That " Certificate of authenticty on the Weapon ".........is actually Tracking code of internal parts, serial #"s, etc that the manufactuer needs to comply with serialized military parts. This "UID" code is the key........I work for a Military Contractor and I use these daily.......Interesting though, where ever that UID is scanned, it knows its history, whereabouts and what needs replacing when this needs to Occur..........I think, not sure that the certificate is actually a paper enclosed in you Case.
