from a surefire website.

http://www.surefire.com/maxexp/main.pl? ... id=1524597

Mount — Clamps to rifle/carbine barrel or gas tubes from .5" to .9" in diameter
5/8 is in that range.
your problem is in the scope rings 1" =25.4. too small by a little for most scopes.

it looks like they have a stick on shim on the bottom of the ring to shim to 1"in the ebay pic.

maybe .

if not

If you had a ring to swap out probably would be best, easiest way to change ring size

lapping the ring w/ a sandpaper covered dowel or rod another way.

for what its worth
