Rifle Scopes Vortex Defender Caps Sizes

Just figured we needed a size thread. Does anyone know which ones for the LRHS? Specifically 4.5-18?

The eyepiece cup only comes in one size, then you'll probably want the 44 Objective. The cups that contact the scope are rubber and pretty flexible so you have some wiggle room, but they pretty well run true to a scopes listed objective size. The cap is hard plastic. If you give the eyepiece cap a good swift flick, it usually pops up and lays completely flat. Love em.
