Introduction: Knex Barret 50 Cal.

Picture of Knex Barret 50 Cal.

Well, I've made the instructions sooner that I hoped for, so here you are! If the instructions aren't clear or I messed up the pictures or whatever, please let this know me, I'll fix it for you.

About the gun: As I said, CoD players will know it, and I start building right after i saw it for the first time, because it's such a fun gun to make on your own. When I started, I discovered it's a complex gun to design and not easy to built at all. The barrel and the stock mainly, the final product of the stock is filmsy, you can fill it up. I personally don't do that, I hate heavy stocks.
I've chosen for a 4-layer barrel, so the bullet has enough space.
Now, some good and bad stuff about the gun:
Good stuff:
- Looks good
- High capacity magazine
- Real trigger
- You can wear it, it isn't heavy at all
- 4 layer barrel

Bad stuff:
- the muzzle break is too big
- non-removable magazine
- sometimes the bullet get blocked in the barrel, at the orange connectors
- the pin guide sucks + the trigger block isn't placed that much back. (Far enough in MINE opnion:))

(All these 'bad stuffs' can be removed, for the barrel-problem you can use sharpened rods, like I always do.)

Now, let's get building!
Again, if you've problems, please tell me.

Oh yeah, if you've made this gun, it would be pretty cool if you post in picture so I can add it in the intro. Just PM or comment me.

Step 1: The Stock.

The stock of the gun!

The top part is filmsy, you can add stuff in there, it's all what you prefer.
I'm really sorry, the instructables at this step aren't really clear :S
You don't have to put all the black/green and white/silver rods in it, this makes it too massive and your never can take it apart :D

Step 2: Handle, Trigger and Trigger Guard.

Maybe the 7-way connectors are really annoying when you're holding it, but I get used to it.

Step 3: Barrel, Magazine, Ram Rod (guide) and Connecting the Stock. Yeah That's a Long Step Name, Isn't It?

Step 4: Front Barrel, Muzzle Break and Bipod.

Sorry, I was too lazy to take the front barrel apart. Just look good, I can't imagine it's too hard.

If you gonna connect the barrels, remove the 4 connectors as show (the yellow boxes), connect them if you've connected everything

Step 5: Scope.

If you like this scope I'll post clearer pictures but it sucks :P
Make your own if you want, but anyway, here are some pics:

Step 6: Finishing Touches.

Time to show you how to put the rubber bands, some tips etcetera.

Great job! You've built the Barret 50 cal.!
Have fun!

Some things you can change.

Is there a Way to make the Stock really firm??

FireFighter112 (author)2015-03-15

I cannot, for the life of me, find out how the trigger/fire meganism works. it's confusing O.0

zypher3.14 (author)2012-05-30

WHY IS EVERYONE ALWAYS BUILDING/BUYING/TALKING ABOUT GUNS FROM CALL OF FLIPPING DUTY?!?! (no offense though, it kinda gets on my nerves) Nice gun btw. ;)

mahmel (author)zypher3.142012-05-31

cod is the only fps with bf3 I like, and those guns are the only inspiration I get of guns. here in my country there are no gun shops etc so idk..

mahmel (author)2012-04-06

Question for all the people who have built this gun:
Has anyone (tried to) modified it so it shoots better?

dr. richtofen (author)mahmel2012-04-10

Hoeveel gele elementen heeft hij nodig? Ik zal eens kijken of ik hem dan kan bouwen en verbeteren

mahmel (author)dr. richtofen2012-04-13

pakweg 110

dr. richtofen (author)mahmel2012-04-13

Ok, bedankt. Voor die loop en zo, heb dan genoeg aan 40 witte? (ik kan er eventueel altijd vervangen door blauwe, maar daar zitten van die kleine ''uitkepingen'' in, wat nadelig kan zijn tijdens het schieten)

mahmel (author)dr. richtofen2012-04-13

gebruik voor de loop na het magazijn blauwe, daarvoor witte en dat zijn er iets van 30

dr. richtofen (author)mahmel2012-04-13

Ok, bedankt

seany28 (author)2012-04-03

rheath2 (author)2012-02-07


rheath2 (author)2012-02-05

Mahmel, I am going to use your gun to make the M98B!!!!!

mahmel (author)rheath22012-02-06

Yes, it looks a lot like at. Good luck with the stock, it looks pretty hard to make.
However I've done this already a lot: I must warn you, it does NOT shoot well.

rheath2 (author)2012-02-05

HOLY ****!

Orangepanda (author)2011-12-23

Puddock (author)2011-12-04

This is a beast!

PotatoCoffee (author)2011-12-03

Preet cool! Please take a look at my gun! =)

gassybeans (author)2011-11-20

Man, lijkt het erop dat iedereen op deze pagina is het spreken in het Nederlands! LOL

mahmel (author)gassybeans2011-11-22

haha ja idd er zijn veel nederlanders op deze site.

gassybeans (author)mahmel2011-11-22

Ik ben Amerikaan, maar ik spreek Nederlands, Duits en Russisch

gassybeans (author)gassybeans2011-11-23

gebruik je google translate om te spreken in het engels?

mahmel (author)gassybeans2011-11-26

nee, ik kan redelijk engels spreken. Maak af en toe wat fouten en grammatica en zo maar ik gebruik geen translate. Russisch lijkt me trouwens vet moeilijk om te leren

gassybeans (author)mahmel2011-11-27

Oh! Nou geloof het of niet, russisch is eigenlijk niet zo moeilijk! EN IT "S NIET FAT!

mahmel (author)gassybeans2011-11-28


gassybeans (author)2011-11-20

NICE! doesn't shoot far tho!

33devon (author)2011-10-26

what is the length of the gun and can u pls give a parts list pls cause i dont wanna make the gun and than realize i dont have anough parts :P

mahmel (author)33devon2011-10-27

Yeah that would be a shame.. Perhaps, if I remake it, I'll post a part list too.

33devon (author)mahmel2011-10-28

ok but i finaly build it but the barrel is kinda like it not stay right ir accualy bends can i fix that

mahmel (author)33devon2011-10-29

It shouldn't bend.. strange, imo it was very strong. Uhm were does it bend?

33devon (author)mahmel2011-10-30

not like it bends vertical but it bends horizontal and the stock bends vertical

mahmel (author)33devon2011-10-31

Uhm did you at the metallic connectors? And I've no idea for the stock, at never bend with mine

33devon (author)mahmel2011-11-05

i did every thing in what u posted but it bends when i put it on ground

33devon (author)mahmel2011-10-30

the front barrel bends and twists (1 tip if u make the front barrel 5 layers to and accualy dont add the red rods at the barrel just add orange conectors it works better for the bullet BTW: does a blue or a white rod shoot futher than a yellow rod)

dr. richtofen (author)33devon2011-10-31

yellow shoots further than blue/white

33devon (author)dr. richtofen2011-11-01

i think white shoots futher cause its lighter

dr. richtofen (author)33devon2011-11-01

yes, but they get more effected by the wind because they're ligter. So they start spinning around a lot, and loose speed way faster then yellows

33devon (author)2011-10-27

i think if left u should put the charging handle on the left side look like im right handed and on my cardboard sniper my charging handle is right to :)

33devon (author)2011-10-26

did u used a pencil sharperner to make the yellow rods that pointy cause i always use a knife

mahmel (author)33devon2011-10-27

You can use both

knexinventer (author)2011-09-16

i cannot connect the barrel any help?

mahmel (author)knexinventer2011-09-17

The front barrel is 6 layers, the main barrel 5. Connect them and than the ends of the main barrel will slightly go wider. Ad if it don't work explain it more, I don't really know what you mean

maltodextrin (author)mahmel2011-10-26

ha i noticed that too i was like "what?" then i got it and it works but when i fire it the yellow rod comes out the bottom where there is no red rods right after it leaves the magazine. is it because i dont have a powerful enough rubber band?
