US Patent 10139211 Ammunition counter integrated into ammunition can

An ammunition can that provides a user with a count of stored ammunition, includes a housing and a window formed on one side of the housing to provide a visual indication of the count of the stored ammunition. The window extends from the top side to a bottom side of the housing, to provide a clear sampling view of the stored ammunition. A scale, disposed in close proximity to the window, provides a more accurate visual indication of the count of the stored ammunition.
