I already posted this in the vintage center-fire forum but I figured this forum would be more appropriate. I am trying to figure out how to remove the barrel on the 219 that I recently received after a family member passed away. It has the 30-30 barrel installed and it came with a 20 gauge barrel and forend. I removed the forend but I cannot figure out how the barrel is removed. Is it just really stiff to remove or what is the steps to remove the barrel?
