I have a brand new, AI Impact Grenade leaking, I have triple checked the loading process with the pin. I even oiled it before putting it together just to make sure the reservoir was nice and oily. I have also checked the "reset/overflow" valve.

I have noticed that the gas is leaking directly from the fill valve, right after I lift it out. It's about a 3-5sec charge too, so I don't think I'm over filling it. I am using a metal one, but I have never had an issue with any other gas related items with filling.

What do you think the issue is with it?

Thanks
