Here is some info on the swim barrier fitted on the M2 through M2A2. The pics were originally posted by another member, razorblade1975 in this thread:
M2A0 Bradley Swim Barrier Reference .
The swim barrier was a rubberized canvas surround that was erected around the upper hull to give the vehicle more sideboard and allow it to swim across very calm areas of water. It was stored in the black, rubber tubing that is present along the upper hull of the Bradley. It was not very effective and a pain in the ass to erect. It was deleted on the M2A2 ODS version following Operation Desert Storm in the early '90s.
