So for those of you who don't know, and are interested in what separates a civilian legal AR15 from a full auto capable M4/M16 from a mechanical standpoint, I thought I would post a cool video I found that shows pretty well the difference.
The video is HERE
I found this video while doing some research to try to find out for myself what makes them different as I am quite familiar with the M4 fun switch , but don't have an AR15 to compare the internals to.
