Rifle Scopes Steiner T5 1-5 covers

[scsu74]

Hey all, my T5 came with the Tenebreax covers installed, but I was hoping to switch the ocular cover to a butler Creek flip open and the objective cover to their clear blizzard cover.

I measured 30mm edge to edge on the objective lens which doesn't line up with any of the BC sizes.

Anyone using one of the blizzard covers or can recommend a different brand that will fit?

Thanks in advance.
