I am assuming its a level 7 bolt.
There should only be 2 orings. One behind the spacer and one on the power tube tip. Delete the one in front of the spacer, oil the heck out of it, dry fire it a bunch of times. If its still leaking then the spacer is not the right size.
Ignore the arrow in the photo. I couldnt find the stock exploded view in my files. The arrow is from a previous unrelated thread.
