I’m not certain where one can secure a semi auto rifle at this time. Perhaps wood stock hunting rifles are still available, but there is a serious run on those types of rifles that commonly scare liberals.
The ammo is scarce as well.
As posted above, keep an eye out for AK-47/74/103's etc...Romanian built WASR-10's are a great value and shoot some of the cheapest ammo in the world (because of volume production)....the 7.62x39 round, which is about equivalent to a 30-30 round...maybe a .308...
Stay armed, stay safe....
