Glock mag orings

[Pewpewpetie]

Hi all, got a second hand leaky Glock mag for my aap01 but looks like someone has changed out the o ring to the wrong size, hense why it's leaking. What size should be on here? Also shouldn't it be square? As I can't see a circular oring sealing the corners well. Any help is appreciated

It doesn't need to be square but TM OEM ones are. Options are if it's leaking from the base plate is to soak the rubber in silicon oil it should swell up to give you a seal. If that doesn't work Google Tokyo Marui/WE Glock rebuild kit. If that don't work your mag casing maybe warped and it maybe case of Ptf tape or worst case it's beyond repair. The other thing to think about is a rebuild kit is 10 to 14 quid that will give you enough seals to fix multiple mags or a TM mag can be got new for £25 WE for £22.

I have tried soaking o ring and also tried heating it whilst being stretched. It always leaked from the corners of the base plate

Could I use an instant gasket around the lip?
