Introduction: Jackal V4

You're not doing me a favor by building this gun.  I'm doing you a favor by giving you instructions for it.

Quick stats:
Range- 45-50 feet with 2 bands
Reload time- 5 seconds
Mag capacity- 8 oodammo rounds.
Very comfy
Very reliable.


Step 1: Outer Panels.

Make 2 of this.  Put blue rods on one of them, set the other one aside for later.

Step 2: Inner Panels

Make 2 of what's pictured.  Set one set aside, put one on the first panel.

Step 3: Inner Guts.

1- Make/gather these.
2- trigger closeup (REMOVE THE BLUE CAP)
3- combine this and the bottom of the barrel.
4- add it all to the gun.

Step 4: Inner Panels, Part 2.

Picture of Inner Panels, Part 2.

Remember that set of inner panels in step 2 I had you set aside?  Get them and put them on the gun.

Step 5: Outer Panels, Part 2

Add the final panel. 

2- Make this
3- add here.

Step 6: Handle.

1- make this
2- closeup on one important section.  This is for comfort
3- Add to gun
4- Make trigger guard
5- Add trigger guard
6- get them
7-8: add them to handle
9: get these
10-11- add to gun.

Step 7: Ram

Make the ram.  It's an orange connector, 2 gray connectors wrapped in tape, and a Yellow (in this case it's a gray metallic part) connector.

Step 8: Mag

Whee! Almost done!

1- Get all these
2- Make this
3- make these
4- Connect
5- Gather these
6- put them on
7- Add these to the gun
8- Add Etape.

Step 9: Loading and Firing.

Picture of Loading and Firing.

Just do it.

1- Take the pusher out and put it on one of the thingys.
2- insert 8 rounds of oodammo
3- Put a Y connector on the top
4- insert it into the gun.  Try to position it like I do for optimum power
5- Take the Y connector off and place it here.

Go have fun with your new gun.

Step 10: Troubleshooting.

-My mag breaks
A: Use tape on the mag area where specified

-I'm shooting 2 shots at one time!
A: If you are, they are most likely getting high range and they both have equal range.  Don't see it as a problem, see it as a shotgun pistol.

Time to celebrate:

The Knex Inventor made it! (author)2016-06-04

Built this a while ago. I think it was my third or fourth oodammo pistol.

ziggy.roberts.1 (author)2015-03-04

I need help with the ammo part, I cant understand the lics

WeNeedMoreCheese (author)2011-08-10

Super cool gun bro.

Anyways, I realise why people don't seem fond of you, but don't feel put off by that. Would you rather live in a world of Knexers who build great guns after criticism, or would you rather live in one where everyone is overpraising everyone in a world of happy smiley faces?

I pick the former, and I think most Knexers here would too.

~Meme~ (author)WeNeedMoreCheese2012-04-15

I do as well. Indubitably so.

The former is the community I came from, and the latter is the one it degenerated to. It's one of the main reasons we are having a lack of stuff that isn't generic.

peterson4 (author)2011-07-26

I built and moded epicly 25 round mag full stock and acog scope

apples!!!!! (author)2011-07-21

Oh, stop being a child.

travw (author)2009-11-15

Is the E-tape necessary?

DJ Radio (author)travw2009-11-16


travw (author)DJ Radio2009-11-16

Ok. Any particular reason?

DJ Radio (author)travw2009-11-16

The same reason you would put tape on a firing pin.

travw (author)DJ Radio2009-11-16

Yeah, I found that out.

~Aeronous~ (author)travw2009-11-26

 but i dont need tape on a firing pin, is it possible to just wrap a few bands around?

DJ Radio (author)~Aeronous~2009-11-26

It will still break.  You do need tape.

MegaMetal8 (author)DJ Radio2010-03-27

u dont on the ram

i put 2 yellow connectors then a small wheel
which i wrapped bands round
works good

when i didnt put bands on i broke two orange connectors :(

jonathanmi (author)MegaMetal82011-07-16

LOL i didn't need to put tape on firing pin and i works

MegaMetal8 (author)jonathanmi2011-07-18

Yeh same

jonathanmi (author)MegaMetal82011-07-18

Thanks first reply.

Raikou-san (author)travw2009-12-02

It holds the pieces together so that it won't break unless you put a lot of force on it.

Also, if that trigger breaks, you'd have to tear the gun apart to fix it. That's why there's tape on it.

jonathanmi (author)Raikou-san2011-07-16

I used 2 fat rubber-bands and it works. I did't use tape for the trigger and it works.

brentbrent (author)Raikou-san2010-07-22

if you dont use alot of rubber bands it wont break

DJ Radio (author)Raikou-san2009-12-03

He actually posted this on the "Mag" step.

Raikou-san (author)DJ Radio2009-12-04

Trigger was an example. First sentence was the reason for the tape.

jonathanmi (author)2011-07-16

Mine fires 2 but 1 goes far and the other just falls.

peterson4 (author)2011-07-14

I just got finished eith it an mi trigger is useless i think i did somethin rong help

SomeAsianKid (author)2011-06-13

dj i need help D: i wanna make a slide for my halo magnum that i built from knex gun builder (great gun btw) and i built the slide but when i pull back the ram, the thing connecting the slide and the ram snaps off, so basically im asking how do you make a slide that doesnt break off?

DJ Radio (author)SomeAsianKid2011-06-13

Very carefully. The best way is to use a setup like on Loosewire's slide action pistol.

SomeAsianKid (author)DJ Radio2011-06-14

100th comment ^_^ TY

arjun1 (author)2011-06-06

willdel545 (author)2011-02-19

DJ Radio (author)willdel5452011-02-19

Uhhh I don't know what state Lake City is in. Probably not, I've been in the same place for the past 4 or 5 years.

willdel545 (author)DJ Radio2011-02-21


DJ Radio (author)willdel5452011-02-23

What the hell makes you think I lived there at the time of the post?

willdel545 (author)DJ Radio2011-02-23

DJ Radio (author)willdel5452011-02-23

When I originally announced it I said the location was in Louisiana.

this is going in my bio

Im going to build this gun right now.

RedStark (author)2010-12-18

you posted this on my birthday :D

DJ Radio (author)RedStark2010-12-18

Merry Christmas.

xXxSubZero117 (author)2010-01-12

I don't have tape, rubber bands, Or anything on my mag. I have shot it well over 50 times already. and Either one of my mags haven't blown up. xD It has had a weird shot gun effect though. I'm assuming it's the strength of the Rubber band. But i'm not sure. Anyone else have that?

DJ Radio (author)xXxSubZero1172010-01-12

Actually 3 other people report a shotgun effect when using the gun.  I personally don't have this, my rubberband is a bit loose on the pusher.

mahmel (author)DJ Radio2010-11-27

What do you mean with shotgun effect? The ammo turns or what?

DJ Radio (author)mahmel2010-11-27

Shoots more than 1 per shot.

DJ Radio (author)2010-11-14

Please don't blame me if you can't build this pistol right.

ruben2597 (author)2010-11-14

Trigger doesn't work

DJ Radio (author)ruben25972010-11-14

Did you not see the video where I shot all 8 shots from my gun with no problem? You just didn't build it right.

DJ Radio (author)2010-09-15

Uhh You can clearly see it's attached to an orange connector.

dmytro509 (author)2010-08-25

great pistol i made it 5 star

jonnok (author)2009-12-31

 the front of the gun is so hard to make!! the instructions are hard to read (do)

DJ Radio (author)jonnok2009-12-31

Learn the basic mechanisms and how the barrel and gun works, and it will be so much easier. 

I'm too lazy to try any better.  Also I might have a hidden agenda.  I might be making these hard on purpose to keep noobs from building and screwing up the gun then saying it doesn't work.

Ok, I'm JK =P
