Lots of interesting comments, but many did not watch the video. The situation depicted is what happens when the rifle is unloaded, either after the clip is ejected, or when inspecting an empty rifle. Many describe the sequence when reloading a clip. This video shows what happens when you use your thumb to push down the follower.

One of the first things that the Army taught you was how to execute inspection arms when you brought the weapon to port arms, use your left thumb to open the bolt, and after the weapon has been inspected, you use the back of your right hand to push the charging handle to the rear and hold it while your right thumb pushing the follower down. At that point, you let the bolt go forward slightly over the follower, but still controlling the charging handle with the back of your hand until you remove your thumb. Then let the charging handle go and the bolt will spring forward into the receiver.

It sounds complicated, but its not that hard, and its seldom done wrong more than once.

Once is enough !
It'll draw blood on both sides of the thumb, and has been known to break the bone.

That’s the way we were taught way back in JROTC, 10-12 grades.

First time in drill formation, a week after being issued our M-1s, we had inspection. Uniform was khaki shirt and trousers with saucer visored cap, and white gloves. Three companies and there were a half dozen white gloves caught in the chamber, just hang there.

School yearbook photographer was ready with the Speed Graphic to capture the moment of shame. LOL!

And as you say, once was enough for that lesson.
