Abstract

Firearm Optic Data Display attaches a Ballistics Data Display Card to a Firearm Optic using a slotted polymer U-Clamp and magnetic detachable Card Holder.

What is claimed is: 
     
         1 . A ballistics display apparatus comprising: a U-Clamp  1 ; a Card Holder  2 ; and a Ballistics Data Display Card  3 . 
     
     
         2 . A U-Clamp as in  claim 1 , wherein said U-Clamp is made of a solid polymer. 
     
     
         3 . A U-Clamp as in  claim 1 , wherein said U-Clamp attaches to a cylindrical portion of a firearm mounted optic by passing Guide Slot  8  over said cylindrical portion until said cylindrical portion is enclosed by Internal Diameter  9 . 
     
     
         4 . A U-Clamp as in  claim 1 , wherein said U-Clamp adheres to a cylindrical portion of a firearm mounted optic by elastic force generated when Internal Diameter  9  is less than external diameter of said cylindrical portion and Guide Slot  8  widthis less than Internal Diameter  9 . 
     
     
         5 . A U-Clamp as in  claim 1 , wherein said U-Clamp contains Magnet or Ferromagnetic Material  4  attached to or embedded in said U-Clamp. 
     
     
         6 . A Card Holder as in  claim 1 , wherein said Card Holder contains a Restraining Slot  6  providing overlap between said Card Holder and said U-Clamp. 
     
     
         7 . A Card Holder as in  claim 1 , wherein said Card Holder contains Magnet or Ferromagnetic Material  4  attached to or embedded in said Card Holder. 
     
     
         8 . A Card Holder as in  claim 1 , wherein said Card Holder contains a Restraining Slot  7  providing overlap between said Card Holder and said Ballistics Data Display Card. 
     
     
         9 . A Card Holder as in  claim 1 , wherein said Card Holder is penetrated by a Retaining Screw  5  for the purpose of attaching said Ballistics Data Display Card to said Card Holder. 
     
     
         10 . A Ballistics Data Display Card as in  claim 1 , wherein said Ballistics Data Display Card contains no mechanism for the purpose of attachment to a physical object.
