I filled the mags hours ago and I can still hear some of them hissing from the base from across the room.

Only option left I can see is to use JB weld silicone - so do I strip the mag bases, clean with degreaser, apply the jb weld silicone sealant, put the o-ring on, put the jb weld silicone sealant on the inside of the mags too - insert the base into the mag, insert pins, put a bit of gas in, leave for 2 days to cure = fixed?

Edit: will this stuff work?

You need blue gasket maker, put it on like the guide and let it cure for 24-48 hours.
