Introduction: Falcon Knex Assualt Rifle

Picture of Falcon Knex Assualt Rifle

This is my first knex gun i have ever built. I wanted to keep it simple, so you wont find much, if any innovation in this gun.
It features a sturdy, comfortable stock, true trigger, and a non-removable mag.
Here are some good old pros and cons:


-true trigger
-moderate range(40-50ft)
-moderate rate of fire(1 round per second)
-looks(thats my opinion)


-very heavy
-mag is undetatchable
-lack of inovation
-high piece count
-takes forever to load the mag(up to a minute)
-weak point where the stock meets the body

Step 1: Parts List (estimated)


tan clip-10
light grey-9
orange clip-2


pink (bendy)-3
yellow (bendy)-3


blue spacers-20
grey spacers-6
y connector-3
small black tyres-6
small black wheels (optional)-up to 12
2 small rubber bands
at least 2 big rubber bands

Step 2: The Stock

Picture of The Stock

Build the stock-simple step but might take over 10 minutes.

1-what you will be building
2-build two of these (only one should have the blue rods)
3-build one of these
4-build two of these
5-build this
6-build this
7-build this
8-combine steps 5,6,7 to make this
9-add one panel 4 to panel 2
10-add panel 3 to step 9 (note grey rod with grey connector and two blue spacers)
11-add the second panel 4 to step 10
12-add the second panel 2 to step 11
13- collect steps 12 and 8
14- attatch

Step 3: The Handle

Picture of The Handle

Build the handle. Should be very easy.

1-What you will make
2-gather these pieces
3-make this
4-make this
5-combine to make the finished handle

(you can also add black wheels to the handle to make it more comfortable if you want)

Step 4: The Main Body

Picture of The Main Body

The longest step of the instructable-should be easy enough though.

1-this is what you will build
2-make two of these(only one needs blue rods)
3-make two of these(white and blue rods should only be on one)
4-collect these parts
5-connect these two panels
6-add the next layer
7-the penultimate layer(long word =))
8-the final layer

Step 5: The Front Barrel

Picture of The Front Barrel

This is the front of the barrel-quick, simple step.

1-What you will make
2-make these panels
3-gather and make
4-combine one panel 2 to step 3
5-add the second panel to complete the front barrel

Step 6: The Trigger Mech

Picture of The Trigger Mech

Should take 2 minutes max to build. Very quick step.

1-build this
2-another view

Step 7: The Front Handle

Picture of The Front Handle

Almost exactly the same as the rear handle.

1-the finished handle
2-build this
3-make this
4-add them together to make the front handle

You're almost finished-hang in there!

Step 8: The Scope

Picture of The Scope

A very easy step, although attatching the tyres to the white connectors may provide some difficulty.

1-The completed scope
2-build these
3-attatch them with two red rods
4-make these
5-attatch them to the scope
6-finally, attatch the tyres

You're almost done now!

Step 9: Extra Parts

Picture of Extra Parts

Just some simple parts to make.

1-the ram it (you can also add tape so it can cope with more power)
2-the mag push.built it
3-dont know what to call this. but its very important so build it
4-finally build the bullets

you have built all the parts!!! Now for the fun part.

Step 10: Putting It Together

Picture of Putting It Together

Yaay! Lets put it together!

1-get the front barrel and the main body
2-put them together to make the main barrel
3-get the main barrel and the front handle
4-put them together to make ....umm... the main handle?
5-gather the main handle (not the actual handle!) and the stock
6-put them together to make the main stock (boy this is getting confusing!)
7-gather the main stock and the trigger mech (also get a blue rod with two blue spacers)
8-put the blue rod through the trigger mech and attach it to the yellow connectors
9-put the trigger up into the gun to get the main stock mechanism
10-gather the main stock mechanism and the handle
11-put them together to make the main stock double handle mech
12-now gather the main stock double handle mech and the scope
13-put them together (lets just leave it at that)
14-now attach the extra piece
15-and put the ram through it into the barrel
16-and get the mag push and put it into the mag

Congratulations!! You have built the gun! But there are a few more steps to make the gun fire.

Step 11: Adding Rubber Bands

Picture of Adding Rubber Bands

Now to add the rubber bands.

1-put a small rubber band here
2-put another small one on the trigger(but make sure it is strong) and put the big rubber bands on the y connector at the bac of the ram
3-where the two big rubber bands should go

Step 12: Loading and Firing

Picture of Loading and Firing

Ok now for the fun part!

1-load ammo into the mag
2-re-attatch the mag push and the rubber band so it is pushing all the ammo up to the top of the mag
3-pull back the ram

Then pull the trigger!!!

Step 13: Your Finished!

qwerty987 (author)2010-07-15

o o i know what it is it is a thingy for a gun

Skreetsha (author)2010-07-05

Since i had been off for like half a year, i don't have a bloody clue if i already seen this gun but i oughta say, very good job.

squarepants (author)Skreetsha2010-07-15

thanks-its nothing special really-very simple mech-i havnt built anything-off the site or from scratch-in about 6 months either =( -too much sklwork i guess-as well as too much xbox =p

KnexFreek (author)2009-12-19

 me gives this gun 5 stars !!!

squarepants (author)KnexFreek2010-01-03

 wow thanks! ive really wanted to make another gun for ages-this one is way to bulky and doesnt perform that well-but hardly have any time :( also short of ideas-maybe halo 3 shotgun with pump action?

Skreetsha (author)2009-09-04

YEAH! Sipriani V2 will always pwn the V3, weirdly enough... lol. And the R45 is great for beginning builders ;)

DJ Radio (author)Skreetsha2009-09-04

Times have changed since your Sipriani v2. That type of gun is less impressive now.

Skreetsha (author)DJ Radio2009-09-04

True, sadly enough..

DJ Radio (author)Skreetsha2009-09-11

You know, these comments have made me want to post an ible about my guide to success.

Skreetsha (author)DJ Radio2009-09-11

I don't think a lot of people will think it's necassery, so i wouldn't do it if i were you :/

DJ Radio (author)Skreetsha2009-11-04

I've been getting tons of questions about my success.  I thought I would post it when I retire.

Skreetsha (author)DJ Radio2009-11-04

Yeah, i guess so.
If people are asking you to, then do it.
I think you crawled past me on popularity btw.
I'm only getting like 20 comments a week.
When i built the Sip V2, i got three pages of 'em everyday.

DJ Radio (author)Skreetsha2009-11-08

Nah.  You still have higher ratings and more subs.  You just need to comment more.  I only get tons of comments because I make tons of comments.

Seleziona (author)2009-10-12

check out my vulture...

squarepants (author)Seleziona2009-10-24

 yeah it is pretty cool-your hand machine gun is better though-
i should really post my next instructable-its a dual-shot pistol, with a really strong true trigger and firing rod

Seleziona (author)squarepants2009-10-24

 ooooooh! sounds cool!

alfpwns (author)2009-09-01

id build... but i dont have anywhere near the amount of green rods needes

squarepants (author)alfpwns2009-09-13

hey by the way i'm making a small pistol that you'll probably have enough pieces for. Its actually more powerful, more reliable, and much lighter than this gun. I've just got to work on a few things before i post. it'll be 3 weeks max.

alfpwns (author)alfpwns2009-09-01

BTW 5*s and a fav

squarepants (author)alfpwns2009-09-02

wow thanks a lot! pity you don't have enough pieces though.

I_am_Canadian (author)2009-09-02

Looks nice! Good work on the handles.

thanks-that means alot coming from a great builder like yourself


DJ Radio (author)I_am_Canadian2009-09-03

I really need some of those black wheels for a gun I'm working on.

squarepants (author)DJ Radio2009-09-03

what for?

DJ Radio (author)squarepants2009-09-03

the handle.

squarepants (author)DJ Radio2009-09-04


DJ Radio (author)squarepants2009-09-04

Well nevermind, I found a substitute, only people say it isnt as comfy.

DJ Radio (author)2009-09-02

This is a pretty good first posted gun. Have you been playing with knex before ibles?

squarepants (author)DJ Radio2009-09-03

this really is my first knex gun i have made that has worked- my first designs were way to ambitious so i finally made something that i knew i could build. By the way i made lots of guns on this site before trying anything myself-that helped me to understand basic principles of knex guns and helped me to gain experience.

DJ Radio (author)squarepants2009-09-03

You could have just said yes.

squarepants (author)DJ Radio2009-09-04

yes but i wanted to bore you

DJ Radio (author)squarepants2009-09-04


knex mad (author)2009-09-01

that stock is the best stock ive seen looks very comfortable

DJ Radio (author)knex mad2009-09-02

Dutchj has a more comfy stock on his assault rifle. But this is good too.

squarepants (author)DJ Radio2009-09-03

It would be easy to use dutchj's stock on this, because it is the same number of panels wide-in fact id like to see a pic of the gun with dutchj's stock. It might look pretty cool.

DJ Radio (author)squarepants2009-09-03

You have a link to it in the last step!

squarepants (author)DJ Radio2009-09-04


DJ Radio (author)squarepants2009-09-04

Ohh! I misunderstood your comment. nevermind.

squarepants (author)knex mad2009-09-02

thanks again =]

Skreetsha (author)2009-09-04

Nice! Seeing this is your first gun, you did better then me :P And the stock looks great, smart of you using bendies. But tell me, how much rounds does the mag hold? Btw, faved and fived! A subscribement not yet, but keep going and i'll definitely sub :P

squarepants (author)Skreetsha2009-09-04

Wow!!! thanks alot!! But this would never compete with your guns lol. about the mag i think it can hold around 10 i forgot to put it down im sorry :[ Ive taken the gun apart now though so i cant check

knex artillery (author)2009-09-01

this gun looks great i especially love the stock and i hope to see more great guns from you

thanks-im working on designs for a pump action at the moment-not sure if it will work though

DJ Radio (author)squarepants2009-09-02

The most difficult part about a pump action is the trigger. If its a slide action then its easier.

squarepants (author)DJ Radio2009-09-03

yep i have found that out from a prototype-i tried using a true trigger that locked onto the end of the ram-and it almost worked! Next i will try to use a trigger maybe similar to the knexsayers block trigger. or maybe i will try making a turret gun-we'll see.

DJ Radio (author)squarepants2009-09-03

The knexsayer's block trigger was excessively bulky.

squarepants (author)DJ Radio2009-09-04

I know but it was a decent idea
