Knex Sawn Off Shotgun

This is my new knex sawn off shotgun. With 3 bands it can shoot around 40 - 45 feet. It is also quite piece efficient. So I hope you enjoy. If you have any feedback on my gun, post it in the comments and I will get back to you as soon as possible

Here is the piece count
57 green rods
43 white rods
4 blue rods
1 grey rod
38 yellow connectors
4 white connectors
4 red connectors
3 purple connectors
17 orange connectors
6 green connectors
3+ rubber bands
And that is the piece count. Please let me know if it is off.

The first band goes through the hole in the hinge and then onto the two pegs above the trigger. The next two go on ram rod. The first one goes on the second peg from the back. The next one goes on the fourth one from the back.
