i think people are psychologically blinded by the malfunctions they experience. multiple times, I've gone on range trips with people, personally witnessed their firearms malfunction and them fix it and keep shooting, and later have that person tell me in all honesty that that particular firearm has been 100% reliable and never malfunctioned.
i don't think they were lying, i just think the chemicals in their brains are conspiring against them to suppress memories.
i have no other explanation for why i see dozens of malfunctions every time i go to the range, but everyone says THEIR gun never malfs
I agree with this.
In one instance a guy I know was shooting right next to me when he had 2 failures to fire out of 5 rounds. He was using very reputable factory ammo. He then warned me about that ammo, saying he had some failures to fire somewhat regularly. He totally blamed the ammo, even though it is a VERY reputable ammunition.
Then I took one of the rounds that failed in his rifle, put it in mine, and it worked.
He still says the rifle is perfect, and still blames the ammo.

I have only personally encountered one malfunction in my AR's. Mostly that is because I haven't shot them nearly enough. I'm at maybe 4k rounds total. The one and only malfunction was magazine induced using a magazine I knew wasn't the best, that I only used the range, that I no longer own.
With respect to AR's, when people use a good rifle, good mags, decent ammo, and LUBE the damn thing, they are exceptionally reliable.
Example: When I went to a Vickers class, the only rifle that malfunctioned, to my knowledge, was a new home build with a loose gas block (owner/operator/builder error). I think the guys there were maybe better than at the average range for selecting good gear, and lubing.
