The party you are trying to contact is an importer. These scopes are sold on Amazon and are manufactured in China.
The more product an importer is willing to import and hope to make some fast money on, the cheaper the importer can
purchase some items for.
Going the route some of these companies are working, they have no reason to carry spare parts. Some sellers will
state on their website for certain items, they will not accept returns.

Any Allen screws or bolts on items coming from overseas will be metric which in many cases does not match the metric
that may be used over here.

Some items being sold on the internet, the seller does not physically see or handle as they are shipped from some
warehouse or another country and the seller gets a commission for making the sale.

Wishing you all the best.
Take care.

Being this scope is manufactured in China is why the metric screws and bolts we have here will not work.
They have a different metric system.

Another example is the tools that Rolls Royce use on their air craft engines are called British Standard.
They are specific to their engines.

Wishing you all the best.
Take care.
