A method and apparatus for configured to be attached to a gunbarrel of a firearm helping to aim at a moving target. The gun sight includes different-sized sight indicators including a first sight indicator located to be closer to the gunbarrel, and a second sight indicator, smaller than the first sight indicator and located to be further from the gunbarrel, both along a first direction that extends from the gunbarrel. In some embodiments use a plurality of different-sized of sight indicators along each of a plurality of directions for tracking moving targets approximately in those directions, for helping determine the amount of lead (the angle between the gunbarrel and the line to the target) used when shooting. Some embodiments use indicators, such as printed or embossed lines, icons, or tinted shapes, on a transparent substrate, while others use a wire-like structure formed with the indicators. Some embodiments use an anti-reflective coating.
