The M4 Carbine

This was posted on my Birthday (21st Jan) (even though it sais the 19th) :)

1.0 - Base Gun with no updates and no accessories

About my gun:

Credits to The Dunkis' for the (most excellent) magazine.

Based off of the M4 Carbine in Call of Duty 4: Modern Warfare

This is not an M4A1 Variant...



Model: M4 Carbine

Mechanism: Slide Action FPM

Range: 20-50 feet depending on Rubber Bands used… mine got 30 with one (loose/weak) #64

Magazine: The Dunkis’ (amazing) STANAG



Great looks



Stock is a little too large for my liking…

I don’t like the carrying handle…

Pieces Warning: This build may take up a lot of your pieces. It includes a large count of Y connector "Black Hands" - 25 in total. Also you'll need 8 half orange conns. Also, a black rod is recommended, but not required...

If you can, please take time building this.

I will look forward to seeing your comments.

And last but not least, please comment, rate, comment again, then subscribe :)

there ya go guys

please note that MotaBoi's M4 and mine started off as a collaboration and that is why they have the same grip idea...

This is my Desert Eagle .50 model... it probably wont be posted as a full ible...

Also sorry about the lousy instructions for the AK and M4, I got really bored making them and i thought that writing the words over and over again is pointless.. especially as you guys can easily guess what im gonna say..


knexlegend101 (author)2017-02-26

i didn't have enough pieces so i shortened the gun

knexlegend101 (author)2017-02-26

this is awsome

haloisbeast504 (author)2014-10-27

dude this... is...BEAST!!!!!!!!

2000smartkid (author)2012-10-28

post instructions for the desert eagle. I think everyone who looked at it would like to build it, including me.

2000smartkid (author)2012-09-29

Can you post instructions on how to make that Desert Eagle? It looks awesome, and if you post instructions, I can make it. Nice M4 Carbine too.

Orangepanda (author)2012-01-18

hey barrax, u r sooo cool.
er if u dont mind me asking how old are u?

This is Barrax (trust me, no-one would fake being me anyway)...

I haven't checked this website in years... I'm 16 now, but was 13 when this was posted (actually 2 days before my birthday).

Thanks to everyone else for continued interest well after I got banned, just wish I could turn those 80,000 instructable views to Youtube views.

Should I get back to building? Looks like instructables has died down since.

Also I got banned (hence the cross through line) for the following reason:

Me and DJ Radio took part in a prank that insulted another member, DJ didn't get banned though. That annoyed me.

Not sure if I want to get back to building...

~Meme~ (author)Propane Flair2012-08-15

knex obsessed (author)2011-03-02

The M4A1 is the M4 Carbine but on modern warfare 2 they give it the new sights. as an M4 Carbine is the M16 but with the fire mode set to full auto

Don't trust video games.

jdttc (author)2011-07-19

gassybeans (author)2011-07-11

DrWeird117 (author)2010-11-16

Wow, that delta ring looks really cool. Looks tough and durable, too. Great job.

knexkeiron2010 (author)2010-10-22

Who's pistol is that in the 4th pic it looks real

chopstx (author)2010-10-16


Only build this if you are just going to set in your room where it will NOT be touched. This gun is very vlimsy and breaks way too often. That is why I never should have built this because when i try to shoot it, either the stock, fore barrel, or handle snaps off.


mahmel (author)2010-10-12

From who is that pistol..
please say asap

knexrock44 (author)2010-09-16

barrax (author)slipdiddy1012010-07-11

james4 (author)barrax2010-08-07

james4 (author)barrax2010-08-07

slipdiddy101 (author)barrax2010-07-11

CuddlesMcT (author)2010-07-30

Tip: use red rods for the barrel insetad of grey. It looks way more proportional for the M4
