Piranha with ACI 6 stage expansion chamber, 16" cp barrel, E-dot on raised sight rail with beavertail, 12 oz. CO2 with smart parts on/off.
barrel, new bolt.
The gun was very solid and would be very hard to damage and is generaly easy to fix.
This gun was extremely un-reliable for me. It would double-fire, not-recock and break balls. I think it may just need a major overhaul, new bolt and a good barrel. I think mine was somewhat of an oddity though, and if you buy one and upgrade a few parts it should work great.
If you don't end up getting one of the cursed infernos, it should be fine.
