Abstract
A magazine is disclosed including a storage tube and a biasing member positioned within the storage tube. A strip engages the follower and extends toward a distal end of the storage tube. A display member is coupled to the strip and is viewable through the storage tube. The display member displays a state of the strip. The strip may be coupled to the follower and wrap around an axle or spool engaging an axle. The display member may be a window such that a portion of the strip around the axle is viewable. The strip may include visual indicators that are visible through the window and indicate a number of rounds within the magazine. A switch may be selectively activated to illuminate a portion of the strip viewable through the window.
