12 Gram Change Pierce Pin

[Hobbes]

I have a drop out screw in style 12 gram assembly, maybe an old Brass Eagle. I'm looking to replace the pierce pin but I'm not sure about compatibility. I see the Phantom style looks very similar, though the threads might be a bit different. I found a Daisy piece pin on eBay that also looks very similar. Can anyone point me in the right direction for a replacement that will fit?

Is it leaking? Probably easier to just replace the urethane seal rather than find a mystery pin.

It's not leaking, just barely punching open the 12 gram.

For future reference it looks like the pierce assembly from those cheapo Brass Eagle 12-gram changers is compatible.
