I got a new M4 a few days ago. I got to sight it in at the range today. This is a MUCH nicer weapon than my old Olympic Arms AR. Just to avoid any arguments, this is a home defense weapon and "AR" stands for "Armalite Rifle", the first company to offer a carbine rifle of this type.
Anyway, ....here's my shot group after I was done sighting it in. This is 25 yards unsupported. The stray round to the right was actually the guy on my left that shot my target by accident. (the difference between gun control and the lack there-of)
