concept guns Answered

post any ideas for guns you have, and we'll discuss their effectiveness and ability.


https://www.instructables.com/id/knex-concept-gun/ its kinda like the dunkis concept

I am creating a gun right now. In a nutshell, it is very similar to solekill3r's El Diablo Gun, but it is an uzi with a completely removable clip, It loads by inserting blue rods into the clip and sliding it upward into the barrel. I's quite sick and the concept works on mlcad. Heres a pic. Note, the pic is only showing the hull/ frame.

I'm still trying to think up a design for a magazine and chamber where the ammo doesn't load straight up. In stead the ammo gets pushed forward out of the magazine into the chamber like in a real firearm. This would eliminate the jamming problems with rods and it would place the ammo up farther in the ultimately making the gun a lot stronger. This would eliminate the biggest problem with repeaters. My idea to do so was making a charging handle connected to a part around the pin just over the magazine. Then when you pulled back the handle to cock the weapon and you let go and it resets it would push the ammo out into the barrel. The only problem is you'd have to make either it or the trigger go around the other so that they don't interfere with each other. Probably wouldn't be too hard just making one like IaC's APs'.

solekill3r made a true bolt action sniper like that

I actually built a gun that had a top mag, and when you pulled the handle, the pin gets cocked, and the piece falls. Then, you push the handle forwards and the piece falls down into another chamber. Then, the pin goes off like normal. This had barely any power, and frequently misfired (the round bounced back up the chamber)

i tried that, the thing just breaks. knex can't hold the pressure of pulling the rubberbands back.

hmm..... i dont have the right roller coaster track pieces... sounds like a good idea in theory

the one thing is: there needs to be TONS!!! of power. Either use a huge ammount of knex battery motors (maybe 12?) to cock the pins, then at least 2 motors to turn the assembly. This gun will be HEAVY!!!

plus batteries (12 motors, @ 12 a pop is $144, plus the 2AA batteries, 1bout 16 bucks... holy $***!!!)

could somebody please rate this forum

It would be like the original ones. How do we create a mechanical release? Using a rack and pinion (sand off 1/4 of the teeth) would be tough on the gears, unless we use like four of them to distribute the weight, and then, using 6 pins would call 4 a huge action. I still like multiple barrels, but the firing pins will be difficult Let's look at how an airsoft gun works. It may not be what we're going 4, but could shed some light on the topic. I saw a video on youtube that could help. It is like the gatling gun animation, but I forgot the name.

I agree, and as I thought for a moment, we do need all 8 (I assume) pins. if there is only 1 pin, then the spinning barrels will obstruct it!!! We do need 8, and that will be a huge gun! Just a prototype would be as large a IaC's handheld cannon! For something this big, it needs good range, or else it is a huge waste.

You may be right, but by a prototype, just a small enough mechanism to pull back the pins, and have a rod leave the barrel. Who knows?

Ah, there you go. we would need like 4 gear trains, and multiple axles to support the load, but I think we're on to something.

thanks. I thought that there was just one pin. The benefit to a gatling gun is that it is much easier to align the barrels in this case. For each round, maybe half of a killerk gun barrel, then continuing to the end of the gun. However there is one vicious trade-off: Fast rate: weak Slow: strong Whatever works best, I guess.

what about a gatling gun that had a removable set of barrels?
you take them out and put the new ones in. to make it less pieces you could make them 8 or 16 barreled for each set.

RPG? (rocket propelled grenade)

a gatling gun seems ineffective to me. a chaingun seems more appropriate unless 1 firing pin is used, and that may require an alternate cocking method (model car motor?), but id like to see one made!

yeah. im not sure, it just would sound cool having a removable set of barrels. i dunno though...

it sounds cool, and if we could achieve the speed and the power, then it would save pieces. I saw a vid on youtube on how a real one works, and it may give you some ideas. I don't have the link, but it is an animation, and should be pretty easy to find.

I can picture the setup, but the firing pin would need to go off really fast, like use multiple motors to pull a string that releases at a certain point, or: each piece comes in a chink of barrel, with a rubber band on the front. Then, a motor pulls the band to the front of the barrel, and releases a trigger, senfing the bullet down the barrel.

that was it, and it may be difficult and inefficent, but hey, its just for the concept.

yep. it looks cool too. if we ever make something like that, we need to look at the vulcan nerf gun. that might help. also i would want to be able to see the action.

to knexguy, the trigger could be either a slingshot, and when the roumnd is added, the bullet goes off, or the way you suggested. to shadowninja: I see what you mean, and as for seeing the action, we would have to decide if it is worth the better chance of misfire, or if closed: harder to fix if it misfires.

yeah. i think seeing the action would be cool, thought it might be more prone to jammimg. if it wasn't visible it wouldnt jam so much but it would prob. jam worse when it did. yes i agree.

The only hard bits would be a trigger mechanism and creating the back/forward motion of the bolts, the could run on spiralling rails though. Oh, and the loading system could be buggy, with rounds falling out and the like.

I have an idea for a retractable sight, you pull the pin, and a sight pops up. However, it will require a lot of parts on the body alone.

why does it require lots of parts? I see it as killerk's srv1 sight on a rubberband-loaded arm that pops up when the pin is pulled out of the socket. btw, why a rectractable sight? one that doubles as a handle seems pretty useful.

you need a large-ish body to house the sight. not to mention the other parts. it would pop-up via springs beneath the sight. and its not killerk's sight.

not to seem mean, but whats the point? I see how it would work, and I imagined the sight either flipping up, or coming up like the screen on the Tmobile phone the G1 (google it if you anent familiar) out of the stock.
