The difference between the Big Dot and Standard is only the size of the front of the dot.

The Big Dot is marginally larger for optical performance.

NOTE: When installing the fiber optic rod, use a small dab of crazy glue where the rod will touch the middle support of the sight. Do not put glue on the front support or the back support as it will be much more difficult to uninstall/reinstall the rod for future modifications. Each pack is supplied with 2 red rods and 2 green rods.
