Do you guys work on palmetto jakls?  13.7 cut to 12.5?

no idea, never seen one. Does the barrel come out?

I think technically it does but from what I gather, it’s not an easy task, I’ll do some more investigating and get back with you

I think Josiah @Palmettostatearmory has said the barrel isn't removable.

Looks like it is per this thread.  Just a couple of tight cross bolts maybe?(guessing by the pics- no first hand experience here)

And allI’m looking to do is cut the barrel down, not swap or remove from the extension/trunnion.

If one was able to get the barrel out of the receiver(gas block and extension/trunnion still on the barrel) would that be able to fit in a lath to be chopped a little and rethreaded? Like a 13.7 or 14.5 cut to 12.5?

I'd have to see one in person.  With the gas block and the pressed on trunnion, we can probably thread it, but it would be very expensive compared to a standard AR barrel.
