I had this exact problem and posted about it on Arnie's Airsoft some time ago:

You will need a LARGE screwdriver for this. I purchased one specifically for this purpose which doubles to screw in the plug for the CO2 powerlets. Find a flat head as wide as you can, Home Depot usually has them in the Tool Corral.

Once you've removed the bottom cap and powerlet, you will see the piercer module inside the mag. You'll notice it has two slots on the widest portion that a screwdriver will engage. Your screwdriver should be wide enough to only engage ONE side. Carefully unscrew it using the one slot (sounds silly but you can do this) until it falls out. Look at what you just removed and you will see the piercer assembly in the middle. You should then be able to unscrew the inner piercer assembly which has another two similar slots, and your screwdriver should JUST fit it to engage both sides perfectly. I took my magazine with me to HD to try different sizes until I found the one that worked. Unscrew the inner assembly and pull it out, being careful of the wire mesh that is easily lost.

Check all of the O-rings on the assembly. One or more of them may look okay but once touched will reveal many cuts and slits which renders it useless. Find one of a similar size and replace it, doesn't have to be exact (I'm pretty sure they're metric O-rings, an imperial will work if it's close enough). Carefully screw in the assembly again being mindful of the positioning of the O-rings, then screw the entire module back into the top of the magazine. Be careful with this procedure as it's possible for the screwdriver to slip off the one slot, and slightly damage it. I know from experience.

Hope this helps.
