[Stanks]

I just got a tank in a trade. It is a 45/45 Crossfire bottle with CP regulator. Upon initial inspection, the tank was empty because I just received it and I noticed the tank pin was not sticking out the top. I am wondering if this was normal for CP regulators or if there is something wrong with it etc.

I just brought the tank to the hydrotester because it needed to be done. I have read there have been a few small issues with these tanks including burst disk problems but I haven't seen anything about tank pins not activating.

If anyone could help, that would be awesome.
