I've been thinking about getting a "survival" rifle to keep in the truck or whatever. I'd love one of the Springfield M6 .410/.22s, but I don't want to spend a bunch of money when it isn't going to get used a bunch. I've been looking at the Henry AR7. Are they worth it? The idea of storing it all in the stock is cool, but I've heard mixed reviews on accuracy and reliability. Would it be a better idea to get a Ruger 10/22 take down? What is my best option for around $300?
