB pistols, with a capacity of 20 BBs. Metal body, black finish.

GBB magazines store the gas internally: as the gas depletes, the replica loses bolt carrier velocity and recoil consistency before the round count reaches zero — a reliable cue to swap the magazine. The metal construction keeps the weight and thermal behaviour close to the original magazine, which matters in cold conditions where a plastic reservoir loses heat faster and delivers lower output pressure.
