Friend keeps eying my AR and has asked me if they are legal to hunt with. As I am not a hunter, I am not sure about the answer but if I remember correctly, I heard that hunting deer was legal with an AR-15 but you could only have 5 rounds in the mag at a time. Is this correct? I did a search here but it seems that the word 'an' and 'AR' are too short for the search tool. Try typing "Hunting deer with an AR 15 and see what happens. Anyhow, is the 5 round rule true??
