Night Force, uses brass internals,as I am sure some other good scope manufactures do. Those are the only 3 that I have torn apart ,or researched. Regardless of your choice,make sure the brands components are top notch.

I tore a Tasco apart years ago when somebody on a forum said they were junk because they had internal parts made of plastic. Like 90% of the crap posted by internet geniuses, they were wrong. No plastic parts to be found.

I tore my old leupold caps off and looked for myself. They were nylon.
