I have a mini 14, and I really love it but I wish I had an AR as well. I am currently saving up for a m&p 15 sport.. But with college and working part time, it will be a ways off :\
I am so glad I found this thread. My vision is terrible as well and I'd always worried about what would happen if shtf. My vision is so bad that if I didn't have my glasses I'd be good as dead, I am so near sighted that I can't see more than 6" in front of my face. Imagine if I had to survive...
I'll preface my post with saying that I don't own a large quantity of guns, and I don't frequent gun shops very often. I do a little reloading so I can shoot what I do have; however most of my reloading supplies come from online, as I have not found any shops that offer reloading supplies...
