I've got a Ego 05 and the bolt that it came with, I don't think is the stock one. I have a suspision that it's an early Cure bolt because of all the cut outs and detent saver notches, if you look carefully, the recess in the face isn't cut straight either. Have a look at the pictures and let me know. Also what, if any, part of the bolt should I be lubing and with what Oil or Grease?
