Here is a Lego blowback gun. I won't be showing how to make it because it was very hard for me to build it, cause putting the rubber band correctly and the slide.

Step 1:

This guns slide can be pulled back to reveal the barrel.

Step 2:

When the slide is pulled back there is a lock to make it stay.

Step 3:

There is also a magazine.

Step 4:

These are the sights.
