Ian McCollum of Forgotten Weapons shows himself shooting an M11A1 with Max-31 upper at some steel targets. This is a course of fire that he has done often with many different firearms so he has a bit of reference data to compare this arm to others. The course of fire is not particularly suitable to full auto, which he notes, but it is still interesting to watch if you have six minutes to spare. He says that he will go back and shoot the same course on semi-auto in the next video.
