This is my 1998 Autococker.  The list of modifications is extensive, but basically, there are no stock parts remaining on the marker.  I only had one barrel anodized to match - the Jacko Infinity series barrel that you see on it.  I also have a J&J straight-rifled HardChrome  8" barrel that is just awesome for speedball, and also looks pretty darn sharp on the marker!  You will notice there are two pressure guages on the marker - the one on the reg tells me how much pressure is entering the marker.  The one on the front block tells me what the pressure is inside my rock.
