I have never wanted an ar15 in 223 as I did not see the need. For some crazy reason I decided to get one. I now understand the love for a the 223. I hate to admitt it but the rifle is fun as all get out to shoot. I had the range to myself so I got to shoot at will and it was great. I will always remember how much distain, I have/had for the range commando dumping a thirty round mag into a target at 50 yards with no concern for other shooter. Another positive is I can come home with more brass than I left with. After working with 223 brass for the past few days I picked up a few 308 win. brass and they look fat.
