The question had already been answered from a previous media site.. See below for exact response to his private messaged question.
The Magnum was produced from 2010 - 2013 and were equipped w/ a slip joint. In 2013 CRC mfg the Tyrant which also had a slip joint. There were only a select few Magnum's that were mfg w/ the slip joint welded. These were by customer request only!
