This scope mounted design allows for a sleek and repeatable way to display your D.O.P.E. and other info on your rifle at eye level. Detents hold it open or closed. The interchangeable cards allow for quick and easy swaps between stages or engagements, and they can mount top or bottom.
Cards work with dry erase, wet erase or Sharpie markers to provide options for every environment. Sharpie can be removed with a damp Magic Eraser/melamine sponge.
