K'NEX Halo 3 Dual SMGs and Battle Rifle

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.

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.

Hey can i post instructions for the SMG (maybe the Battle Rifle if I make it)?
Aeshir (author)  bighead54547 years ago
Yeah, sure. That'd be great :D
ya i cant make it 24 inches (that is about as long as my arm) because it would be a gun for a giant or something but it is at about 16 inches
ok thanks but it might not be anytime soon because i need to mod it just a little more because i want to make it as close to 24 inches (about its in-game length) at possible and MAYBE make the stock collapsible (probably not)
