I’m sure they are fine. Honest.
But this is yet another example of a historic brand name being misused.
B&S from the late C19th onward were a world-respected maker of optics. They specialised in things like rangefinders for Dreadnought battleships and submarine periscopes.
Eventually, they became part of Thales Optronics, who are still a world-leading maker of that sort of stuff.
Thales didn’t need the B&S brand name. So they sold it off to a bloke who now uses it to market Chinese-made value optics.
Nothing, I’m sure, wrong with them at their selling price. Just another example of a name historically associated with high quality and actually making their products themselves in the U.K. (Webley, BSA, Enfield, Lee-Enfield...) now being used simply as a marketing tool for products that have no connection at all to those that made the brand famous.
If Holland and Holland went bust, you could buy the brand name and stamp it on SMK air rifles, and you would (legally) be doing nothing wrong.
