Knex Concept Gun: Bullpup Bolt Action Repeating Slingshot
Intro: Knex Concept Gun: Bullpup Bolt Action Repeating Slingshot
Hello instructables! My third collaboration with blue mullet, and it's a big achievement! A bullpup bolt action, repeating sling shot. This gun was inspired by the cross bolt nerf gun. Many people over the years have been trying to make a repeating sling shot, the biggest mistake people made when building was putting the mag in front of the trigger. With this design, the slide pulls back the rubber band on to a trigger that is angled below the main barrel. Then a arm pulls the bullet out of the mag, over the trigger, and onto the barrel. Never before has someone made a repeating slingshot, that uses one single motion.
I could have never done it without blue mullet. He was not able to finish his because of his ball machine hornets nest. We brain stormed for hours on this mighty task. Long tedious hours of building with plastic, and shooting cats with nerf guns hehe (sorry I had to say it blue)
Hopefully this concept will be tackled by other users and Mabey one day take over pin guns.
Stats
It's a repeating sling shot!
Bullpup
Bolt Action
70 foot range
Shoots metallic clips and purple connectors
Very nice trigger
Comfy
Decent looks
Jams very little
Bolt come out the back of the gun :(
Hopefully this sparks some innovation back in the community. I will have a vid up soon and blue mullet should have one after his ball machine is complete.
Again special thanks to Blue Mullet!

Finally, my zipdart has been eclipsed :P
Great job dude, that looks awesome!
I've gotta get back into things again, so many new innovations since I stepped out--I might be able to use a couple to figure out how to get my pullpup idea working :)

Interesting concept. How high is the Rate of Fire?

Nice gun, like the look of it, I have a gun, hopefully posting it soonish, just got to finish it off. It is a remake of my NYG The other little project at the end of my bal concept post. I just haven't been posting anything new recently!

It may be a while, but I've said to myself that I will post it!

Excellent, now have it fire finned ammo, perhaps use a pump. Then you're well on your way to making a very war-worthy weapon. Also, for as small of ammo you're using, I think you could get away with not needing to have a bolt that goes out the back of the gun. The mechanism I imagined was an internal part that was pulled over the magazine with a rubber band. Then you'd use the slingshot band to push back this part, uncovering the magazine and letting a bullet out, and then sliding the bullet forward out of the mag until the band catches on the trigger. This could be done via a bolt or pump I imagine. Should improve reliability by removing complexity and isolating the mechanism inside the chamber. I'm sure other repeating slingshots have used something like this before.
Glad to see you're still building.

I don't see how giving it the bolt made it more compact. I was trying to save you space with the idea I presented. And what's your definition of a single action? I mean technically with a bolt, you have to pull it back and push it forward, two distinct actions, just in a smoother package. But that is better than two separate, unrelated actions. What are you working on next?
Oh I'd love to give it a shot when I get more pieces. Perhaps I'll try to make a proof of concept for a magazine and barrel design. I don't know if I can make a gun yet though.
