I always keep in mind that there is a good possibility that there are people that have little experience in this type of thing reading these threads and for them to get the impression that a 22lr would be an acceptable primary weapon in a SHTF survival situation is just wrong.
That's me. I've found this entire thread very interesting. We're learning the AR-15 platform now. Our next purchase was going to be something that eats .308 ammo, but a AK has been an interest for a while. I think we'll try both.
