Hate to say it but AR15, my most proven gun is my Delton carbine and one of the first I built. Proven, easy to maintain. Small parts pack for small parts...………..and a Ruger Mk IV target pistol accurate enough for game and small enough to pack. Eotech for immediate tactical needs and quality back-up sights that have a fairly fine aperture. Ammo is relatively light as are the Pmags.
Lets face it the first two guns you leave with will either be someone else's or you will be picking up someone else's depending on the nature of the event. You cant carry enough ammo to be sustainable.
