The most noticeable difference is that the civilian AR15 lower receiver does not have the third trigger pin hole for the auto sear above the safety selector. The trigger pocket is also typically milled to different dimensions to prevent the acceptance of an auto-sear as well. However, this is not a rule. Many companies still sell their lowers with M16 trigger pocket dimensions, they are just missing the proverbial "third-hole".Drilling that third hole is what legally changes your AR-15 from a semi-automatic rifle, into an illegal machine gun.

You need a sear for that and possibly a lower. The sear can only be purchased thru a class 3 FFL.ATF Ruling 81-4In 1981, the
ATF issued a ruling that an AR-15 drop in auto sear in and of itself was considered a machine gun part and simple possession of it was illegal unless registered as a machine gun. Most importantly they also ruled that DIAS’ made before November 1, 1981 were legal to own.In 1986, the Gun Owner’s Protection Act also outlawed any part exclusively for use in a machine gun, regardless when it was made. Before that, a DIAS could technically be legally owned if it was made before November 1, 1981 and not possessed in conjunction with an AR-15.

Now, if you obtain one illegally that is against the law. Plus, nitwit, thank you posting what you did. One, you showed the weapon was NOT designed for battlefield use. Two, you showed you have to drastically change the weapon in order to do what is illegal, again showing the was was not designed for battlefield use. Third, this only applies to AR 15 Sporters which have not been manufactured in decades.
