How To Make Semi Auto MAC 10 From Cardboard

In this video I make semi auto MAC 10 from cardboard.

I have developed a new semi auto mechanism for cardboard gun.
In short, it is "Finger Powered".

The bullet is located behind the latch, pushed up by magazine spring.
The bullet need to be pushed back a little bit in a magazine to pop up from a magazine.
The breechblock need to be pushed back manually at first.

When we pull the trigger, a latch in a breechblock pushes back a bullet against a spring.
The latch also goes up meanwhile and soon the latch release the bullet.
Eventually the bullet is fired by the spring.
Next bullet is pushed back a little bit at the same time.

And repeat.

Though trigger pressure is a bit high, it is still acceptable as you can see in this video.
