this should be a model

super happy fun (author)2011-01-21

teach me how to shoot it.

ryandude101 (author)2010-04-10

i personally think this didnt work the gun felt quite floppy but i guess that becaus it is a collapsing gun and the firing was hard as the trigger kept brakeing but it didnt feel very powerful wen is firing as its wasnt very accurate, is there any way to put a cover over the barrel?

but it does look and feel nice

erikos kostarikos (author)2009-06-27

well the firing mech is simple, and its not special because it can fold.
it flods, but its not easyer to take i with you...
the instructions are good but bad pictures=(

Andrew5909 (author)2009-06-09

i seem to only have 1 problem with this carbine and that is when ever i try to fire the trigger keeps snapping apart for me and the snapping bits are the white rods. please can you repost a different trigger so that i can at least fire it without breaking my finger like a n00b. all in all the rest of the gun is great but it only has that one problem.

What makes it a carbine and not just a K'Nex gun?

!revenge! (author)2008-03-19

didnt the gun had some sort of pump on the front ??????????????

robot builder (author)!revenge!2008-04-01

yes it did y isant thare a pump??? put the pump back on!!!!!!!!

There never was a pump. This is the carbine. The one you are thinking of is his Halo "assault rifle. He removed his videos. Nothing I can do. Shown as he made it.

Mango Man (author)2008-03-16

This gun rocks! I got mine to shoot up to 50 feet with 2 rubber bands! definitely a favorite!

JTF-3 (author)2008-03-09

Wtf how does this even fire. You pull the bullet back, attach it to the blue rod, and it just stays there...

alecgates15 (author)JTF-32008-03-09

You pull back on the trigger. The piece attached to the blue rod.

hey i waz about 2 post dis gun darn it o well i hav mods 2 dis i waz gonna show 2 day but u posted lol o well

Whaleman (author)2007-10-22

Hmmm, interesting, but I have a few questions/criticisms; First, did you have tomboyRME's permission? Two, You need better lighting, and Three, A carbine is a short gun, which does not seem to describe this gun. All in all, pretty good.

alecgates15 (author)Whaleman2007-10-22

tomboyRme responded to my query near the bottom of the page. My lighting is crap because it was night, ceiling light was burning out, and I'm a crappy picture taker. Anything designed or named is his I take no credit. In the future I will make my own weaponry. Not someone elses, a mod, or a block trigger, simple, ultimate, knex gun. I apologize and would like to know if you have any pictures of your m4 before you scrapped it. I am interested in finishing it. Thanks for reading.

Whaleman (author)alecgates152007-10-22

well, I haven't scrapped it completely yet, but I need more batteries for my camera.

alecgates15 (author)Whaleman2007-10-22

Alright. Just wanted to know ahead of time. How far along did you get before deciding m24? I'll get started building with the pictures available. Anyways nice job.

Whaleman (author)alecgates152007-11-09


adamsdead (author)Whaleman2007-11-26

I thought you scrapped that.

Whaleman (author)adamsdead2007-11-26

Doesn't mean I don't still have pictures.

adamsdead (author)Whaleman2007-11-27


alecgates15 (author)Whaleman2007-11-09

Thanks I'll get straight to work.

Whaleman (author)alecgates152007-10-22

I got everything except for the charging handle and the foregrip/ barrel.

ak47 Sharpshooter (author)2007-10-25
heres my proof, titled how to make: carbine

How do you shoot it?

buterSBob29 (author)dot123212007-11-09

you pull the 2 white rods connected to the orange conector

I made this instructable back in August and forgot to publish. I published it because there are still those who have no idea how to build it.

cstrike pwner (author)2007-11-04

i like it becouse you can take the barrel and make the rest how ever you want. My friend made a sniper rifle and it hurts. Nice instructable

knexguy (author)2007-10-22

looks a bit like adamsdead's rifle; nothing new.

knexguy (author)knexguy2007-10-22

Sorry,the trigger is new.

knexguy (author)knexguy2007-10-22

And i do realise it is not yours.

iKill (author)knexguy2007-10-23

lol your completely mistaken this is nothing like adamsdeads rifle, which is so far my favorite gun on the site. its really solid and reliable with lots of power

knexguy (author)iKill2007-10-25

ok, ok

Kaiven (author)2007-10-22

i like the shape, and it's true trigger :)

flames10391 (author)2007-10-22

i just built this like 2 days ago and i still hate his trigger mechanism but i like the shape and stuff
