Optics Covers

I have a Nightforce 5.5-22x56mm and I'm looking to get some butler creek flip-open covers but I am uncertain of which ones to go with?

I believe I get a #10 front because that's the 56mm one, but not sure about the back.

Does anyone know how to determine which ones to purchase?

THanks!
 
I need to get covers for the scope on one of my rifles too. I didn't think there was anything to know but the size of the lens.
 
Measure the outside diameter of the ocular (closest to your eye) bell and the optic (far end of the scope). You can do it with a mm ruler although it is a pain or you can use calipers. Then you can match your measurement with the cover chart to see which number you need.
