An alternative view might be that if it allows some old rifles to actually be used, in the field, for hunting, to be fitted with a scope, then that is to the good. All these lovely old rifles filling gun safes, sometimes hundreds for a collector to me is a great shame as well.

Some hunters still can and do use open sights. Many today don't or can't. I dread the day, when I can no longer use open sights. So of my rifles, are ONLY open sights. And would need new examples to be acquired to allow modern optics of some sort to be substituted.

Some old vintage rifles, especially rook rifles and those of smaller calibre, such as .22's of sorts, do really benefit from having modern precise aiming sights available. In my youth I could crawl a hundred metres to shoot a rabbit in the head at 7 metres. Not so today.
