FYI, from Leupold website:
All Leupold riflescopes are given an individual serial number. Counterfeit scopes often use a fake serial number, all identical serial numbers, or incorrect numbering convention. If you find a scope that is suspect, simply write down the serial number and call 1-800-LEUPOLD to ask if the scope is authentic. In most cases, we can confirm a scope's authenticity by its serial number.
Leupold riflescopes are all designed, machined, and assembled in our Beaverton Oregon manufacturing facility. We do not have any other riflescope manufacturing facilities or offices anywhere in the world. So if you come across a Leupold riflescope being shipped into the United States from China, it is a very likely a counterfeit.
We encourage all consumers to protect intellectual property and combat counterfeits by reporting suspected counterfeits to
www.iprcenter.gov/referral or by sending us detailed information using the
Ask a Leupold Expert form and selecting "Counterfeit Issue" for the "How can we help you?" question.
