how to remove the barrel

I picked up a Tech Force Contender Series 59 break barrel and the PO cut several inches off the barrel. Looking through the barrel i can see burrs where a crown should be.
There are 2 hex head screws attaching the barrel and i was thinking it could be removed and chucked in a lathe for a proper crowning job.
Is the barrel screwed on or just pressed fit and pinned with the 2 screws?
