I am a 32 yr old female who is a self admitted wimp when it comes to the recoil and weight of a rifle. I am wanting to buy a "self defense" rifle for a civil unrest type situation. I want one that will get the job done, but that I can actually use. Obviously I am wanting something with cheap/easy to find ammo and High capacity mag availability. I also want it to be fairly cheap (under $500 used) and would love to be able to have a folding stock. Here are some that have been suggested by friends... ruger mini 14, sks, .223, and .243. I think that an ar or ak would be out of my price range at the moment. I would love to hear your opinions on these and any other suggestions you might have.
