Introduction: FX-9 (TAW) or Tactical Assault Weapon

Picture of FX-9 (TAW) or Tactical Assault Weapon

Here is the FX-9 Tactical assault weapon. This gun was designed as an all purpose weapon. It started out as my folding gun which you can see Here. .It didn't fire over 5 feet so I took it and tried to make it a sling shot. That didn't work either so I took it apart and made this. One of the things I like about it is that you can shoot any thing from a killerk bullet to a grenade and even a some of IaC's bullets. Another thing I like about it is the short trigger pull, and the smooth body as in no blue rods sticking out. The range depends on the bullet you use. I'll leave it up to you to decide if it's any good of not. Keep in mind the bipod type thing won't be it the instructions I just used it to keep it upright.
If it sounds good let's get a building.

Step 1: Part Count

On big guns like this you don't want to get 3/4 way done and run out of pieces. So I went and made a part count for everyone.

White 27
Blue 4
yellow 130 and 12 tabed
purple 2
green 13 (ooooo)
red 6
acute 6
orange 37
gray clip 4

red 6
blue 8
white 110 (one needs to be cut.)
green 300

Odds and ends
black hands 30

Keep in mind these are not exact but close.

Step 2: Front of the Gun

The instructions are pretty basic.

Step 1: Build two of these.
Step 2: Add orange connectors.
Step 3: What you should have.

Step 3: Barrel

Picture of Barrel

Just build this.

Step 4: Bottom of the Gun

Picture of Bottom of the Gun

Step 1: build all this and gather 4 white rods and 1 blue rod.
Step 2: put it all together.

Step 5: Put Together the Front

Picture of Put Together the Front

Step 1: take the side panel with orange connectors and add the part in step 4.
Step 2: now add the part made in step 3
Step 3: add the other side

Step 6: Back of the Gun

Picture of Back of the Gun

Step 1: Make 2 of these.
Step 2: add the blue rods and orange connectors.

Step 7: Make These

Picture of Make These

Here are some random parts. such as handle, trigger, etc.

Pic 1-2: handle
Pic 3: make this it will be the trigger.
Pic 4: this will be the ratchet.
Pic 5: make these parts

Step 8: Putting the Stock Together

Picture of Putting the Stock Together

Step 1: on the panel with the blue rods and orange connectors add this part.
Step 2: add the ratchet
Step 3: add the handle
Step 4: In the next three pictures add the parts that are shown
Step 5: This is what you should have
Step 6: add the other panel
Step 7: add these three yellow connectors in the butt.

Step 9: Put the Front and Pack

Picture of Put the Front and Pack

just put the two parts together.

Step 10: Loading and Firing.

Picture of Loading and Firing.

Put the rubber bands on the trigger.
put rubber bands on the barrel.
now to shoot the killerk type bullet, just string the bands on the tan clip and hook into the y connector.
to shoot the larger ammo hook the rubber bands on the y connector, set the ammo on top of the bands and pull the trigger.

Hope you all like.
If you have any problems let me know on my orangeboard.

ooo!!!! i like this gun, however, i can't help wishing it wasn't slingshot, because then it can't have a mag :( either way, this gun is sooo cool!!!!!! i like how you amde the gun smooth. 5*s

DJ Radio (author)knexsniper12009-06-21

there are slingshots with mags, those are pseudo semi-auto guns. But, they have a long reload time.

noobererer (author)DJ Radio2009-07-17

what about oblivitus' idea for a slingshot pistol/mag idea...i think it would work if some1 could work out the design

DJ Radio (author)noobererer2009-07-18

You mean the slide action sling?

noobererer (author)DJ Radio2009-07-19

yeh that one!

DJ Radio (author)noobererer2009-07-19

there are 2 things you would have to do with that. 1. make it so that the rubberband can get on the slide, and 2. make it go through the ammo.

Got it. I'll get working on it.

u just need to fix the 1. problem...the second u just need to make a mag with alot of friction so u just push the magpusher everytime to get the bullet up...unless u have a better idea, and GL!

I got a better idea. And I know it will work. If I can find the right configuration of parts.

sweet...if u r having problems with it message me and maybe i can help

Alright, I will do.

I may be able to help (with some advice) also.

Ya I'm not really working on that anymore. The freekiller was good enough for me.

:P Yea that gun is pretty sweet. I had that sort of idea awhile ago but I couldn't get it working properly...

I just got an Idea.

knexsniper1 (author)DJ Radio2009-06-21

i know what you are talking about. i guess those could count as slingshots. i still prefer ram rods over slingshots though.

Thanks. Ram rods are good in my opinion but I like sling shots better, cause of their long distances.

yeah, slingshots are way better for distance and scilence and accuracy, but sometimes it just feels better to hold a ram gun because it has a solid feel to it, know what im saying? another reason i like ram rods is because of the realism, because acutal guns have a ram, and slingshos sort of make the gun a little childish no? it seems more like a toy than a dangerous weapong. either way, this gun is amazing! :)

Jesus. (author)knexsniper12009-07-10

ok i will build it and shoot you and then you can see if slingshos sort of make the gun a little childish and if you still think it seems more like a toy than a dangerous weapon

knexsniper1 (author)Jesus.2009-07-25

im not saying that they aren't dangerous, im just saying that they sort of don't have as much realism. pretty much every realy gun, if not all of them, have some sort of ram to shoot the bullet. i know for a fact that they are lethal, but im just saying that i prefer ram guns.

knexguy (author)knexsniper12009-08-06

You realise real guns use a firing pin that moves about 2mm on average with not enough force to even move the round, right? It just sets off the primer cap.

knexsniper1 (author)knexguy2009-08-14

i know how a real gun works, but either way, i still prefer ram rods in a gun. nothing wrong with slingshots, but im just saying what i prefer

knexguy (author)knexsniper12009-08-14

I agree with you.

Jesus. (author)2009-09-16

5 * the only problem i can see is its so cool it just melted my face XD lol!

The Jamalam (author)2009-06-01

Bit too blocky, done before, only feature is its bulk. 3.0

knex_mepalm (author)The Jamalam2009-08-22

if all other weapons fail and your bands break, you can use this as a spear, or one of those things police use to knock down doors...

Mepain (author)The Jamalam2009-06-01

3 stars? That's a bit low, don't you think?

yannyboy (author)Mepain2009-08-15

lol jammys owned

The Jamalam (author)Mepain2009-06-02

No, not really. Nothing innovative, just very bulky. I'm doing the DGM thing.

DJ Radio (author)The Jamalam2009-06-02

Lol, hes owing you with your own phrases.

The Jamalam (author)DJ Radio2009-06-03

No, not really.

DJ Radio (author)The Jamalam2009-06-07

yeah, he is.

This should get at least a 4* rating.

The Jamalam (author)DJ Radio2009-06-08

I think this is Above average, but it isn't very good.

DJ Radio (author)The Jamalam2009-06-08

its better than you think....

The Jamalam (author)DJ Radio2009-06-19

He said it himself in the intro: I'll leave it to you to decide whether it is good or not.

You had to wait 11 days to find a good come back?? lol

And you had to wait a month to get a not so good comeback?

knexsniper1 (author)The Jamalam2009-07-25

settle down children

lioneatr (author)knexsniper12009-08-06


Who said I was trying to get a comeback.


Who cares??

Obviously you; you're replying.

Mepain (author)The Jamalam2009-06-02

The mechanics are innovative because they are slightly different.

Der Bradly (author)Mepain2009-06-02


Thank you sir.

cool bas3 (author)2009-08-20

An Villain (author)2009-08-11

Ha Ha, glad you like it. Did you rate??
