Feed lips spreading/seperating causes it. A true double feed of live rounds that is.
Feeding an empty and a live is a dropped extraction and not a double feed. This is not magazine related.

No on the spring/follower (that was "armor" type of work). A bad spring would imply it is too weak.
The double feeds that I've see are due to a round "jumping" out of the mag as the spent case is ejected then the bolt strips off the now top round of the mag. It's a bitch to clear those as the round gets jammed into the gas tube area.
The other big mag failure I've seen is the catch wears out and the front end of the mag drops too low in the mag well and the nose end of the round hits the inside of the mag well. A slap on the bottom of the mag and it takes off.

Any carbines that really stood out?
What role do you think that cleaning and maintenance played?
What was the condition of these weapons? All things being equal, a lot of AR failures can be due worn parts.
