need help finding an accurate semi auto 223

[Rantastic]

does anyone have an accurate 223 semi auto they'd like to brag about??? I have been looking into the AR-15s and Mini 14 and really want one but im worried about the accuracy... I really need it to be a reliable semi auto and looks are immportant but not as much as accuracy. I'd like to be able to be taking coyotes at 500m and less.

Let me know what you all have and how you like them for the dollar... and if you do long distance shooting with them as well.

Thanks for any info.
