Picture of Knex Halo 2/4 Battle Rifle replica.
knex halo BR 025.JPG
Update 12/16/12: In light of Halo 4's new battle rifle, which has angles and curves this replica doesn't match, I am here to make a note that this was supposed to be based off of halo 2's BR.  Due to a recent comment, I have updated the title as well as add this note to reflect the new game's release.

Behold, possibly the best knex Halo Battle Rifle replica ever made in terms of looks.

Unfortunately, it has a few downsides. The mech doesn't work first of all. I have other things I want to do, I've been working on this for over a month now, and I don't want this project to go to pot because it looks so damn good. So here is what I am going to do:

I will post instructions for the gun "As is". If anyone wants to fix it and make it work, be my guest. You can make it single shot, or mag fed, whatever, as long as it works without butchering the look. If anyone does fix it, they should make a video of it shooting, and send me the raw file over Skype (My skype name is dj_jazzy_jeff1, if you aren't already in my contacts, say that you fixed my BR in the introduction message)

If I like your fix, you will then be a collaborator on this instructable, changing all the steps so they build your version. I will give credit to you for fixing the gun, but I must maintain the majority for making the gun look like it does. You will receive a patch and a subscription if you help me.

In the meantime, I'm touting this as a non-firing model with parts of a mechanism in it. Don't call me hypocritical for asking other people to make their replicas shoot, because believe me, I made the effort. Nobody who I have asked didn't even bothered trying.

NOTE: Building your improved version in metallics is optional.

Here's a video of it:

I think you could make the instructions more detailed. If you don't know what I mean, then go to Seleziona's channel on this website and look at a few of his instructables. They are very detailed and easy to understand.

Back in the days of Halo 3, this looked ok. But it looks a lot like the new BR from Halo 4, so nice job planning ahead :P

I have updated the title to reflect this.

Never ealised how great it is. I've made it, it's awesome!
Nice job! It looks really realistic!

I love halo guns, and this is a perfect knex version of a battle rifle. I would love to build a knex DMR, as it is my favorite halo weapon next to the spiker.
DJ Radio (author)  Puddock3 years ago
WIth enough mods this could become a DMR. Honestly though I liked the BR better than the DMR. BR spread was better than the bloom the DMR has.
What sort of range did the firing version of this gun get?
with mine i got atleast 30 feet but i never actualy tested it outside so im unsure
Yup. Well mine could get 100ft with a string of 3 #64 bands.
i used more then that on it
Thats good to know.
DJ Radio (author)  beanieostrich3 years ago
Dunno. Never really asked.
Ok. I had intentions on making this gun; the only thing I am not too sure about is my piece amount. If I ever get around to building; I will tell you what range it gets.
I am currently making the gun now. And modding it as I go.
I know I am triple-posting but your gun gets 105 ft range.
DJ Radio (author)  beanieostrich3 years ago
Here is my version. I know its been butchered a little but yea.
DJ Radio (author)  beanieostrich3 years ago
What is this I don't even...
Its just my version of your gun. I knew you wouldnt like it.
DJ Radio (author)  beanieostrich3 years ago
I like it but I don't know why you messed with the front end.
Doesn't so much look like a battle rifle.
I know, thats why I said it was butchered up. I just felt like modding it to my liking.

I have to admit, that's sexy.
DJ Radio (author)  apples!!!!!4 years ago
You know, I think it's interesting how you and I each built a Halo weapon in the exact opposite manner. You built a perfect replica and failed with the mech, I built a working mech and failed with the looks. I think I'll work on this this soon because it is seriously one of my favorite builds.
DJ Radio (author)  apples!!!!!4 years ago
You built a halo replica? And thanks! FYI, the original mech was taken off of a gun on Jollex's Youtube channel. That's just so you have something else to use as a reference.
It's not a replica by any means, but I added it to the photo 'ible I posted recently. It's more of a concept that I tried to make look like a Brute Shot since no one else has made one, lol. And ah, I might look into that...I'd probably try to start fresh, though.
DJ Radio (author)  apples!!!!!4 years ago
Oh I thought you might try and make this and make the mech work. Starting fresh is fine though.
Ah, I could try this first and see where I get, but I tend to do poorly when trying to work off of other peoples' ideas.
DJ Radio (author)  apples!!!!!4 years ago
Ah, I guess it varies from person to person then.
It does; that's the wonderful thing about having a community. The problem is that I tend to sacrifice looks to make mechs work(like with my brute shot). I dunno, I'll try my hardest but it seems that even though I built a cannon with a mag, it's dissatisfactory lol.
DJ Radio (author)  apples!!!!!4 years ago
That's alright when it comes to making a performance gun, but in replica land, making it look good is what counts. Some people say that if a gun has a good design and is nice and neat and clean it will also look good in most cases.
Meh. I just say that I based it off of a Brute Shot(because I did lol) in the 'ible I just finished. But whatever, it's still at least a try when no one else has something similar to it lol. I still love yours >.>
DJ Radio (author)  apples!!!!!4 years ago
It's not bad lol.
That's because no one knows what a brute shot is supposed to look like off the top of their head :P
DJ Radio (author)  apples!!!!!4 years ago
Use a reference pic?
That would show all the angles and proportions I got wrong lol, I think I'll stray from that...
DJ Radio (author)  apples!!!!!4 years ago
That's kind of the idea here.
Nooo I no make it look bad! It doesn't even matter lol, like five people even know abot that thing anyways.
dsman1952764 years ago
Ah, Love the look, it's a shame the the mech doesn't work, but none the less, heres my review:

First of all, the looks are GREAT. Looking at that picture, you hit the nail on the head. It also looks really sturdy, which is always a plus. I like how you pretty much matched every curve that the gun in the picture has. You even went as far as to extend the top of the stock just a bit to match the picture. That's impressive if I do say so. 110% for looks.

The only thing I didn't particularly like about the looks is the scope. It looks a bit out of place if you ask me. I'd love to see a redesigned scope with bendy rods, and some more aesthetic changes. You're got a amazingly designed gun here, no need to ruin that by shoving a average scope on it, I'm sure you're more then capable of making a good looking one ;-)

Now the mech, I had a idea for that actually, ever think of shoving a DD-27 barrel on the end instead? I do think it'd kill the look(You're call though). And if you do, you could put the Firing-Pin right inside the body, along with the trigger(Extending the trigger on the front to connect to the trigger by the handle shouldn't be to hard). You could either extend the firing pin, or just tie string to pull it back with, either would work. I don't have the parts right now to test this out, but I think it'd work well.

DJ Radio (author)  dsman1952764 years ago
The mech didn't really work because it was based off of concept technology. The gun I borrowed it from just so happened to have the top of the stock extended like on the real battle rifle. Thanks for that though.

Also I was running rather low on parts by the time I built the scope, so I had to whip this one up in about 5 minutes. No choice there.

That sounds like a look-ruiner on one hand, but if designed right it wouldn't affect much. Maybe it could be your next project to help you get back in the game?
that gun is cool

KnexFreek4 years ago
Well i dont play any video games.. but based on the picture of the gun from the game, it looks Exactly like it!! it may not shoot but it sure as hell looks like an accurate replica. Very well done 5*
DJ Radio (author)  KnexFreek4 years ago
Lol thanks. I worked really hard on it, about a month. Mind trying to see if you can get it to shoot?
I could get this shooting, BUT i have no dam Knex!!!! LOL
My birthday is this weekend and im getting some :]
DJ Radio (author)  KnexFreek4 years ago
I'm gonna get more knex too. And Happy would-be birthday. Mine was in February lol.
Haha thanks. how much do you have?
 Ive got around 0..

WAIT! maybe theres one under the couch cushion!!!  YES!!

DJ Radio (author)  KnexFreek4 years ago
ROFL LOLOLOLOLOLOL I didn't get much more knex since you left but I'm about to get 10 pounds worth from one of my friends.
Randomguy654 years ago
That's one hell of an accurate replica.
DJ Radio (author)  Randomguy654 years ago
Thanks! Although IMO it's terribly underrated. This is probably the absolute best Halo BR replicas out there (If you don't believe me look at the others) and it only has 1000 views and a 4.5 rating? If you look on youtube you can find 2 rather crappy replicas that both have over 9000 views.
The only reason I can can see why people rated down is because it doesn't shoot. Some @$$holes may not know the term REPLICA.
DJ Radio (author)  Randomguy654 years ago
I've seen non-firing replicas get to 4.85 before, in fact this one was at 4.85 one time. Pretty much EVERY single thing I posted got downrated about 3 or 4 times at the exact same time and this got affected the worst since it was newer.

how many white connectors and how many blue 3d connectors do you need
DJ Radio (author)  AUG-5OM34 years ago
Quite a bit. I never really counted though. You will need way more yellow connectors though.

Nice, glad to see at least someone still uses K'nex. I kind of miss it....
DJ Radio (author)  Bartboy4 years ago
It's not too hard to sit down, pick it back up, and snap it back together. Unless you sold it.
Well it is, when you're in high school taking courses two years ahead of you that just pile on useless homework where you don't learn anything.... Physics is insane how easy it is compared to how much work we have.
DJ Radio (author)  Bartboy4 years ago
Your school must fail. The homework I get at my school isn't exactly "useless", it helps me remember what I may have forgotten when I was dozing off during lecture.
Also, I don't have any trouble remembering the stuff, but others do. So it's only really useless for me.
DJ Radio (author)  Bartboy4 years ago
Wowwwww. I hate how not doing it hurts your grade.
One weekend I had 60 questions from my physics textbook. SImple math, all V=D/T. Every answer needed to show all work, and be in full sentence form.
Just physics.
And insane stuff with music. Playing stuff in 19/6, 9/8 and a lot of 7/4.

Quite nice looking.. If someone made a needler that just looked cool it'd be cool.

Lol the needler is probably the trickiest to make out of knex.
Exactly. =p

Trololo ftw :D Haha nice gun btw, it's a bit too massive
DJ Radio (author)  mahmel4 years ago
It's around the size of the actual BR. It's a bit too big for me but it looks like it would fit snugly in Master Chief's hands.
mahmel DJ Radio4 years ago
Hmm I meant it's the top rail, for example, thats too fat. And I don't like the that you say prob best halo gun in terms of looks:S
DJ Radio (author)  mahmel4 years ago
You don't like that? Take a look at the others. Look at theirs and compare to mine.
mahmel DJ Radio4 years ago
Ooh yeah I didn't mean it isn't the best halo 2 battle rifle knex replica (I know the others sucks). But I think you should be a bit less.. sure of yourself. And I don't think you ARE that but Ithink maybe some people will think you are.
Oh yeah I thaught you mean the best replica of ALL halo guns here.
(sorry for my amazing english:P)
DJ Radio (author)  mahmel4 years ago
I did research. I looked up the other BR's and they were all just skeletons, except dutchwarlord's, but the angles on his were off. Speaking of which, why is his rated higher than mine when mine is a more accurate version than his?

Replicas of the other halo guns aren't too great anyways aside from DRADIS's plasma rifle and s0lekill3r's Halo SMG. Those 2 were pretty good.
mahmel DJ Radio4 years ago
hmmm okay... But if you compare, you stop building it better when you reached the best replica, understand? Please always be hard to yourself and always say it can be better.. Because some things just don't look that good, (in my opinion! (But hey, who am I, right?)). And I don't say it's bad....
DJ Radio (author)  mahmel4 years ago
I agree there's some improvements that can be done with my gun, but I don't have the time to do it, so I place the burden on the community to make the best so far, even better.
mahmel DJ Radio4 years ago
It's okay! PS yeah I understand it, I don't have plenty of time too.

Hey DJ, I made it, and made a mechanism. It isn't great, but it works! I'll post it when I have the time (FINALS ARE KILLING ME!!!).
id like to see a picture of the gun and the fireing mech area

Send me a vid first over skype.
Ok, will do. It is very VERY suckish. Just saying. It fires though.

omfg this iz epic!!! 5.0
Ammo? What is it, blue rod or orange+ green+ grey?
DJ Radio (author)  TheFoofinator4 years ago
blue rod but you can make it whatever you want.
wait, so is it like a slingshot? You just pull back the rubber band on the ratchet and when you pull the trigger it releases the rubber band and it slings the bullet out through the front, right?
Thanks- might have a crack at concept I've thought of.
DJ Radio (author)  TheFoofinator4 years ago
As long as it works and you're willing to make a video, and change the ible to build it.
I've made the slingshot mech work, but in another gun. I'll post both my slingshot guns, demonstrating Jollex's mech and Knexfreak's mech. That concept will come later- I don't have the parts. I will ask my cousin to make it.
DJ Radio (author)  TheFoofinator4 years ago
You don't have enough to build this gun? I just barely had enough and I used up all my green rods.
mines working!!!!!! yay im still modding it to make it the best
DJ Radio (author)  knexsuperbuilderfreak4 years ago
As long as you use good grammar on the ible.
1 comment!!!!!!!!!!! and ausome gun to i wwill make this weekend hopefually
DJ Radio (author)  knexsuperbuilderfreak4 years ago
Please fix it and build it in metallics if you can.
i can make most of it in metlics just a few white connecters might be in there and what do you meak by fix it?
DJ Radio (author)  knexsuperbuilderfreak4 years ago
That's fine.
i finshed it and i have made the pin WORK but it isnt wanting to fire right so i need to re do the mech...
i have started to make it...
i see whats wrong ill make it asap but i dont under stand the "pin" at the end of the gun
DJ Radio (author)  knexsuperbuilderfreak4 years ago
That blocks the mag and keeps a round from loading into the barrel until you pull the band back. Look at Jollex's "Kong" video to understand.

Awesome!!!!! Just a question, does it shoot?
DJ Radio (author)  Raz1r Knex Bull3t4 years ago
I tried to get it to shoot but the mechanism failed me. I wanted someone to fix it.
alright, so, is there pics of the old mec?
DJ Radio (author)  Raz1r Knex Bull3t4 years ago
There is no "Old mech". It's always been what's pictured in the ible.
oh, okay.
Hmmm.... If what is wrong is the strip of orange connectors bending up, then that can be easily fixed. I can make just the mech if you want with the strenthened strip, I will do it tomorrow.
DJ Radio (author)  TheFoofinator4 years ago
Not just that. There are some issues with the pin that blocks the mag and also the part with the angled orange connectors.
Vynash4 years ago
Awesome gun!

I'm not sure I'm going to build it until someone fixes it but anyway this totally deserves a 5*s and favorite.
DJ Radio (author)  Vynash4 years ago
You could just hang it on your wall or something to show off.
Nice! (I'm guessing this is the gun with the iffy mech?)

If you're good at photography can you please give me a pic of the gun in metallics?
