Scope cover ?

I bought a new 111 with the Nikon scope , I have no idea what size caps I need , I don't have any way to measure them accurately, what size Votex covers will fit ? Thanks for the help

I would be really surprised if the threads on the Vortex covers match that of the Nikon scope. You might just have to trial and error them....

I'm talking about the flip cap covers , do they thread on ?

Haha the prototype covers I saw were screw on, but I just googled them and they are in fact slip on's.
If you go to Butler Creek's website, they have a size chart for most scopes. Use that information to choose your Vortex covers.

Thanks
