Hey guys, I've noticed over the past few months a slight leak developed from my WE M92 (green gas) magazines which recently got so bad i lost a full mag of gas from the slow leak over the course of the game, after trawling YouTube i found this guy's video (link below) - tried what he suggested and it fixed the problem first time round, if anyone else us encountering a similar issue, try removing and oiling the filling valve o ring (flathead screwdriver to remove the valve) - if that doesn't work, follow what this guy does, worked for me first time and has been fine since.
