    Unfortunately I haven’t been able to look into the Leupold Mark 5HD yet but hopefully, I’ll soon get the chance. The military version of this riflescope has just been given a NATO Stock Number or NSN.

    So what does it mean? Getting a NATO Stock Number means that your product gets a 13-digit code and becomes a standardized material (“stock listed”) and recognized by all NATO countries including the United States Department of Defense. There are also some countries that are not formally members of NATO but still use the system.Leupold Mark5hd tan
