2- #1 causes the need to clean the rifle often, not a great attribute for a battle rifle.
3- Too many small parts to be cleaning the rifle in the field.
#2 - -Granted the AR's in NAM did a lot of jamming, but that was after the issue of (what I call dirty powder) ammo.
#3 - With todays black rifles and using clean burning powder in the ammo, it would take not a lot, but a whole lot of shooting thru those rifles before an absolute cleaning would be necessary.
If I got into a firefight that required me to shoot that much, I'd more than likely be killed anyway.
Besides that, when I was in Nam, I never heard anyone saying they needed to clean their M16. Nor did I ever see a cleaning rod for an M16. That said, I don't see a problem with the AR15 as a survival weapon.
