(I am new to gbb and the following is my experience on fixing leak mags. If any of you find it trival, please ignore this post.)
I need to fix 6 out of 8 mags last month after winter hibernation (though they were all fed with gas + silicon to start with).
From my experience, WE use some kind of glue to secure the oring in place. Probably make it easier to assemble. Deformation (and leak) usually happen where they put the glue on.
All I did is to carefully remove any trace of dry glue (both on the oring and the cover), and put everything back together. That fix 5 of my leaky mags. The last one was a bit stubborn. All it takes is to put some black silicon (bought from Home Depot) around the O-ring. The oring did strunk a bit, but you should be able to stretch it by mount it on the mag cover first.
Lastly, (I read it somewhere from the internet), try use a clam or two, to hold the well aligned mag, oring and cover "tightly" intact before putting the screws back on. It helps a lot to avoid the oring got misalign while your putting on the screw one by one. And, it'll probably help avoid damage to the tiny oring around the screw.
FYI, the tiny screw sealing oring is of the following size, and it can be found from ebay
3mm I.D. (inner diameter)
1mm thickness
5mm O.D (outer diameter)
