I am REALLY tired of these clueless anchors talking about things of which they know nothing as if they are experts. Geraldo was just on F&F talking about how an AR15 is different from a Glock because you can simply "spray" with an AR15, reload, then "spray some more", whereas with a Glock you have to aim and pull the trigger. I have an AR15. I've looked a couple of times, and for the life of me I can't find the "Auto" selector on my AR15. Can someone please tell me how to make my AR15 fire fully automatic?
