Not always. I have two in 10/32" threaded rod.
You can choose from a choice of lenses, drilled for fibre optic, stuck on dot or circle, or blank. The circles provided are orange. I replaced mine with a black circle. Colours are blue, black or red. He might do a silver anodized but I've never seen or heard of this for the Titan recurve, and he only did it for the compound scopes for a little while.
They come in a little plastic tupperware container that has all the other circles/dots/fibres, instructions, and a bit of padding to protect it. Anything I've left out?
