“So, I was given a "broken SLP regulator" for free, so I immediately went to find out what the problem was. the pin in the cap which pushes on the tank to release air is broken off. My first thought was to get this cap, but when it arrived, there was no pin inside. Upon further investigation, (just now) I found out this part is not supposed to have said pin. RIP.
Is there any way I can acquire the cap with the pin, or be able to send mine back?
Any help would be appreciated.”
Yes reach out to sales@ampedairsoft.com for returns/replacement.
It sounds like you need the whole UFA assembly with the pin:
