Reading the description attached to the picture I posted is pretty funny. Obviously aimed at the un knowing...I did lots of river/water crossings and amphibious landings with me FN in hand. We carried them through thick and thin, no rubber replacements. Even the para training used a real rifle although they were the EX1/2s welded solid and barrels touched by torch. I never saw these and until the adoption of the M16A2/C7 never saw the rubber rifle. Now we have copies for everything but they still don't see much light. The example I show is the only one I ever saw, would have sworn they didn't exist.
