Can I take rifle scope (scope only) in checked luggage to India

Rifle Scope Imports are RESTRICTED

India restricts the import of rifle scopes, as per the list of restricted item downloaded from the Indian Directorate General of Foreign Trade website:

+---------+------------+---------------------------------------+------------+
| Item n. | Identifier |              Description              |   Status   |
+---------+------------+---------------------------------------+------------+
| 400.    | 9013 10 10 | Telescopic sights for fitting to arms | Restricted |
+---------+------------+---------------------------------------+------------+

Restricted items can be imported, provided one gets the appropriate authorisation from the governing bodies. This is all explained in the Foreign Trade Policy, which can be downloaded from the Download section of the Indian Directorate General of Foreign Trade website. It states:

Reading Material

The web is scattered with forum threads on rifle scope imports in India. One useful reference is this thread from Indian For Guns which roughly states what I have paraphrased above.

Legal Concerns

It is worthy to note that people have been previously arrested for attempting to illegally import rifle scopes in India. Granted that was an extreme case, but personally I would be wary of people online telling you to go ahead and put the scope in your hand luggage because you are unlikely to be checked by customs. Smuggling restricted items is a serious offence, and if caught you will be prosecuted.
