Obscure air system trivia time 
OK... my goal is to extend a gas-thru grip that connects to a Mag VA. I need to drop it about 1" so I started thinking.
The tribal used to come with a toolkit that has an ASA pass-thru type tool thats only purpose was to provide a gauge port to measure the HP pressure. It was a female ASA/male ASA with a port for the gauge.
Tribal documentation called it a down regulator adjustment tool but that's not it's common name obviously.
What do you call these and who sells them?
