About: hello everybody plz take a look to my instructables and tell me what you think from them.

Hey guys,
this is my knex gun
it shoots more than 120ft !!
I think this is the most powerfull knex gun ever made, If someone knows a more powerfull knex gun plz send me a picture or instructable.
it shoots with 20 rubber bands and is very easy to make !!
if you want you can make the barrel even longer and use more rubber bands, it will shoot even further !! So stop reading this and get to work !


Step 1: The Barrel


This is the barrel, if you want you can make it even longer, it will be more accurate and it will shoot even further !!

1) Make this 2 times
2) make This
3) Add White Rods ( 4+5)
4) closer look left side
5) closer look right side
6) Add 1 and 2 together
7) add 1

Step 2: The Grip


This is The grip:

1) Make this 3 times
2) add them together with white rods


Step 3: The Trigger


The Trigger Is very easy to make !

Step 4: The Handle


this is the handle, I've tried to make it so comfortable as possible andI believe I have succeeded .

1) make these parts
2) add white rods
3) add the second layer
4) add the third layer
5) add the extra part
6) add small wheels

Step 5:

1) make this

4) add 3 to the barrel
5) add the trigger
6) add the handle
7) add blue spacers to the blue rods

Step 7: How to Make the Huge Rubber Band:

this is how to make the big rubber band you'll need for the gun.
you'll need about 20 rubber bands ( depends on the lenght of the barrel )

1-5)     tie the rubber bands together by five using the reef knot: this is how you can make it
6)         tie them together by five and do this 20 times
7-8)     put a rod trough the loops and twist
9)         It should look like this
10-14) add rubber bands as shown

    I made the gun, but how did you put the elastics on the gun

    it looks very nice, I think I am gonna make it!!

    also, if you move the wheels farther apart the ammo will go farther and it will be stronger

    hm, cool gun, but try to put a sniper scope on it
    then it will be more acurated

    can somebuddy can tell my how many yellow and green rods that the guns have

    I've made a more powerful one. Im in the process of making an ible right now. Just to give you an idea of my gun's power, it uses twin 3' bungee cords as propulsion, shoots rods at over 120 mph, has a range of over 300 feet, and can send a rod through 1/2 inch plywood if you sharpen the rod's end.
