Introduction: KNEX Bolt Action Horizontal Repeater Mech

Picture of KNEX Bolt Action Horizontal Repeater Mech


doesn't fire yet, and needs a firing chamber, but this is a demo of how a true horizontal magazine (think the p90) can be used wherein the rounds are positioned perpendicular to the barrel, and spun to allow them to be fired. Currently the mag holds 18 rounds of green rods, but it can easily be extended to hold more. this would be most likely positioned so that what is here shown as yellow and white connectors in rows would be where the top rail would be, with the bolt handle right behind it. I have no clue if anyone wants to use this in a gun, I might try myself but I don't know how I'll do. if anyone wants be to do a full ible on it for their gun, or even just internals, ask me in the comments and I'll do so. I'll post a video of it in action as well but I need to see if it has enough interest beforehand as my network is really slow uploading images and video. Cheers!

Basically after this just make the bottom guide for the bolt as a main part of the gun so that when the bolt comes back, it stops where the opening for the rounds is right lined up with the half-3d piece so that the rounds can drop down and get caught and spun.

Sweet I'm allready stripping my v.6 to add the mech

how well is it going so far?

I just posted mine

good luck! I'll update the mech for you...make sure the firing pin is inside the bolt as when it drops down it gets really unreliable. Make it like this (it even let's the bolt lock into place!) :

I personally hate removable mags they take up a lot of my parts

Knextremely stupid (author)2015-04-09

That looks amazing and probably pretty nasty to the guy ur shooting too

basically done with it now... I'm hopefully getting new bands tomorrow to test it out so I can post.

kind of a very extravagant secondary probably, especially with the non-removeable mag and such.

only shoots green rods, and is not all that powerful, but the really loud "chank-click" that the bolt makes when you move it is incredibly intimidating, and it looks like a really nasty shotgun. I think it's more a close range rapid reload kind of thing. maybe I'll add a pump too... :)

Knextremely stupid (author)2015-04-09

Ouch dude that's complicated I'll try to fit it though

here, my latest work :p

sorry... BTW I got a fairly reliable one just now. Looks pretty crappy and the trigger mech needs a lot of work but it fires, and actually pretty well

Knextremely stupid (author)2015-04-09

Once you have the 'ible up I will add it to my v.6 sniper and post (credit given where due)

here... as many as I could take and hopefully as many as you need. Feel free to offer suggestions! :)

I'll be sending a bunch of pics of the mech so far but I don't have much time to make an ible

sounds good.

Knextremely stupid (author)2015-04-09

The rounds shoot straight not sideways correct?

correct, when the bolt is pulled back one side is dropped down in, then pushed so it swings into a normal orientation.

Thx man instructables needs more people as creative as u

thanks! it's a lot of fun to work on

True dat.

Knextremely stupid (author)2015-04-09

Can u make an instructable on just the mech so I can build it I really want to build it

gladly... I'll do so after school today if I have time.

Knextremely stupid (author)2015-04-08

Can't wait to see how it looks

coming along nicely...

Knextremely stupid (author)2015-04-08

Why dint u just incorporate it into your dbar's frame

what I'm working on now...not going too well

Knextremely stupid (author)2015-04-07

Could u connect the two together so that when you pull out the bolt it cocks the pin but when you push the bolt back it leaves the pin cocked

Knextremely stupid (author)2015-04-07

That is good because all you have to do it put the mech higher that the stock and it will work

Knextremely stupid (author)2015-04-07

The bolt sticking out doesn't matter as long as it is above the stock because it will be pushed in anyhow

OK... need a cheek guard though as it wouldn't feel nice to have it whip by

Knextremely stupid (author)2015-04-07

Is the bolt part of the firing pin? Or is it like a bolt action where u pull out then push back in

currently they're separate

Knextremely stupid (author)2015-04-07

If I make the trigger handle section bigger in my sniper it might fit

the problem is how much space the bolt takes up when extended

OK, I'll see. IDK if I have enough parts if I don't take apart my dbar though

Knextremely stupid (author)2015-04-07

Some pics of the sniper and another idea I had was a bullpup pistol with that mag

Knextremely stupid (author)2015-04-07

I'm gonna try to add some close up pics but is night so might be bad

Knextremely stupid (author)2015-04-07

Well a lot of the parts r for the breech loaded internal mag mech and a simpler stock and sight can be added

Knextremely stupid (author)2015-04-07

Check it out

Knextremely stupid (author)2015-04-07

It will!! Try that

in your sniper?

Knextremely stupid (author)2015-04-07

Idk I'm not Good at building frames

Knextremely stupid (author)2015-04-07

Maybe an m-16 looking thing

or something like a spaz or something, just with a bolt

Knextremely stupid (author)2015-04-07

Wait a min imma gonna go check if that would fit in my v.6 sniper rifle

Knextremely stupid (author)2015-04-07

That entire mech includes the firing pin right

this is with the pin extended and locked with a very basic pin pull trigger
