Knex Shotgun: Death Adder Instructions + Video




About: I enjoy archery, knives, and building weapons. I used to build with K'nex.


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.

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?

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.

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.

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?
