Introduction: My K'nex RBG Machine Gun

Picture of My K'nex RBG Machine Gun
This is my K'nex machine gun. It shoots 8 shots , and shoots rubber bands. It has a wheel that you can spin at your own pace, and if you shoot them all at the same time it can have a shot gun affect, where the bullets spread all over. So, if you prefer a slow machine gun, a fast one, or a shotgun, this will be perfect for you.

Step 1: Barrel

1.) build (a)
2.) connect remaining yellow connectors
3.) build (b)
4.) connect a to b
5.) front view

Step 2: Middle

1.) build (a)

4.) connect a and b
5.) build (c)
6.) connect c to a and b (you will also need the barrel)
7.) connect as shown

Step 3: Firing Mech

Be careful! this step is tricky!
1.) build (a)
3.) build these pieces
4.) use a few of the pieces to build this (b)
5.) add on to a but do not completely snap it in!
6.) turn b around and add this piece
7-10.) turn back around and add this piece. snap everything in at the end.
11.) add to b
12.) build this
13.) take out a and put it through b as shown
14.) pushed all the way in
15.) different view
16.) add on the other orange connectors
17-18.) get out the last two steps and connect as shown

Step 4: Turret

1.) build
2-3.) add to gun
4.) different view
5.) gather
6.) build
7.) finished gun

Step 5: Loading

first, make sure the blue rods are pushed together, then add a rubber band from the front of the gun to the back on one of the spokes. do this until you have loaded as many shots as the gun can hold, or as many as you want, then pull apart the blue rods and let them shoot off at your own pace. so it can go fast or slow.

matstermind (author)2008-07-30

sorry but this is not a machine gun. it's an ok rubber band gun, but not my choice for wars or any other use.

Ikedog1995 (author)matstermind2008-07-30

yes i agree. its not exactly a machine gun. i know that but atleast it can shoot rapid fire without cocking anything inbetween shots.

paperninja (author)2008-07-30

arrow shot (author)2008-07-30
