This was inspired by revtiedye's "Gunzo the Great" Knex Semi-Automatic Rubber Band Gun so give some credit to him. I have noticed while looking for a knex gun instruction that none were really what I wanted. so I made it so you can change how you want your gun to be. I've made an assault rifle, a crossbow kinda thing, and a shotgun. this is a lot of fun for kids wanting to do a rubber band war in style! The pictures in here are for my assault rifle so follow along if you want my assault rifle or I can show you how to make your own customizations! sorry if the pictures are bad. I'm using a bad phone for the camera.

Supplies

You will need a lot of Knex for this

NOTE: This is for my assault rifle. the amounts may change depending on the gun you want to build

NOTE: I give rough amounts for the purpose of making this more on the customizable side. most gun with tis style would have the same supply list.

RODS

A decent amount of whites
An absurd amount of greens
A 20+ blues

CONNECTORS

a few light greys (2-slots)
4 oranges (straight 2-slots)(these are temporary)
2 purples (1-slot)
a few reds (3-slots)
a few greens (4-slots)
an absurd amount of yellows (5-slots)
8 whites (8-slots)

SPACERS

2 Baby blue (half the size of a connector)

That's all! Let's build!!!

Step 1: Parts for the Mechanism of the Gun

This is the only non customizable part. this step is almost none made by me. it is the guy I mentioned above.

NOTE: If you want to make a pistol I recommend checking out THIS.

Pic 1: These are parts that help hold the gun together.

Pic 2-5: This is the trigger

Pic 6: This is the rods that hold the spinner wheel and trigger.

Pic 7: MAKE 2!!! This is the gun case.

Pic 8: These are pieces for the handle.

Step 2: Assembly of the Mechanism

Pic 1: take the rods for the spinner wheel and the trigger and place them here.

Pic 2: Flip it over.

Pic 3: Grab 2 baby blue spacers and the spinner wheel and place them here. read pic note.

Pic 4: Place trigger here.

Pic 5: Add orange connectors to hold them in place

Pic 6: add these handle pieces here. see pic note.

Pic 7: work these handle pieces in.

Pic 8-9: work these handle pieces in.

Pic 10-11: remove orange piece and add other gun piece.

Pic 12: add these here.

Pic 13: make sure the trigger is outside of the gun.

Pic 14: Add rod here.

Pic 15: Add rod here.

Pic 16-17: See pic note. do this on both sides

Pic 18: add this on both sides.

Pic 19: make this.

Pic 20: add it here

Pic 21: put rubber band up here

Pic 22: add white rod here and tie it in place with rubber band from trigger

Pic 23: DONE!

Step 3: Seggment

This piece is great for customization. for this gun we will need 6 of these. Add more or less to the desired gun you want.

Pic 1. make this

Pic 2. Add these. put a green rod in between them

Pic 3. Do pic 2 again.

Pic 4. this is tricky. add this

Pic 5. do this on both sides

Pic 6. do this on both sides

Pic 7. do this on both sides

Pic 8. add green rods here on both sides

Pic 9. DONE

Step 4: Customize

Add as many segments to the barrel as you want. this gun has 4 plus a modded segment.

Pic 1-3. add a segment to the gun mechanism SEE PIC NOTE!!!

Pic 4-7 add 3 more segments. See pic notes

Pic 8-10: this is a modded segment that holds the rubber band. add this at the end of the barrel.

Pic 11-15: this is the same handle as before. change the segment to hold the handle where you want it.

Pic 16: i had not yet added the barrel so i did so in this picture

Some of the pictures got really messed up when i uploaded it. i fixed it best i could. Sorry.

Step 5: The Butt of the Gun

This is attached on the back of the mechanism

Pic 1-9 this is the butt. add it to the gun.

I was really tired so i didn't really work on this step much. leave a comment if you need help.

YOU ARE NOW DONE!!!!!!!
