Introduction: Knex Rifle

Picture of Knex Rifle

Yes, the actual gun is a shotgun, as someone kindly pointed out. This is the shotgun from no country for old men. It shoots a maximum of seven green rods, or and rod for that matter. I think its four white rods, two blue rods with some space, two yellow (just) and a red or a grey rod.
This could well be my last instructable, because im putting my knex away for a while. However if I am inspired enough, then I may make another gun.
This is by far my favourite gun I have ever built.

Step 1: The For-barrel

Picture of The For-barrel

This is that big grey bit at the front of the gun, which holds all the ammo. I will take some pictures of other availabilities, as I'm sure a lot of you wont have enough yellow connectors to make my version.

Step 2: The Front Grip

This is where your left hand will hold and support the gun when firing, that is if you fire using your right hand.

Step 3: The Long Barrel

Picture of The Long Barrel

This is a barrel just like dsman197256's dd-27 but mine has a difference.
1. It's much longer
2. There are two grey rods in the barrel.
these grey rods are how the gun will fire. The firing ram is pulled back, the ammo rod pushes these two rods back, the ammo is loaded then fired. The energy transfers though the two grey rods, striking the ammo, sending the ammo everywhere, whilst the two grey rods remain fixed into the gun.

Step 4: The Barrel (continued)

Because it's that big.

Step 5: The Handle

This a handle that is really comfortable and supports the gun, both when carrying it, as the man does in the movies, and when you are about to fire then damn beast.

Step 6: The Body of the Gun

Picture of The Body of the Gun

This is just the rest of the body of the gun, such as the trigger unit and the barrel connections. The trigger mechanism is the same as my chainsaw rifle, as I find it easy to make and works quite well.

Step 7: Connections

This is where you can finally start putting everything together.

Step 8: Elastic Bands

Picture of Elastic Bands

This gun utilises a very good elastic band. About a foot long and half an inch wide.

Step 9: Damage

This is just a bit of the damge my gun can do.
Bearing in mind the box was full of rubbish and old toys belonging to my brother.

Step 10: And for Anyone Interested in Film.

Picture of And for Anyone Interested in Film.

I will be making the gas cannister the nice man uses.
it wont actually fire, but if you hold it up to someone's head,
then press the trigger, the ram will stick into that big head of there's.

I'm not going to post instructions, maybe a slide show.
Unless i get a high request for it.

i agree with the monkey, silencer dude

Dr MonkeyMan (author)2015-01-31

Pretty sure thats a silencer.

making master (author)2010-08-25

I have easily got enough yellows but not enough y connecters. good gun btw 4.5*. I give that result because theres no mag. But, I suppose it is a shotgun. 5*.

jimbob the great (author)2010-08-12

Any chance of a parts list because i reckon i have enough pecies but im ordering more anyway and just in case? And by the way guys change the subject!

thatonekid (author)2008-08-13

btw i hope all you kiddies know that there is practicaly no way to silence a freakin shotgun

mikstr2 (author)thatonekid2010-03-21

well.... they do it in mw2

thatonekid (author)mikstr22010-03-26

I apologize for the above statement, my brother commented using my profile, I do use proper grammer and i would apreciate it if you would start a new thread so that I do not receive an email every time someone puts in their two cents.

mr. cool 384 (author)thatonekid2010-07-14

well your bro is kindof rite that shotgun would not be easy to silence but a combat shotgun is a totally different storry they can ,with the mother of all silencers, be silenced

thatonekid (author)mr. cool 3842010-07-24

For God's sake, stop replying to the same thread! Go tell somebody else that my brother is right but note the above statement and stop sending them to Me! I get an email every time someone like you doesn't read the whole post and I'm tired of it!

mr. cool 384 (author)thatonekid2010-08-05

dont get you panties in a bunch

thatonekid (author)thatonekid2010-03-26

And the below statements.

zimster42 (author)thatonekid2008-08-30

to silence any firing pin-based knex gun, simply add a cushion to the part that stops the firing pin (i prefer duct tape and a bunch of kleenex, cut perfectly to keep the firing pin from hitting the gun, and yet not obstructing the firing pin)

An Villain (author)zimster422010-04-14

you also hear the sound of the pin hitting the ammo and the pin and ammo sliding along the barrel.

Nazgul (author)thatonekid2009-12-08

noo dude, there is actually.

j-chode! (author)thatonekid2008-08-13

Nope. I think it's silenced. When you hear the noise it makes, you'll see what I mean.

thatonekid (author)j-chode!2008-08-14

nope. I think it's HOLYWOOD!

j-chode! (author)thatonekid2008-08-15

Is it blessed?

thatonekid (author)j-chode!2008-08-30

what kind of question is that? it makes no sense!

j-chode! (author)thatonekid2008-08-31

"HOLYWOOD" holy wood. Hollywood has two "L"s.

lol good one

dj_nme (author)thatonekid2008-08-30

I haven't seen the movie, but there are two ways which a shotgun can be silenced.
1) Deer slug loading (ie: solid lead bullet) and using a silencer.
2) Captive piston type shot-shells which contain the expanding hot gases inside the gun. A similar cartridge design is used by the Russian Spetsnaz in a silenced assault rifle:

thatonekid (author)dj_nme2008-09-05

when you have tried and proven your idea i will believe you until the, there is no practical way to silence a shotgun!

dj_nme (author)thatonekid2008-09-05

Actually "silenced"is an exaggeration, the noise can only be reduced considerably. Hence these devices are properly called "suppressors".

Here is a suppressed shotgun, video on YouTube:

There is a discussion on suppressors here:

Whatever the thing was in the movie it sounded like a child's toy. You wouldn't be able to hear it from 10 feet away ...maybe.

Oblivitus (author)thatonekid2008-09-09

Yeah, it's pretty simple really, you just blow out everyones eardrums for 50 square miles, then fire. XD

j-chode! (author)2010-06-19

haha, im not really one to talk about grammer because i cba, but if you're going to having a go at someone at least get your grammer right first. "...proper grammer. you dont even..." capital y maybe? :)

metroidfan123 (author)2010-04-05

the yellow pieces are the most common so i'm sure people will manage.

kray953 (author)2009-11-14

kellykell (author)kray9532010-03-25

Grampa245 (author)KnexFreek2010-01-29

KnexFreek (author)2010-01-29

Do you NEED to make the thing with yellow connecters(with the 5000 yellow's)

Fred da Bunny (author)2009-09-02

bluelarz (author)2009-07-26

Dante9030 (author)2009-07-07

j-chode! (author)Dante90302009-07-07

nope (:

Dante9030 (author)j-chode!2009-07-07


j-chode! (author)Dante90302009-07-08

i think i modded my own version so it was pump action, but i never posted it.

roofm (author)2009-04-03

TigerNod (author)Owenmon2009-01-02

Dragunov owns, it's the AK under the sniper rifles.

j-chode! (author)Owenmon2008-11-29
