Repair of scopes
You have to understand that in the modern business world where so much is made in China how Chinese Quality control works.
If they Chinese maker has an order for 10,000 units they make 12,000 and do not test any of them.
Then, if ABC optic brand who ordered these receives one back as broken or defective they have no way to repair it so they throw it away and send a new replacement. If they have run out of the optic, they will send the closest thing in their line or say sorry, that scope is discontinued.
I know this from experience. The global economy is so awesome...
