Introduction: K'nex Bolt Action Bullpup F2000 [Edit]

Picture of K'nex Bolt Action Bullpup F2000 [Edit]

Ok, a few people have known I was working on this for a while now, but here it is.  It is an FN F2000 replica, as the F2000 has been one of my favourite assault rifles for a while now, (not due to CoD before anyone accuses me of that) and I decided it would be an interesting challenge to see if I could make a bullpup weapon a viable choice for power as well as looking good. 

The bolt pin pushes the blue rod from the removable magazine (with the mag release button in the correct place) about 2 inches forwards from the front of the mag and up a ramp into a holding piece that stops it sliding around in the 'chamber'.  This extra distance maximises the distance the firing pin travels and so increases power.  The true trigger is attached to a block trigger above the magazine well' just behind the rear iron sight.

The weapon can shoot, hit a wall 10 feet away, and bounce the rod back to hit me in the face, with one #64 band. 

Unfortunately, I could not attach a fake barrel to the front in a way that wouldn't block the path of the rod and look good; the rifle simply looks better without one in the wrong place.  I have also redesigned the optic since these photos to make the front more sloped and therefore look more like the real deal.

Some credit goes to Ironman69 for the internal mag pusher.  Everything else was made by me; if any other parts resemble anyone else's design, that is purely coincidental. 

Plase rate, comment, and subscribe.

EDIT:  I made some mods.  No pics seeing as I'll be posting it soon enough anyway, but I changed the bolt and pin raiil slightly so it works more smoothly and the pin doesn't stick out of the top any more.  I also changed the trigger to a design that can hold more power.  I did some range testing with 3 #64s and it can fire about 50 feet flat with a blue rod.

Thanks for all the ratings and comments guys; this is now the highest rated K'nex gun on the site at 4.24*.

Incredible gun ! It's fantastic ! That's one of the best gun ( after the Z3 of Oblivitius ) on Instructables ! I love it ( the gun , of course , ;)

DeathSkull (author)2012-03-19

My favorite gun is the FN2000. I use it a lot on MW2. Obviously you did a fantastic job with the new bull pup mechanism and the trigger.

PiTBuLL892 (author)2010-05-20

awesome i MIGHT build when instructions come up but it all looks a little bit big than a normal f2000

knexguy (author)PiTBuLL8922010-05-20

Not really.  I assume all you know about the weapon is from MW2?

Thanks either way, I posted instructions just before you posted that comment.

PiTBuLL892 (author)knexguy2010-05-22

nope i know too much about any gun really..
the fn f2000 is created by fn herstal basted in belgium, they are also well known for the p90 and the scar-l and scar-h.
it fires the 556mm nato round used in most modern assault rifles (exept for ak-47 that fires the larger 7.62mm round)
it is a bullpup weapon meaning it can have a long barrel in a smaller shell giving it more power and accuracy in a lighter and smaller gun.
it is adopted by some military forces around the world.
that enough facts for ya??

wabawaba (author)PiTBuLL8922011-06-28

also the fn f2000 also has the forward ejection system, also uses the stanag mag as the standard for the fn2000

knexp90 (author)PiTBuLL8922011-02-10

well, there is the posibility that you just looked up those facts, but those are all true. you should have stated that the mag for bullpups is way farther back, that way it can have the longer barrel length.

knexp90 (author)PiTBuLL8922010-11-09

jeez, you sound like that guy on future weapons. what was his name again?

oh, PiTBuLL892. Thats right

RedStark (author)knexp902011-01-23

Mack his name is
:) i watch it all of the time.

sandmman (author)PiTBuLL8922010-12-11


knexguy (author)PiTBuLL8922010-05-23

They are known for more than the P90 and the SCAR series of weapons.  What about the Minimi (M249) series?  Or the FAL, or their huge range of vehicle based armaments?

ryry2011 (author)2011-02-12

Why not read the comments below!? I HAVE posted and 'ible. Go to my page to get to it.

codemaster2590 (author)2010-06-14

Any timeline of when you plan on posting instructions? or maybe could you atleast take a pick of one side off to see the insides?

knexguy (author)codemaster25902010-06-22

'Ible has been up for around a month, lol. They're not great, mind you.

yerjoking (author)2010-05-14

I can has credit seeing as I made first bolt action bullpup? ^,^

Millawi Legend (author)yerjoking2010-05-14

Where? I don't think you did!

yerjoking (author)Millawi Legend2010-05-27

Actually, I think you'll find I did. Zak and the other KI'ers can confirm it, as can Jamalam, Dunkis, Loosewire and a few others possibly. It wasn't the best but it was the first. Just because it isn't posted doesn't mean it doesn't exist.

Millawi Legend (author)yerjoking2010-06-11

But, everyone is going to find it very hard to belive you acctually did.

yerjoking (author)Millawi Legend2010-06-14

But, if you read my reply, I stated that numerous people can confirm it.

knexguy (author)yerjoking2010-05-15

I hope that's a joke. 

yerjoking (author)knexguy2010-05-27

Yeah it's a joke, but I did make the first, lol.

knexguy (author)yerjoking2010-05-28

I don't remember seeing it ever.

yerjoking (author)knexguy2010-06-04

Yeah, I only spoke of it like 4 times on here, but nobody seems to pay attention. Either way, I'd say yours was alot better than mine anyway. Mine shot like 10 feet if lucky.

matsermetsuiker (author)2010-05-27

best replica ever~!!

FlutterTree (author)2010-05-24

Look forward to building, and the gun is at 4.31*'s. :P

knexguy (author)FlutterTree2010-05-25

It was posted nearly a week ago...

Have fun building, I'll be adding the mag to the 'ible tomorrow.

FlutterTree (author)knexguy2010-05-25


knexguy (author)2010-05-19

Ok, I've finally finished taking pictures, (except the mag, but I'll do that while the rest are uploading)  so you can all expect the 'ible by tomorrow at the very latest, but probably just a few hours from now.

shmi117 (author)knexguy2010-05-19

Hmph... Still not up.. oh well, I guess Ill have to wait a little longer...

knexguy (author)shmi1172010-05-20

It's here.

shmi117 (author)knexguy2010-05-19

Wow!!! Still not up! Will it show up under recent? Or where?

knexguy (author)shmi1172010-05-20

You have to bear in mind time differences, I've been asleep all the time between your last comment and this one...

It will be up around lunchtime today (GMT).

Brammetje (author)2010-05-19

Is the ammo a dark gray con and a orange con because i thought so?

knexguy (author)Brammetje2010-05-20

No, it's a blue rod length rod.  Connector ammo wouldn't work with the mech.

KnexFreek (author)2010-05-14

 Wonderful work. Love it.

TheChemiker (author)KnexFreek2010-05-14

Your back!

Seleziona (author)TheChemiker2010-05-18

no, it's still oblivitus :P

TheChemiker (author)Seleziona2010-05-18

Then what is the point of using knexfreek's account?  What is the point of allowing someone with a perfectly good acount to use another account?  Knexfreek should have just dissappeared, like ksc did.  And anyway, I should have expected something like:

OMG!!!111!!  AMAZING!!!11!1  POSTNOW!!!111 I LOVE IT!!!!!1  AWESOME!!111

Or something like that.  He has a caps lock problem.

Seleziona (author)TheChemiker2010-05-18

 LOL, and he is coming back, he is just trusting oblivitus with his account for a few months. He IS coming back.

TheChemiker (author)Seleziona2010-05-18

I know he is coming back, but what is the point of giving you account away for a while?

Seleziona (author)TheChemiker2010-05-19

I dunno, to answer all of the comments he gets?

TheChemiker (author)Seleziona2010-05-19

Oblivitus has posted 3 or 4 comments so far with his account........

knexguy (author)KnexFreek2010-05-19

Thanks ;)

shmi117 (author)2010-05-18

Is the mag easily removable? And does it just lock in place? That would be sweet if it does!

knexguy (author)shmi1172010-05-19

Yes, you just press the button and the mag falls out.

shmi117 (author)2010-05-18

PLEASE JUST POST IT NOW!!! I literally can't wait... IT IS KILLING ME!
