Do you mean Colt LE6920 and the Colt LE6940? Colt 6020 and the Colt 6040 does not exist as far as I know. One of the main differences between the Colt LE6920 and the Colt LE6940 is the use of a one-piece rock solid upper receiver that has a monolithic rail and a free floating barrel. In its flat top configuration, the LE6940 is also different from the LE6920 because the LE6940 features folding front and rear sights.
