Do ARs have drop safeties? My understanding is that they do NOT. Meaning if a round is chambered, the trigger is forward, and you drop the gun in the right way, the firing pin can strike the primer and the gun can fire.
If that is the case, I would store it in #1. Agree that there will be time to chamber a round if you can get to an AR. My shotgun is stored the same way, full tube, empty chamber, safety off. A handgun is the only weapon I'd be comfortable storing with a loaded chamber, and only if it had a firing pin block (most do).
I believe I was wrong and ARs do have drop safeties.
