I have a 1 Primary Clustered Index and the user created Non-Clustered Index. When I run a query and see the execution plan it uses the Primary Clustered Index (Index seek) but what could be the reason it doesn't use the Non-clustered index?

Thanks !

Because the optimizer thinks the clustered index will be more efficient.
