Indians For Guns

Today I went to buy a scope for my Scorpius.First went to aimco enterprise.There I was told that they don't have scopes in stock but they can arrange for a scope.Cost 1250.When I asked if the scope would get damaged with a few shots or change poi ,I was told there was no gurrantee , nor would they give a receipt for the item.
Next went to east India arms company.They had no scopes.
Lastly went to at daw & co.There I was told air rifle scopes are banned and if spotted with scope ar and scope would be seized by police.
Is this true?Are air rifle scopes banned?
Is there now no way to get a scope for a air rifle scope legally?

Nothing illegal about having a scope.

Thanks sir. I for the life of me couldn't understand how air rifles scopes could be illegal if the rifle was legal, especially since I am buying over the counter. Its real confusing when air gun dealers themselves misguide. Anyways thanks for clearing it up.
