TA11 Scope covers?

I’m looking to get a set of flip up scope caps for my TA11. Can anyone steer me in the right direction as to how I can mount one on the front? Do I need an ARD and a flip up cap and if so where can I purchase these items. I can get the ARD from trijicon, but what about the actual cover. Thanks.

Problem solved. I took a #9 objective butler creek cap, stuck it in the front as far as it would go then added some gorilla tape. Cheap solution that should work well.
