“Cite a source to the AR jamming please.”
Me. One year of Vietnam service using the M-16 which is just the full-automatic version of the AR. That ought to count for something.
Maybe the the jamming problems are fixed now, I can’t say. On the other hand, you could drag an AK through mud and cow dung, bake it in the oven, and chances are it’ll still fire. /s
Of course none of this is going to make one of those jam-o-matic drum contraptions work...and they don't magically work because they are plugged into AKs either.
