OK, I got my solid top caps in today. Am I missing something obvious here? They each came with a tiny o-ring that I'm not sure what to do with. When I screw my adjustable post in, it seems to bottom out way shallower than my normal flat cap, and it doesn't go deep enough to make contact with my atomizer I'm putting on (usually I screw my atomizer in, and then screw the adjustable post in until it makes solid contact).
On top of that, if I then put the extension tube with the solid top cap/adjustable post in to my ELA with an 18350 battery, it has a noticeable gap (3mm or so) between the knurled locking ring and the bottom of the top cap. I can tell the battery is bottoming out and then the adjustable post is sitting on top of the battery.
I'm thinking I'm doing something wrong, and not using the adjustable post correctly with the new cap - and I think the likely culprit is the o-ring. Anyone else have theirs yet and can shed some light? I did have a long day at work, so my problem solving skills are pretty much kaput at this point.
Side note: They both look outstanding.
