Rifle Scopes What Size BC Cover For my NF NXS 32mm Obj?

[1022rimfire]

Hi all,
I'm trying to determine the correct size Butler Creek lens cover for my 2.5-10x32 NF NXS objective. Does anyone one here know the correct size? If so, please share, I'd greatly appreciate it.

From another thread (for the 24mm obj), it looks like the ocular uses a size 13.

Thanks in advance!
