Introduction: FN P90

Picture of FN P90

GLORIOUS !!! Finally the P90 you have been waiting for, many people have said that this may be a great P90, so l guess l'll find out how you guys like it. Wierd triggers are my trade mark so as the M16 this gun has one as well. It can shoot 20-25ft (that's the MAXlMUM range!!!) the mag is pretty awsome yet not, you have to shake the gun to get 5-6 shots then shake it again to empty the mag, the magazine has a 9 round capacity, but avoiding the shaking it works exellent. l also have a few accessories to put on it.

Step 1: The Body

Picture of The Body

We will now make the majority of the gun

1. Build two of these
2. Build two of these as well
3. You should have these now but with the spacers you put in earlier
4. Add the purple pieces
5. Add blue rods where shown on one side
6. Put on blue rods to one side
7. Add red rods to both sides of the body
8. Build these
9. Attach them
10.Get these
11.Add them on and it should look like this
12.Build these
14.Build these
15-17. Attach
18. Put these on
19. Add a red rod to it and through the orange connecter

Step 2: Firing Mechanism

Picture of Firing Mechanism

Here is what will make the gun fire

1. Build this
2. And that
3. A finished product (sort of)
4. Another view
5. Cocking mechanism
6. The rest of the ram
7. Build this with a yellow rod and don't put the black things on either
8. Here it is on
9. And there the barrel is in the gun
10. Add this
11. The trigger (build this)
12. Add these
13. Insert trigger
14. This is what it should look like
15. and here is another veiw

Step 3: Fore Grip

Picture of Fore Grip

This will be the fore grip
1. gather these pieces(3 blue rods will also be needed)and build these sub-assemblies
2. build this
3. add this on to the previous
4. add this on to the previous
5. and so on...
8. attach it to the gun
9. add the grey connectors

Step 4: Assembly Time

Picture of Assembly Time

This step tells us how to assemble the P90

1. here is what it should look like when the firing mechanism is in place
2. you should have this
3. attach one of the body panels
4. attach the other body panel
5. the gun is almost finished
6. this is optional, but if you want a little sight that is mainly for looks then put that white rod in place as shown...
7. then build this...
8. and stick it on like so

Step 5: Magizine

Picture of Magizine

this is what will hold the bullets

1. Follow the pictures
2. and so on...
3. Sorry that this last step is a little sketchy
4. and so on ...
5. now you will simply need to set those grey connectors on the mag as shown (they will later be taped on)
6. add that little structure on to the top of the grey pieces and tape it on (do the same with the other side)

To load the mag just put the bullets in (blue rods) until the magazine is full. Shake the gun once the magazine is in place (the ball bearing should be between the white and the yellow connector) with the barel facing down then cock it and shoot.

Before all hating, watch his video, it helps with a lot of your questions like how to fire the gun?
Here it is:

totoandamigo (author)2012-04-25

how does the magazine connect

Jedi_man (author)2011-07-25

NOOOOO! It uses 4 pairs of hinges!!! I dont have 4 pairs!

dr. richtofen (author)Jedi_man2011-11-20

use balljoints

Jedi_man (author)dr. richtofen2011-12-10

Eh... I don't have hardly any balljoints either...

dr. richtofen (author)Jedi_man2011-12-10

maybe green connectors, but it will probably strain them, or be weird and add an normal pistolgrip to it.

thehoyboy (author)2011-11-25

epicist knex gun ever

PiTBuLL892 (author)2009-10-10

miles510 (author)PiTBuLL8922009-12-06

gassybeans (author)miles5102011-06-11

how does this mag work?

kef4444 (author)leafydave2010-09-10

read it: To load the mag just put the bullets in (blue rods) until the magazine is full. Shake the gun once the magazine is in place (the ball bearing should be between the white and the yellow connector) with the barel facing down then cock it and shoot.

JB123 (author)2010-06-02

But how do u load it?

JB123 (author)2010-06-02

DJ radio leaves like a message on every gun and thats why he is so pro at this. he seems like a cool guy

TigerNod (author)cooldoodjak2010-04-26

And that makes him so pro? Where is that based on? No offense, but I think that's pretty shallow of you. A guy who makes cool stuff out of knex and listens to the advice of the public makes a knexer "so pro", you can not archieve that by posting one every instructable on the site.

A guy who is just nice to people in general is "a cool guy", though that is just opinion. (I don't think you even know DJ Radio anyways.)

A guy that thinks this way will only cause attention in knexing to go the the small group "elite knexers", and will cause innovative design from less-known knexers to go unnoticed. That will discourage these Iess known knexers to stop knexing and find a different hobby. I don't think you want that, no?

DJ Radio (author)cooldoodjak2009-10-07

I don't leave messages on every gun.  Only those that are worth me giving constructive criticism that will improve the gun, or guns that look awesome.

TigerNod (author)2010-04-26

Best Knex P90 EVER! I love it, 5 stars, totally yes. My only point is the part above the magazine: the part to mount the sights and optics on. This part should be just a little longer, and should also have support beams on the side facing the stock. And maybe some neat iron sights too. But other then that, don't change anything. It's almost perfect.

Andrew5909 (author)2010-03-20

green connectors worked fine for me because i only have one hinge connector.

brentbrent (author)2010-02-16

do you have to use the blue hingy thing?

knexjay (author)2010-01-30

is the mag pre loadable?

krazyfool (author)2010-01-28

 Just built it. I approve 4.5 from me

P.S i Never give 5 as EVERY design can be improved and its foolish to think it cannot be.

Mag cap is a bit low. Maybe extending front of the gun a bit more to accept a larger mag?

Im out of tan clips! can i use something else?

PiTBuLL892 (author)2009-10-11

hi me again.
i replaced them with ball joints and it works fine
but the trigger jams alot
so im trying to develop a different trigger

darksword135 (author)2009-09-28

Dude the barrel doesn't fit in the walls!

lioneatr (author)darksword1352009-09-30

that happened to me too

Jango2000 (author)2009-09-24

How far does it shoot?

poserboy123 (author)2009-09-19

try building it not so cool then

Kinetic (author)2009-09-18

Awesome job getting the mag to fit in horizontally. Range could be better but i,m sure some mods could fix that. 4.5*

poserboy123 (author)2009-09-17

that doesnt even go togather

DJ Radio (author)2009-07-20

pretty cool, looks almost like the real gun. 5*

dude10 (author)DJ Radio2009-08-19

DJ do you like leave a comment on every page. its not like your the expert at knex

He's better then most.

Millawi Legend (author)dude102009-09-15

He's better than you.

DJ Radio (author)dude102009-08-19

You do realize that this goes deeper than you think right?

smattman22 (author)2009-07-27

devon34 (author)smattman222009-09-01
