Weapon Item Score

I am just curious…

Has anyone found any Weapon with an Item Score over 600?

Right now the highest number I have seen is 598 on a Sniper Rifle. Just last night I got to Promethea for the first time on TVHM. So I am curious if the Weapon #'s continue to get higher.

Had a 610 I think, maybe 601 Woodblocker leg hyperion sniper. I think that’s the highest in the game.
