Introduction: Working Knex M4 Carbine Model (not Full Scale, RBG)

Picture of Working Knex M4 Carbine Model (not Full Scale, RBG)

An M4 Carbine I made out of Knex with removable magazine. The handle, sight, stock, and barell are all interchangeable, and I'm currently working on a SOPMOD kit to go with this.

(The picture shown here is short stock, short barrel, short gearbox, short trigger guard. The ratio of measurements is closer to a colt, but with a curved magazine. The newest model Has long everything except for barrel. The reason for this is because the longer the barell the harder it is to support it's own weight. The proper measurements being implemented in Knex [14.5 inch barrel, 33.1 inches total with stock extended] would be very fragile. The current model has been dropped out of a second story window with the only damage taken being an expelled magazine. Take your pick for which one you want.

Knex Guru (author)snowbird12010-07-24

That's actually not mine, but I do own a Bushmaster which is very similar.

It's pretty cool. But, it would probably be easier to use if the stock was longer, even though it is a miniature version.

Knex Guru (author)Oblivitus2008-08-18

Thanks for the input. I'm trying to make it full size, but it gets wobbly without enough support. (Why the barrle is short.)

Oblivitus (author)Knex Guru2008-08-18

Have you seen nightfox's M4?, that might help you.

Knex Guru (author)Oblivitus2008-08-18

He's where I got my insparation from, but I wanted to build something from scratch. Want me to get a ruler, and make everything perfect, becuase I can.

Oblivitus (author)Knex Guru2008-08-18

Naw, I just eyeball stuff. Like my AK47 I finished recently.

y does it look like the stock has been melted

Oompa-Loompa (author)Oblivitus2008-08-18

Which I still want to see posted.

Oblivitus (author)Oompa-Loompa2008-08-18

:). I'm working on the instructable, bit by bit.

Oompa-Loompa (author)Oblivitus2008-08-18

LoL ok.

Trauts (author)Oblivitus2008-08-18

I just wanted to show you something that might make the mag look a bit better since I love the rest of it so much. The left side is yours, and the right side is a real ak47 mag. (sorry for it being terribly drawn). Ignor the size difference it's just the corner im showing you.

Oblivitus (author)Trauts2008-08-18

Thanks for the effort, however, I realized that but the flexible rods extend further than that so it's not as simple as it seems to modify. I would have to change the connection to the gun where the clip meets the fake breach.

Trauts (author)Oblivitus2008-08-18

Alright, i'll be waiting for you to post cause I have a 1:1 scale AK47 airsoft gun XD. But just looking at the pics it looks great.

Oblivitus (author)Trauts2008-08-18

Yeah, you told me. :)

Knex Guru (author)Oblivitus2008-08-18

If you send me instructions for the breach, i might be able to modify it. I'd need to know what kind of round it takes though.

Knex Guru (author)Trauts2008-08-18

My 74 looks like the one on the left. (I have a 20 round, semi-automatic due to regulations.) Are the 47's different?

Knex Guru (author)Oblivitus2008-08-18

I've seen that earlier today. The one thing I found wrong with it is the clip, where the green connector is at the bottom, put a yellow one instead. It would give it a less snakey look.

Oblivitus (author)Knex Guru2008-08-18

Yeah, I see what your saying but I'll keep that the same. I am working on an instructable for it and I already have a ton of pictures of it as is.

Knex Guru (author)Oblivitus2008-08-18

I'm making my M4 to scale.

carrothead23 (author)2008-11-25

Knex Guru (author)Reiben2008-08-25

Because only one person in the world can have a single idea on how to shape plastic peices together and make it look like something. -_-

hehehe i know the story how knex came to earth XD

dynno97 (author)Knex Guru2009-02-09

not if u just copy off of someone else

Knex Guru (author)dynno972009-02-11

Good thing I made the clip, handle, reciever, stock, barrel, and sights with my own design then.

knexsniper1 (author)Knex Guru2009-05-10

i like your sense of sarcasm, its amusing! 5 stars! great gun dude!

thomaswatton (author)2008-12-21

Knex Guru (author)Undermig2008-11-29

Undermig (author)Knex Guru2008-11-30

im trying to say l9ol ure funny.... were is ure canon to shoot??? its occupide by some black circle things on a rod... wow wath a Mor##

Knex Guru (author)Undermig2008-12-05

I'm a moron? You're reffering to, as far as I can tell, a barrel as a cannon. It doesn't need one because it's a RBG. If you read you might know that.

pls (author)2008-12-03

Looks small, thats what makes it awesome!

bullet-head (author)2008-09-06

benboy207 (author)2008-08-23
