Introduction: Knex Shotgun: Death Adder Instructions + Video

Picture of Knex Shotgun: Death Adder Instructions + Video


I appreciate your feedback about this, even if it is negative.

Yo Knex'ers. Me again, with my latest gat. A simple gun that can fire oodammo, fin ammo, or any rod. Capable of shooting 8 green rods at once, this is a indoor war beast. It has a pin guide to help keep the pin stable and a very comfy handle. Credit to Dark Owl as the front part of the gun is based on his TR. So get building. When my corgi saw it, he just tried to fall back asleep, so I dunno if I can call it corgi approved.




Somewhat piece efficient.

Quite light.

Looks decent.


Tube and stick barrel.

Shotgun or rifle in one.

Strong trigger.

Flexible, but not flimsy.


One cut rod.

Pin guide is not the best.

Slow reload if you use shotgun ammo.


Handles 3-4 #64s.

Oodammo shoots 70 feet with 3 bands.

Fin ammo range is untested.

Yellow rods shoot 70 with 3 bands.

8 green rods shoot 40-50 feet with three bands.

5 white rods shoot 50+ feet.

Does this have a magazine?

The Knex Inventor made it! (author)2016-06-04

Nice shotgun! I got it to shoot at least 50ft.

Cute dog!

Thank you, I'm happy it worked for you.

You are welcome! Yes, it worked great.

Awesome! and I love your German sheperd!

Thank you! He is actully a Corgi, but his coloration is different then normal. At least half the people who see him think it's a German Shepard. :)

knexcreator141 made it! (author)2015-05-26

This guns great it shoots at least 50 feet. good job man


Sorry I ment to put 70 feet

Good work!

sonic broom (author)2015-04-09

I may make this if i get the time. i'm going to get some cyber knex! today to use for the contest so i will be working with those for some time and then i plain to make some more guns after i get some other projects going. oh and how's your new gun coming along?

CorgiCritter (author)sonic broom2015-04-09

Cool! The pin guide on this is pretty meh, but in the picture see how there are two tan clips on a white rod? Make sure the tab on one of the is facing inward. This will keep the pin guide from moving as much. If you are willing to wait, my NAR Competitor has a better trigger, better pin guide, stronger barrel, and a more filled in stock. If you want the shotgun effect from this gun on my Competitor, just change the bullet lock to be like on this. I'll try to get the ible up right after the contest starts.

If the new gun you are talking about is my Competitor, it is finished, and if you are talking about my mini version of it, that is working very well. I want to post the Competitor first, so I can use parts from it to finish up the micro TR.

sonic broom (author)CorgiCritter2015-04-09

Are you going to call it the competitor if so it may be confused with Jonny's Competitor.

CorgiCritter (author)sonic broom2015-04-09

It is going to be named the Wrecktangle Competitor. (Yep, Wrecktangle is one of the NAR's many names.)

I really doubt it will be confusing. I take outdoor pics of all my guns, and my style and color scheme is different. Jonny doesn't even build competitors anymore.

sonic broom (author)CorgiCritter2015-04-11

Okay that sounds like a good name. i did not get the Cyber Knex after all I have to wait tell next week. So i will have some guns up after i finish some other Knex stuff. Also have you built the WASP from Red's pictures and video?

CorgiCritter (author)sonic broom2015-04-11

Good. I haven't built it, but I want to.

sonic broom (author)CorgiCritter2015-04-11

Well if you make it tell me how it works out for you. So I will know if I should make it.

Knextremely stupid (author)2015-04-06

New 'ible up my best design! so far the only breech loaded internal mag Knex sniper

Knextremely stupid (author)2015-04-06

Hey how do u upload a vid on an instructable

I have not embedded a youtube vid to ibles, but this might help.

Knextremely stupid (author)2015-04-06


Knextremely stupid (author)2015-04-06

Hey corgi when's the next project gonna be posted

Not until the knex contest, so in about a week.

akshat21045 (author)2015-04-04

~(._.~) (~._.)~
This is one cool gun... simple yet awesome!

Nice dog too :P what breed is it? I'm thinking German Shepard.

CorgiCritter (author)akshat210452015-04-06

Thank you! And you are not the first to think that my dog is a Shepard, lots of people think he is. He is a corgi, but with different coloring then normal. He is almost fully grown, actually. His name it "Spock."

Are you working on anything for the knex contest? You will probably end up with one of the prizes if you enter.

akshat21045 (author)CorgiCritter2015-04-06

Hehe he is one cute dog! I see why you got that name... (~._.)~

Yeah I'm planning on building some anonymous things for the contest, but I think that I won't make a weapon, well, not a gun atleast. It'll take some time, but I'll be over with it soon! I hope I win a prize again :P I still have my Roller Coaster from last year's contest. Let's hope you win too! You seem like a very promising builder by your activeness and designs!!!!!

CorgiCritter (author)akshat210452015-04-06


I will probably enter some guns, but I might try a 'practical' knex project, as those seem to have a good chance of getting featured or winning.

Knextremely stupid (author)2015-04-01

Hey fyi u spelled added wrong in title

Lolz, it is not spelled wrong, look it up.

nerfrocketeer (author)2015-03-29

You remind me a lot of DarkOwlProductions (Formerly DarkOwlKnex). He used to take pictures of guns in tree notches with photo filters and interesting gun names too!

...Are you his reincarnation? :P

LOL, nope. I kinda wounder what happened to him. BM thought that I have a building style like him.

As for names, I just don't care for when people name their gun. "My New Rifle" or "My Knex Gun."

And I just like pictures of guns in trees. :) I did get a love for filters and tree+gun pics from him, actually.

Haha that makes a lot more sense! DOP named his guns after songs though from some strange and obscure genre...

myOmy (author)2015-03-30

Love it. no simpler way to put it.

CorgiCritter (author)myOmy2015-03-30

Thank you! I have a better way to set up the pin guide, better add that to the ible soon...

Thank you!

Sweet! 1+

sonic broom (author)2015-03-29

This is looks rely nice do you have pictures of the gun with the mag at a weird angle i would like to take a look at it!

CorgiCritter (author)sonic broom2015-03-29

Oh, that? I was planning on taking pictures, but I forgot and took it apart. It was a very bad gun, the mag was not the right size for the whites rod ammo, and the trigger was sad. The mag fed the ammo patheticly, so it never shot right. The magazine was pointed away from the handle at 45 degrees because if it was straight there would be no room to pull the trigger. I kinda want to try again and get it working one of these days. Just imagine Viper with a red rod fp, bad trigger, and a white rod mag tilted away from the handle.

dr. richtofen (author)2015-03-28

Looks smooth and sturdy. The way you "attached" the front part of the tube barrel to the rest of the gun is pretty interesting, I haven't seen that before.
I can't really say something about how you could improve it, other than maybe a front grip or something. But that could always be added by others that build the gun.

About the ible itself, maybe you could bold the words pros, cons and other in the intro. Makes the separate sections a bit clearer, as every one there is immediately below the other.

Thanks! The front part is mostly Dark Owl's but I modified it a bit. Do you know what happened to him? He last commented about 6 months ago.

I wanted to add a grip like on Dunkis' UMP 45 Redone, but I was too lazy for that. I'll go and change the pros and cons right now.

No problem!
Haven't heard from Dark Owl in a while as well, so I don't know what happened either...

Knextremely stupid (author)2015-03-28

Looks amazing can't wait to see what u do next
