Introduction: 40mm K'nex Rifle

Picture of 40mm K'nex Rifle

It has arrived, the largest caliber knex rifle on Instructables. The beginning of this instructable will help teach you how to make a good K'nex instructable, like the instructable found here, but this one is an actual K'nex gun instructable, which may help teach you how to make a good one yourself if you did not understand mepain's instructable (which I have no idea how you couldn't, as it is written so well, but many of you seem to misunderstand it since bad K'nex instructables continue to use up bandwidth).

This instructable is broken up into four different steps, the first three describing the three sections of the rifle, and the fourth describing how to load and fire it. Notice how proper spelling and grammar is used, along with a diverse vocabulary. This helps you appear smart, even if you are not. Also notice how this gun has not been done before (i.e. similar barrel, trigger, or handle design,) and has a new (As in: never before used) trigger design. You may notice that the pictures are not blurry, and the instructable has a title picture, enticing the average everyday instructable user. This instructable also utilizes a unique title (As in: Not exactly the same as, or similar to, other titles.).

Step 1: The Back Section

Picture of The Back Section

This step is pretty self explanatory.

Picture 1: The butt from the side.
Picture 2: The butt from the front.
Picture 3: The rear sights and handle from the side.
Picture 4: The rear sights and handle from the back.
Picture 5: The rear sights and handle from the front.
Picture 6: The trigger from the side. NOTE: You use four fingers to pull the trigger.
Picture 7: The trigger from the back.
Picture 8: Insert the trigger into the front of the handle.
Picture 9: Attach the butt of the rifle to the back of the rear sights and handle.


Step 2: The Middle Section

Picture of The Middle Section

Easy, easy, easy.

Picture 1: The middle section from the side.
Picture 2: The middle section from the front.
Picture 3: Attach four orange/brown connectors to any side of the section.
Picture 4: Attach the middle section to the back section.
Picture 5: Push the trigger forward, it should click into place.

Step 3: The Front Section and Rubber Bands

Picture of The Front Section and Rubber Bands

This is a little more complicated than the last step, but still simple.

Picture 1: The back end.
Picture 2: The front end.
Picture 3: The top.
Picture 4: The front sights, you will attach these later.
Picture 5: Attach the end of the sights with the grey rod (the back) towards the back of the section.
Picture 6: Now the front.
Picture 7: Now the bi-pod. The picture is upside-down.
Picture 8: Add four orange/brown connectors to the back of the section.
Picture 9: Attach to the middle section.
Picture 10: Should look like this.

THE BANDS

First you must remove the first four rods on each side of the front section.
Picture 11: Cut a rubber band =(
Picture 12: Slide a dark grey rod on the band.
Picture 13: Now put three smaller rubber bands on each side.
Picture 14: Now you can tie the large rubber band
Picture 15: Eh, look at the picture.
Picture 16: Slide the white rods back.
Picture 17: Now put three more rods on each side.

Step 4: Loading and Firing

Picture of Loading and Firing

Yay! You have built the gun, now, (-_-) learn to use the gun you must.

Picture 1: I lied, you must build this.
Picture 2: Now build this and attach to the grey rod on the rubber band.
Picture 3: Now pull the piece from the previous step back to the rear sights.
Picture 4: Now put the piece from picture 1 to the piece from picture 2.
Picture 5: Make a shell and insert into the barrel of the rifle.

Now fire and put the trigger forward again and repeat pictures one through five of step 4.

concur (author)2011-03-20

Dose it fire

Whaleman (author)concur2011-04-29

Yes, it does fire. Look at "Step 4: Loading and Firing". It vaguely outlines the procedure for loading and firing this toy.

"Gah. Learn to Tripod."

Whaleman (author)The Jamalam2010-02-25
Gah. Learn to not necro. If you look closely, you'll notice that it was posted in 2007.

Besides, the error was more with lack of macro than anything else. Learn the problem before you sarcastically post a solution.
 
mettaurlover (author)2009-09-06

in steps 3 and 4, you got yourself mixed up a little. what you have is a grey connector, but you say grey rod. just wanted to clarify that for you

TigerNod (author)2009-06-20

I think the reason why Mepains guide isn't working is because people don't want to read it, because they realize that their "great super-powerful semi auto pistol" is nothing more then a "worthless super-weak muzzle loaded copy with a rod sticking out of it serving as a handle". So they just act like they didn't read anything and simply post it anyway. Or, it could just be they are just too lazy to read it.

Can I make a gun using this barrel system? (and give you credit)

Whaleman (author)TwistedParadox2009-04-12

Sure, go ahead.

g12345389 (author)2007-10-04

hey you u make things too big but it still awesome!

g12345389 (author)g123453892008-02-16
that a big ol 1.52 cal. (aka 152 cal.) wow my sniper gunna be .50 cal.(aka 50 cal.)

cause 10mm is 38 cal. urs 40 mm, 4*38=152 cal.

no such gun that big, they only rounds from a machine gun from a AC-130 (plane)
  • 1× 25 mm (0.984 in) GAU-12/U Equalizer gatling gun
* 1× 40 mm L60 Bofors cannon
  • 1× 105 mm M102 howitzer
Cannons up
Whaleman (author)g123453892008-02-19

1 caliber is equal to an inch. 40mm = 1.57 inches = 1.57 caliber. So close. And I call it a rifle because it is a 40mm grenade launcher, but the grenades don't explode.

g12345389 (author)Whaleman2008-02-23

the biggest REAL cal it .50 and my beret snipers will fire it the bullet it red connectors in that square way...(thats the closest i could get to .50 cal)

g12345389 (author)g123453892008-02-24

im making a Barret m107 it will own it the .50 cal

Millawi Legend (author)g123453892008-12-07

strato96 (author)g123453892008-11-02

Whaleman (author)g123453892008-02-24

Whaleman (author)g123453892008-02-23

I have seen .75 cal, 20mm and 30mm machine guns. The last one has a cartridge over 1 foot long.

g12345389 (author)Whaleman2008-02-24

no like handheld 1's(snipers, submachine guns, pistols, ect.)

Whaleman (author)g123453892008-02-24

There are 20mm anti-tank rifles, and 40mm grenade launchers can also shoot non-lethal pieces of wood, and lethal 40mm pieces of metal.

g12345389 (author)Whaleman2008-02-25

cool

g12345389 (author)Whaleman2008-02-23

w8 that is 1.58 that is 40mm were both wrong!

Whaleman (author)g123453892008-02-23

1.57480315 inches. How do you get 1.58?

g12345389 (author)Whaleman2008-02-24

wikipedia didnt lie it was on there they must'a rounded it and how u get 1.57480315?

Whaleman (author)g123453892008-02-24

google. It will convert metric and traditional systems of measurement.

g12345389 (author)Whaleman2008-02-23

im working on 1 of those rounds that are fired from shotguns and when it leaves the shell fins pop out and what it hit target it explode...

g12345389 (author)Whaleman2008-02-22

g12345389 (author)g123453892008-02-22

Cyclops Rock ~ They Might Be Giants ~ I taught you how to cyclops rock And then you go and turn around and break my heart And then you go and waste my cyclops time Mess up my cyclops mind I'm sick Like Chucky was sick My defeated heart keeps beating on I won't die Like Chucky won't die But I'm not here to socialize Gotta find a new place to hang out 'Cause I'm tired of living in Hell I'm a mess Since you cut me out But Chucky's arm keeps me company I'm a fright With my tombstone smile All the children run away from me Gotta find new friends to hang with 'Cause you're all afraid of me And I taught you how to cyclops rock And then you go and turn around and break my heart And then you go and waste my cyclops time Mess up my cyclops mind Dan! It was sweet Like lead paint is sweet But the after-effect left me paralyzed I just stare With my one glass eye Hoping you won't be back again There's a whole new generation Waiting to be wrecked by you I taught you how to cyclops rock And then you go and turn around and break my heart You waste my cyclops time And mess up my cyclops mind Pony, Twist, Monkey, and Freug These are the things that I taught to you Hitchhike, Boogie, Hypocrite Pop I'm stuck in a vat outside of New York AAAAAAAAAHHH! Taught you how to cyclops rock And then you go and turn around and break my heart You waste my cyclops time And I've got a cyclops mind

darth acexxacer (author)Whaleman2007-11-02

sammyb (author)Whaleman2007-10-27

how many long grey/black rods do you need for this gun

Whaleman (author)sammyb2007-10-27

12, I used the reinforced ones, but you can use regular ones as well. If you want the gun and the bi-pod you need 18 rods.

sammyb (author)Whaleman2007-10-28

thanks but i only have 4 :(
