Rifle Scopes what size BC scope caps

[ericf]

Because I hate to have to return stuff, can some one tell me with confidence what size of BC caps fit the NF NFX 5.5 - 22 X56? I'm guessing a #18 oc. and a #48 obj.
Am I correct?

I saw that already, but the BC site list the # 51 dimensions that are way too large as compared to what the bell has been measured on the actual scope
