Note: By reading this, you accept the "Terms and Agreements" below.

Terms and Agreements:
Any pain inflicted by this "gun" or by your own idiocy while attempting to build the "gun" is not my fault. Deciding to shoot your friend/your toy/your pet/yourself is your decision and your decision alone, though there is always the influence of others. I cannot and will not accept responsibility for your actions, unless I, in any way, shape, or form influenced you directly within a distance of 10 yards (9.144 meters) of you to shoot your friend/your toy/your pet/yourself, etc.This is not a toy. This is a potentially lethal weapon.

This "gun" is built from two parts: the magazine/feed and the barrel (ram included). A couple of things you will notice about this "gun" are that it has no stopper/blocker/whatever the thing is called that stops the ram; it jams readily if not fired correctly (and if you just aren't lucky, but it is easily unjammed); by shotgun I mean 2 bullets at a time (you will realize how annoying this turns out to be later); and, finally and most importantly, the magazine is detachable (meaning you can remove it and attach a fresh one instead of having to constantly reload!!! OMGZORZ!!!!).

Note: Any list of required pieces is the list of pieces I used to build my version of the "gun." Certain pieces can be exchanged for others.

Special Thanks to: (your name here), an actual Instructables username, for the amazing magazine design. You will notice that I modified it slightly.

Step 1Constructing the Barrel and Ram

Constructing the Barrel and Ram

This is the easy part.

Ram:
1 black rod
1 tan clip connector
1 red connector
1 orange connector

Barrel:
2 yellow rods
1 red rod
8 orange connectors
7 red connectors
2 grey connectors
1 white connector

The ram is self explanatory.

For the barrel, just attach the many pieces onto the single red rod.

Please excuse the blurry pictures.

for #2 it is potentially lethal, here is a list of how it could be potentially lethal: you could beat someone over the head with it, you could stab them with a sharpened firing pin, young children could choke on the small parts, and they could be shot repeatedly until they go insane and go jump off a cliff somewhere or something. and it is semi auto you just have to add an orange connector to the firing pin and call it a trigger, then it could be semi auto. and who cares about looks? he only called it a shotgun because it has a spray.
May 31, 2009. 10:06 AMTigerNod says:
for #2: that's unfair :-(

It is not semi auto because you have to cock it before firing. This system is called a "bolt action gun" or "repeater". A block trigger does not change anything to that. (neither does a true one.) This is a semi auto gun: http://www.instructables.com/id/TrueSemi-automatic-Knex-pistol./

i mean't put an orange connector on the ramrod or firing pin, you would mount this to a bigger frame, and pull that connector back and let go to fire it, thus a crude, but effective semi-automatic shotgun.

That sounds awesome, but the reply is a bit late, eh? Look at the date, it's a year old!
Mar 23, 2010. 1:31 PMgeodez says:
now it's only 15 minutes old.

The other comment, the one from 2009.
Mar 23, 2010. 5:55 PMgeodez says:
i was talking about your latest one.
Mar 24, 2010. 5:35 AMTigerNod says:
And I was taling about the one from 2009.
Jun 25, 2008. 9:04 AMMr. Dudeness says:
Well if its a potentially lethal weapon, why build it? If I wanted something lethal, I could get my dads real 12 gauge shotgun or just use my compound bow and kill something. Now that's lethal.

i wish we had real guns at our house.

Honestly why would you play with knex at your age. No offence or nothing. Its still cool though. But sad aswell.

This is late, but they are fun.
Oct 23, 2008. 6:34 PMNinJa_RaiZer says:
potentially lethal??? sure. my best gun shot at like,i dunno,40 feet. If an airsoft gun at 300 fps. fires spherical rounds of about .2 grams 175 feet with a 11 gauge spring.i doubt that this could fire a round of like 4 gram rods hard enough to kill anything,but,hell, what do i know?
Oct 23, 2008. 7:14 PMMr. Dudeness says:
Oh jesus, I really didn't mean to start a big debate about all this, I completely forgot i had that comment and people are still replying 3 months later. Wow. Um, yea you go with your conversations then,i probably wont be replying anytime soon.
Jul 26, 2008. 11:30 PMDrWeird117 says:
and i could simply get my OWN (yes, it's legal to own one) PS-G1 converted(by me) to fully automatic.
