The device encloses a ballistic data chart, holding it in place while permitting the user to view the ballistic data chart. The device is configured to allow the ballistic data chart to be removed and replaced to accommodate different ammunition configurations. The device is attached to the firearm in a manner that allows it to be removed from a firearm and attached to another.
