How to make the KTP (K'nex Twin Pistol)

How to make the KTP (K\
KTP is a dual barrel knex pistol, that has 3 firing modes:
Semi auto (Strong)
Dual shot (Stronger)
or Single shot (Strongest)

I built it as a sidearm, and it works great.
You can easily turn it into a rifle,
but I didn't have enough knex to add a longer barrel or a stock.

The single shot can put a quarter inch dent in drywall!
It help if you tape the ammo though....

Its semi auto mode isn't quite true semi auto, but it fires at the same rate as one.
You see, it has two triggers, side by side...

Let's get building!

IS this worth taking apart everything youve made out of knex?

Because its tempting to take apart my two way kex sniper/rifle.

I took my gun apart, built it, Just to find out that before completing the gun, i ran out of orange connectors.

Simple yet effective.

This is basically like my gun, but without the guide rails for most of the barrel length if I made it longer. ATM, my pieces are busy being in the D-TAB which I need to find the pieces to build the turrets for...

Now I have absolutely no reason to keep my first posted gun up. If anyone just begs me to put it back up, I will just link em here.

I liked this so much I decided to write you a poem. It's supposed to be a limerick. There once was a boy named bobizzle I'm not lying I'm foshizzle He got picked on in school and was not very cool his nickname was fofizzle
Jul 30, 2009. 2:34 AMTigerNod says:
Cool, but one problem. Have you checked out Oblivitus' ible on knex gun concepts?
Jul 30, 2009. 2:35 AMTigerNod says:
PS: The rifle version is just the same but with a huge stock attached, l0l
Aug 2, 2009. 2:29 AMTigerNod says:
But have you checked out the concepts? This idea was partly from me. And another part was from perfect duck ( http://www.instructables.com/id/perfect-ducks-quad-blaster/ ). I am not sure if you will have to give us credit though. Ah well, nice gun, 4.0 *

Dj Radio? I was talking about Perfect Duck.
Aug 6, 2009. 5:42 AMTigerNod says:
I see. Dj radio has some brilliant ideas, I must say.
Jul 5, 2009. 1:07 PMDJ Radio says:
A bit too late for postage, dont ya think?
Jul 5, 2009. 2:48 PMDJ Radio says:
When I say "too late", I mean that its been around for a while... I still like it and all...
Jul 6, 2009. 7:59 AMDJ Radio says:
nah, its similar to my first sniper, which is deleted.
Jul 6, 2009. 8:31 AMDJ Radio says:
Sure, but It was weak and flimsy structurally, and my OSSR renders it pointless to keep up at this point.
Jul 9, 2009. 11:20 AMJ Moneyman says:
u deleted it? it was piece efficient and was acurate with the added bonus of awesome range!
Jul 9, 2009. 11:45 AMDJ Radio says:
The range was really 40 feet. I made a guesstimated range back then, and overestimated by a longshot.
Jul 4, 2009. 8:27 AMJ Moneyman says:
sounds pretty kool
