I agree I was just using Private Ryan as an example.
Sorry - I wasn’t trying to hijack the thread. One of the best gunfight with rifles movies was Heat with DeNiro (lib), Pacino and Val Kilmer (dope smoking fat lib).
The shootout in downtown LA had M-16s/ARs and Pacino I think had a FN FNC 5.56 mm. Some people thought it was a CETME.
Here is a cool wiki site on the guns used in Heat. Good movie except one scene at the start of the movie was not cool. I will not mention what happened here in case someone wants to rent it.
