RE: survival rifle
the things that i know i am sold on are
iron sights
semi auto
.223 7.62x39 .308 .30-06 .30 carbine most of these selections are bassed on price and availability. The amount I could carry would make a diifference so the 308 and the 30-06 would be second choice to some of the others.
synthetic stock
light and short would be important.
