I need regulated builder's advice.I have a cartel revenant and the firing button stopped springing back into place. it just sat flush in the hole so i took it apart to see what was wrong. I found that the button inside clicked a razor thin metal popping disc like a saucer that pops down and pops back into place after you let go of the button. I got the disc popping again because the problem was that it didnt pop back into place. But i lost the metal popper and i don't know what its called or where i would start to look for one. So is there any store that i could go to to get one or would i have to order it? I tried searching on google for popping button metal contact, regulated vape mod button, regulated vape mod building parts, cartel revenant replacement parts etc. But i cant find anything at all to lead me to it just the firing pins for mech mods and how to fix tight batteries which is no help
