"I bought these O-rings for my brand new Walther PPQ, because it was leaking. So when i finally got them they would'nt even fit because they were too big. I bet these would work amazingly for other guns, but not for mine.

"Very happy with these. I have replaced the fill valve o-rings on my KWA KP8 mags (3 each) and my KWA KMP9 mags (2 each) and there is absolutely ZERO spilling from filling even starting with a full can of green gas.

They are somewhat difficult to replace, but I haven't had any tear like what people are saying. Comparing them to the stock KWA charging valve o-rings, they are much thicker and higher quality. I got plenty of leaks with the stock KWA o-rings but none with these.

Here are the steps I take to replace them:
1) Get a sewing needle and poke the o-ring and twist until you get and edge to pull it out.
2) Drop some silicone oil down into the valve.
3) Place moondog o-ring on top and use a pick (not very sharp) to spread around valve.
4) Drop more silicone oil on the top of the o-ring and test fill.
