Lens for riflescope question

[Featureless]

The scope is a Leupold VX-III. The rear (ocular?) lens is 37mm with female threads. All the lens covers/filters I can find have female threads. Where can I find a 37mm (polarizing?) lens filter with MALE threads?

Camera filter should work, as they're made to stack.

Make sure you're not trying to run a polarizer on front and back or you'll probably find yourself seeing nothing, unless they happen to line up.

I didn't even know this is a thing..
You mean something like this?

Bear in mind that a polarizing filter will reduce the light by approximately 1/2. Maximum polarization occurs at 90 degrees from the light source.

While a polarizer may help reducing reflections and will darken a blue sky, the light loss will not be helpful.

If you want to use a filter to protect the scope, use a 1A filter.

Some snipers carry polarizer for removing reflections from glass to see inside the room. But they dont leave them on the gun all the time.

Another thought:

I am a photographer. I rarely use any filters because even very high-end filters affect image quality. A filter on a rifle scope will do the same.

A 1A filter is a good idea in very dusty or raining conditions. Be sure to attach it to the objective on the scope.

If you do get a polarizer, be sure to get a 'linear' polarizer. The 'circular' polarizers for digital cameras will not work well on a scope.

I use B&W filters. They aren't inexpensive but are very high quality. B&H Photo has them in many different sizes.
