This is an easy 20min build Knex Gun, with a lot of power and an easy locking method*. It is very compact but still packs a nasty amount of strength! It is not a toy.

You'll need the pieces shown in the picture as well as 3 'standard' elastic bands or some reasonable equivalent. If the gun snaps often you can superglue the parts on. So let's get started!

*The trigger should fall down due to the elastic bands.

Connectors
13 grey
1 yellow
1 'hubcap' brown
2 red
3 orange
1 black joint
2 light grey
2 black 'square' joiners

Rods
4 white
2 red
1 blue

Spacers
6 blue (4 when using revised version)

If in doubt all will become clear in the following pictures.

I just gave him 5 stars for using oodammo in 2006.

bunduk deserves a high five. Using oodammo before it was oodammo.
DJ Radio says: Oct 7, 2009. 1:57 PM
So it isn't really yours.  I knew there was a gun that was using oodammo before you made it, but I coudln't find it.
oodalumps says: Oct 7, 2009. 5:16 PM
I was the one who discovered it's accuracy.

Also, even though I hadn't posted it on the internet, I was using oodammo sometime in october 2006.

Haters whose droning request for the list are much more annoying than block triggers. Copy and paste if you agree.
I_am_Canadian says: Aug 18, 2008. 10:39 AM
this was one of the very first guns...

As a beginner and on my irst visit to the site, this is my first gun and im impressed. mine doesnt bend its fine. if u could post a newer version for beginners with a real "gun" feel, thgat would be great!
Bright Shadow says: Mar 26, 2008. 1:16 PM
You're going to have a hard time looking for a realistic feeling gun. This is the most realistic one I've found
The Jamalam says: Jun 17, 2008. 10:28 AM
