2.2" according to the Vortex site. Here's the link:

I measured mine with calipers and got 2.26" at the obj end of the scope, and 2.20" at the end of the sunshade. This would need a #39 Butler Creek flip-up cover.
If you are using a 1pc rail(like a Farrell or EGW) you will need medium Burris Sig Zee rings. If you are using 2pc bases(like Warne or Burris) I would go with high rings.
