I am looking for a good source of info for on rifles for a newby. I know zilch about rifles and ammo for them but would like to get one, maybe an AK47 or some kind of AR. Any good sites to learn about them? I want something reliable and easy to use and maintain. I guess I started to really think about it now that things may change. Also, sorry if this is a stupid question, are rifles only available in semi-auto?
