Introduction: Knex Rifle: Aggression Instructions

Picture of Knex Rifle: Aggression Instructions

Here it is. My first knex rifle.

So, first of all, thanks to Lucas the Boss for suggesting that my next gun be that of my own design, without that I don't think I would have gone through the work of building it. XD And credit to Red for the idea of stringing the bands over the grey gears.

So anyway, it is a simple pin, removable magazine rifle. Due to it shooting connectors, there is less of a problem with friction from the other rounds making the first few shots short range. The magazine locks into the gun with no need for tape to help keep it in the weapon. It also can hold 7-10 rounds. I prefer 7 rounds, for some reason. Pin pull is pretty good, but sadly, the pin pushes the round instead of hitting it, and as a result, it doesn't get the range it is capable of otherwise. I did not really test the reliability, but after 80 some rounds it has not failed me once. (Except when I tried to shoot blue rods out of it.) It also has some really nice sights of the aperture variety. If you want to know more about aperture sights, here you go. Length of pull is good, for me anyway, and it has a built in pin guide. (Yes!) It shoots a green rod+orange connector+green rod.

The handle is TD's and, I think that it fits well with gun.

The gun is also very well balanced.

Using two #64 bands it gets around 50 feet. The bands are not stretched much, and I can pull the pin back with my left hand... easily. (I am right handed.)

It has a very nice color scheme that fits the gun, and I love the looks.

In the instructions, you will see the cut off end of a rod. Do not use it! Swap it for a normal green rod, as this will increase pin pull slightly and make the trigger lighter.

Another thing is that you may see Killerk's pin on the gun. The problem with it is that the pin will disconnect from the pin guide. Use a pin like that on this rifleas this will work way better. One last thing, do NOT put the tan clip on the pin guide. I had it like this when I had a broken rod in the trigger, but since I changed the rod, the clip just hinder pulling the pin back.

So... #BuildAgressionNow

Sorry for the awful picture quality. I took some of the pictures at night, and I am never going to do that again.

If you have seen any of my other ibles, you know what will happen to you if you do not build. At the least, comment and subscribe, or you will be in trouble. :P

Step 1: Parts List

Picture of Parts List

OK, here is the parts list. I think it is accurate, enough to be very useful, anyway.

Green rods: 221

White rods: 77

Blue rods: 13

Yellow rod: 1

Black rods: 2 (They can be grey, if you don't have any black rods, but it will be a lot more prone to breaking.)

Ball socket joint: 1

Yellow connectors: 103

White connectors: 20

Blue connectors: 20

Green connectors: 14

Red connectors: 19

Orange connectors: 18

Grey connectors: 4

Grey clips: 18

Blue hinge halves (Should just be grey clips) 2

Y clips: 14

Tan clips: 4

Blue clips: 1

Blue spacers: 5

Cut white rods: 5

Size #64 bands: 6

TOTAL: 556

Step 2: Build These Parts.

Ok, read ALL the image notes. Sorry if it is confusing, but when I took the pics I was in a rush.

Step 3: BUILD!

Picture of BUILD!

Just follow the image notes. All of the notes don't make up for the bad picture taking, though. As for the two orange connectors at the end of the barrel, remove them. It seems to work better without them.

Step 4: Use.

Picture of Use.

Ok, take your magazine, and load up some rounds. Insert the magazine into the weapon. This may be difficult at first, but it becomes better with practice. As you can see, (hopefully) the green (In this case black) rod locks into the metallic colored orange connector.

decent gun. Nope, actually awesome.


JM1999 (author)2015-03-24

You should try building a snail mag next time!

This gun is awesome!

CorgiCritter (author)JM19992015-03-24

Thanks! You mean like a drum mag? That would be awesome! :)

JM1999 (author)CorgiCritter2015-03-24

Yeah, I think so...

One of those circular mags - I think we are on the same idea anyway...

CorgiCritter (author)JM19992015-03-24

Indeed. :)

I am going to build this when after I destroy my other gun.

Nice, I do have a better shooting version of this called Epidemic, just sayin'

If you do build this, use the trigger and reinforced back from this, and the stock internals from

it should work a bit better with those mods. if you have any questions or problems, feel free to comment or PM me.


Btw for some reason it has been snowing a lot in Texas lately. XD Never thought I would say that.


I was not expecting that...

CorgiCritter (author)2015-03-06

Thanks man! Something is wrong with the comment system, it says that you made the comment -417 minutes ago. XD

Yes, and you made your comment 8 hours ago :p

sandroknexmaster (author)2015-03-06

Looks awesome!

And you made this comment -467 minutes ago. :)

Knextremely stupid (author)2015-03-01

Awesome but I could see you adding a tubular mag and smaller ammo to it

I have thought of using a grey clip + green rod, but I don't think I am ready to attempt a tubuler magazine.

JonnyBGood (author)2015-02-26

Very nice! I like your angle with this gun, a clean performance based gun and I also like your building style and preferences towards mag locks.
Overall really like how this turned out, and I'd like to see what else you got planned.

CorgiCritter (author)JonnyBGood2015-02-26

Thank you so much! Yep, I like the mag lock. Tape is OK, but it sort of ruins the mag's looks. Not really a performance gun, at least not outdoors. Indoors it would be pretty good, but the round loses the accuracy after 30-40 feet, so no good for indoors.

Oh, and thanks for the subscription! I promised Lucas I would post his SMG, after that, I am thinking of some sort of bullpup hammer gun, as it is very hard to get a short bullpup with a pin.

JonnyBGood (author)CorgiCritter2015-02-26

I like that bullpup idea, and believe it or not that's how I started competitor V design. I just decided not to make it a bullpup after I found the body design. (The bullpup mech would have helped range....
lol I type a lot....
I say go for it!

CorgiCritter (author)JonnyBGood2015-02-27

Hammer guns can get good range, too. I was am using the phone app and so I don't have a link, but if you search "Knex hammer pistol," you should be able to find it. It is not the one Red reviewed,and it has couple "Made it " comments. Anyway, that little pistol got 50 feet FLAT. The way it shot gave the round some hop up, and so it was able to shoot far without an angle. (Sadly, if you shot it at an angle, it didn't get more range.)
That was the first time I realized that hammers did not need to just be novelties.

JonnyBGood (author)CorgiCritter2015-02-26

... And no problem on the subscription, don't want to miss any of your posts!

didexo (author)2015-02-26

Nice work. Personally I'd rather see more projects like this rather than reviews or postings of other guns. But none the less, nice job.

CorgiCritter (author)didexo2015-02-26

thanks, and I know. But it is hard for me to build stuff like this, and this is the first big gun I have built that really worked. I did promise Lucas I would review and post his SMG for him, but after that, I can try to focus on my own weapons.

didexo (author)CorgiCritter2015-02-26

Ah cool. Well yes it was hard for me at first but I promise it comes with practice, as most things do. I suppose building and reviewing those other guns helps as well, but not as much as building your own weapons. But that is gladdening to hear.

CorgiCritter (author)didexo2015-02-26

I agree with all that you said. :)

Zombiekiller-93 (author)2015-02-26

Very nice Corgi, I like the shape and design of it

Thanks, I like it too. X-)

TheDunkis (author)2015-02-26

Hmm, I like it. I do like your building style thus far. Sounds like the only thing you really needed to work on with this weapon is perhaps figure out a better trigger setup. Keep it up.

CorgiCritter (author)TheDunkis2015-02-26

Thanks! What do you not like about the trigger? It is light and strong. Is it the couple of broken rods? I really am liking your you handle, BTW, it is sturdy, comfy, and looks great.

sonic broom (author)2015-02-26

That's nice! but i wish it shoot rods i'm not that big of a fan connector ammo but i know some really like it. looks nice to! looking forward to some future builds.

CorgiCritter (author)sonic broom2015-02-26

I love both connector ammo and rod ammo. I prefer rods, as I have more of them and they don't break as often. Originally, this was going to have a removable yellow rod mag, but the way I ended up setting it up, I couldn't use a preloaded mag, which I wanted if it was going to shoot rods. Anyway, it can shoot blue rods, but it isn't as smooth or reliable or powerful. The advantage of connectors in a gun like this is they don't catch on each other and lessen range as much like a direct feed rod shooter.

As for future projects, I am planing on posting Lucas the Boss's SMG (I hope the pictures end up better then on this!) and I may try to get this shooting rods, but I will have to rip out part of the upper barrel if I want it to have a preloaded mag.

I can live with some of the problems rods have since I have so many of them. :D

Lucas The Boss (author)2015-02-25

Nice, I like it's slick design.

Thanks! I managed to keep the receiver and barrel pretty smooth, but on the stock I used WAY too many blue rods. I wonder where I got the two favorites...
