My EV2 is a mark 1 from 2004.
I've tried floating the barrel and it's a mistake as far as my rifle is concerned. I now have the barrel secured into the action with the factory screws on top, and two M5 grub screws at 120 degrees, forming a 3-point pincer movement. Necessary only because the turned end of the barrel is an appallingly sloppy fit in the action.
I still have the factory figure of 8 at the front.
