The broken line disclosure shown in the drawings encompasses two areas of the firearm sight: (1) the lower external portion of the design which is normally hidden from view when the firearm sight is mounted on its base, and (2) the internal portion of the firearm sight. The lower external broken line disclosure is not included in the claimed design because that portion of the firearm sight may take different forms according to the base the firearm sight is mounted upon. The internal broken line disclosure is not included in the claimed design because its size, shape, and orientation is determined by accepted industry standards.
