That explains it, pros never have a clue as to what their equipment is
That's a regular 2k2 spec ironmen body that has been updated afterwards with alias (2005) parts.
The only markers that are 2.5s are the Ripper 2.5 and the Dragon 2.5; both are factory markers and not a random collection of parts as that ironmen is.
For $350 you can get something nicer.
