Introduction: K'NEX Halo 3 Dual SMGs and Battle Rifle

Picture of K'NEX Halo 3 Dual SMGs and Battle Rifle

Knexfan won't stop bugging me about this so I'm posting this as a slideshow (just kidding...). All of this is copied directly from this page.

Dual M7 Caseless SMGs

I made another SMG and a Battle Rifle! The SMGs are almost exactly alike, except when I made the second one I noticed some problems and made a few small changes. Also, I didn't have enough of those swingy pieces I used for the forestock joint, so I used ball and joint pieces, which worked great.

Here is the description from the page I made when I made the first one.

This is a K'NEX model (just a model, not a gun) of the M7 Caseless Submachine Gun from Halo, better known as the SMG. It has twin notch sights, rear and fore stock, and a solid barrel. The stock is extended, the way I made it, but I'm thinking about making it collapsible. It should be fairly easy to put in a firing mechanism, but I don't plan on doing that right now. I don't think I'm gonna post instructions because I would have to take it apart. If anyone can dissect it in their minds, go ahead and make an Instructable, but make it a collaboration with me.

BR55HB SR - BR: Battle Rifle - HB: Heavy Barrel - SR: Sniper Rifle

Differences between BR55HB SR (Halo 3) and BR55 (Halo 2)
- Longer barrel
- Trigger guard

I based my model off the BR55HB SR, which is the actual name for the Battle Rifle in Halo 3, so it includes all the changes. It has the elevated rail, which has a scope on it. You might notice at the end of the barrel in the picture of the actual gun, the barrel looks expanded at the end. I did this too. The inside of the model is almost completely hollow, so it would be easy to convert into a gun. The barrel at the end would be hard though. The whole thing is very solid, even though it's hollow. It's also very easy to make, unlike the SMG.

Aeshir (author)2000smartkid2011-05-06

none of these do.

2000smartkid (author)2011-05-06

please respond

bighead5454 (author)2010-05-16

i never knew how chief loaded the SMG i thought he just shoved the mag into the side of the gun

DJ Radio (author)bighead54542010-10-07

He does.

ymliman901 (author)2010-07-15

have you watched the video my smg's on youtube?

Aeshir (author)ymliman9012010-07-15

Nope, you'll have to link me.

joshualater (author)2010-02-23

 can i get some more pics of the smg? i might be able to build and post!

Aeshir (author)joshualater2010-02-23

Sorry, I disassembled them a long time ago :(

Seleziona (author)2009-10-23

cool, 3*

Spycrab (author)2009-10-03

sick! awesome! amazing! cool! :D i can't build with k'nex XP

koenykoen (author)2009-08-05

omg thats realistic

joshualater (author)2009-04-25

i modded your br into halo 2 form (i needed pieces) but with a close up on where your barrel attaches i could make an SMG and post

SonicX 22 (author)2009-04-16

this would be cool if it could shoot but its realy cool 3.5*

joshualater (author)2009-03-26

i really love your battle rifle (i used up most of my pieces on a SMG,plasma rifle,plasma pistol,and energy sword) since it doesn't use a lot of pieces

Oblivitus (author)2008-08-03

They don't fire. :(

Aeshir (author)Oblivitus2008-08-03

Yeah, because K'NEX guns don't work, and they were made purely for aesthetic purposes in the first place. You could try making firing ones though.

Oblivitus (author)Aeshir2008-08-03

What? 99% of the k'nex guns on this site fire something. In fact, I want to make a SRv.1 to play airsoft with.

Aeshir (author)Oblivitus2008-08-03

I've made many airsoft guns, and even made up my own designs, and not one of them fired over about five feet. And I made them to exact specifications. What's a SRv.1?

Oblivitus (author)Aeshir2008-08-03

You must be new to k'nex gunning. The SRv.1 is a k'nex gun on this site made by killerk that can shoot accurately up to 75 feet. It is supposed to be able to get a piece to go up to 300 feet. Look it up.

Vynash (author)Oblivitus2008-09-08

It's SR-v1 lol not SRv-1

Oblivitus (author)Vynash2008-09-08

Toe-may-toe, toe-mah-toe, red advacado; there all the same, lol.

Vynash (author)Oblivitus2008-09-08


Oblivitus (author)Vynash2008-09-08

Tomato has two pronunciations, there is a saying about it, so I added red advocado to be stupid and funny because it's no the same as the first two. Me having to explain that just killed the joke...

Vynash (author)Oblivitus2008-09-08

Oh, I get it.

FrOnTLiNe (author)Vynash2008-12-04

At first i read Oblivitus's comment and i was like toe may toe? WHAT?!? And then i realized...

Vynash (author)FrOnTLiNe2008-12-04


Aeshir (author)Oblivitus2008-08-03

No, I've been making K'NEX guns for a long time, since 2006. I haven't made one since this gun though. I don't remember any of the names of the guns on this site. They all work the same anyway. I've tried ones that say they shoot a hundred feet, and they barely shoot at all. They're either too weak or there's too much friction in the barrel.

Oblivitus (author)Aeshir2008-08-03

Killerk's gun is different, it is a powerful slingshot. LOOK IT UP!

wow its weird

Bartboy (author)Aeshir2008-09-12


Aeshir (author)Bartboy2008-09-12

Yeah, I know. I can't figure it out.

Aeshir (author)2008-08-29

Ok, now you're just confusing me.

FrOnTLiNe (author)Aeshir2008-12-04

WOW people really don't like DarthVader. Hey Stewie is DarthVader in that one Family Guy, Its Like Blue Harvest or something I forget.

Scotish (author)2008-10-02

Why don't you just say: It took me 5 minutes to scroll down the list...

Aeshir (author)2008-09-13

I've made a bunch of K'NEX guns before, they just don't work. My pieces might be bent or something, I've had most of them since about 2000. Could you delete that? I know how to use search. I don't need a huge comment clogging up this page.

Aeshir (author)2008-08-28

Seriously! It's the right size!

Aeshir (author)2008-08-27

Yeah, it is, believe me.

Aeshir (author)2008-08-27

No, it's the right size. Any smaller and it would be too small for your hand. The gun isn't life size anyway.

bannana inventor (author)2008-07-15

Make them shoot and then post.

Aeshir (author)bannana inventor2008-07-15

No. Read below comments for more info.

Everybody stop telling me to make them shoot.

kylem35 (author)2008-06-13

nice i liked the br i have a halo 3 assault rifle fires rubberbands tho... wish i could post but i dont have a camera lol

civiso (author)2008-06-11

but do they shoot?

Aeshir (author)civiso2008-06-11

No. I've made many K'NEX guns before, and none of them have shot over five feet. I've made them exactly as the instructions say, too, and even made my own, and they still do not work.

TheDunkis (author)2008-05-27

Nice job. One of my next projects is making an actual good looking SMG that works. The only thing that stopped me from before is I couldn't figure out how to get a magazine on there. I honestly havn't played much halo (no 360 :( ) but on the real gun doesn't it load on the side in p90 fashion? (except on the side obviously) This would be hard for me to replicate so I was also wondering would you guys prefered I made a handle loading or forgrip loading magazine. The former gives better accuracy while the latter gives better power.

TheEliminatorX (author)TheDunkis2008-05-29

lol the dunkis, i think ive made one of the best smg's there are on the website, it is an mp5 with a fully working curved mag and great power accuracy and looks

TheDunkis (author)TheEliminatorX2008-05-29

OK good job. Some closer pictures would have been nice.

Reiben (author)TheDunkis2008-06-07

might be making this from unreal 3

Aeshir (author)TheDunkis2008-05-27

Yeah, it loads on the side. I don't think a handle loading mag would work, if you have the trigger mechanism in there too there wouldn't be any room. You could even switch them around and put the trigger in the forestock and the magazine in the handle. You could put it in the butt stock also, there's a lot of room in there, just the basic frame there actually.

Aeshir (author)Aeshir2008-05-27

There's a little problem though. You could probably find a solution to this, but there's barely any vertical space in the frame between the handle, fore and butt stocks. I don't know if you could get any kind of barrel in the existing space.
