Decided to go back and work on the old Battle Rifle from scratch. I think I got further than my first attempt in just a couple of hours. I've taken into consideration how a CNC machine would cut this, so certain corners have been rounded to take into account of a cutter passing through. The heat shield would probably be made out of 1/16" or 1/8" sheet metal, with the vents cut on a manual milling machine and later bent to shape. The pistol grip hasn't been included with the lower receiver, I'm planning on using a M4 pistol grip (Magpul MOE grip to be specific). The shape of that area is bound to change in upcoming versions of the model. The idea for the internals will be to use a P90 or similarly low profile gearbox. Magazines used will most likely be M4 mags, due to how common they are and how easy a mag catch can be built for them, if not simply bought instead. Here's the lower receiver and part of the upper receiver so far.

It looks great so far. You have any plans of taking orders for it once you get everything set?
I've always wanted an Airsoft AR2. But a Battle Rifle is pretty cool too!
As much as I would like to sell it, there's a number of issues. 1. Cost: Buying large pieces of aluminum this size doesn't come cheap. Then having it made on a CNC machine isn't cheap either if it has to be sent out. My best hope would be for a company to buy the design and produce it. 2. Copyrights, etc: Since Bungie did create the original model there may be some sort of copyright issue involved if these were sold. That, and I'm basing this off a 2D CAD file someone else drew up.
What happened to your last project?
You mean the other bullpup I was working on? I just sort of stopped on it when I realized I made it too thin and it would be a pain in the ass to bulk it up without screwing up some of the rounded features. Plus a Battle Rifle is a little more recognizable. I'll try to maintain some of the old features I wanted in the custom bullpup, such as a rail system and ambidextrous controls.

I may try to see if a standard Ver.3 gearbox could fit in here. Update: Carry handle extruded. Still needs to be cut to shape (angled sides, detail, etc). I added a 5 inch flat on top to make the installation of a rail easier. The original drawing had it as a curved top. Also realized I have to remake the whole cheek rest, it's not centered and extends past the edges of the lower receiver. Found this when I zoomed in really close, but hopefully it shouldn't take too long to rebuild.

Ender what CAD program do you use? ive got a copy of Pro-Desktop free off my school but its an absolute bitch to use haha
I've never even heard of Pro-Desktop. For this I'm using Rhinoceros 4.0, since I'm most familiar with it. If you've ever played with Google Sketch up, think of Rhino as the super advanced cousin of it. I do have Solidworks 2009 which I have had only a small amount of experience with. I also have a newer program called Alibre Design which I've yet to install and try out, but it's suppose to be feature based like Solidworks. The advantage of Solidworks and Alibre is the ability to create assemblies with constraints, so you can fully test and manipulate the parts working with each other. Unfortunately I don't know much on how to do it. Really I should learn Solidworks so I can build assemblies, and it would also make it easier to import into Master CAM, the program that converts the parts into G and M code that the CNC machine uses to cut.
nice i can only do really simple stuff like extruding certain measurements then pieces them all together to make something. Pro-Desktops sort of the stripped down version of google sketch really its a bit naff
You can download a trial version of Rhino for free. Pretty much the full program, the only limitation is that you can only save 25 times. It comes with the same manual I used to learn it. [URL]http://download.rhino3d.com/rhino/4.0/evaluation/download/[/URL] I'm going to spend a few hours right now working on the BR. Fixed the upper receiver yesterday but you wouldn't notice the difference if I posted the pictures.
cheers i'll try and keep the save rate low haha, im like OCD when it comes to detail in things though so the weapon might take ages but its something to be proud of when your done
If anyone wants to see me working on the BR I'll be in the Chat. [url]http://tinychat.com/facepunchgearwhores[/url] [editline]03:44PM[/editline] Here's the current Ver 1.09 of the Battle Rifle. The Carry handle external work is more or less complete, just need to round off the corners and hollow it out for an ammo counter. I'll need to figure out how to mount it too, but I'm thinking of using the same method of the G36 carry handle, slide it on and lock it down with screws. I've added a to scale Mil Spec 1913 5 inch rail to the carry handle as well. The pistol grip area is currently being working on. I've shaped it so a standard M4 AEG grip should slide on it, but no threaded holes have been made yet. I think I'll have to tamper with the original design of the BR to make it accept a MOE grip, due to the extra part that hangs off the back to create a larger grip.

Took a break from the pistol grip and worked on the hanguard, only to be faced with the limitations of Rhino. I extruded the hanguard, then tried to cut a profile from a different view (Top) then round the edges off. Well unfortunately I get a bunch of zero thickness surfaces extending everywhere when I do this. It's going to be a while before I get a good looking handguard. This is the best I got so far, not nearly as curvy as I wanted though. Due to it's complexity I think the hanguard will need to be 3D printed.

[URL=http://img230.imageshack.us/i/1104d.jpg/][IMG]http://a.imageshack.us/img230/7957/1104d.th.jpg[/IMG][/URL] But why stop there? Lets toss on an EOTech and half of a M4 RIS handguard and mash 2 of them together. I sort of like the tactical BR look myself. Needs some obvious refinements, but it could work.

Looks pretty kick ass so far.

Damn you Kawaii :ninja:'d
I already see your problems with selling it but what would this be priced at? Since those halo SOCOM pistol attachments were like 400 dollars, an entire gun must dip into the thousands.
Lets find out. I'll be using prices from Mcmaster Carr. They supply tools, material and all kinds of shit. Costs tend to be higher due to the fast shipping times. Order it by 5pm and it will be there the next morning. [URL]http://www.mcmaster.com/#[/URL] Lower Reciever 36" x 6" x2" block of 6061 Aluminum = $217 (ID# 8975K269) Upper Receiver 36" x 4" x2" block of 6061 Aluminum= $150 (ID# 8975K267) Not as bad as I thought. You can see why cheap chinese companies like pot metal and molds compared to CNC milling a solid block of aluminum. E1 Ver.3 or Ver.6 Gearbox ~ $100 tops Inner Barrel $40-$60 Hop-up Chamber $15 M4 mag catch ~ Free, got a spare So roughly $550 for basic materials and parts, probably more. This is not including the cost of having a company actually machine it, which will cost a significant amount due to some of the unusual shapes. There will probably be excess material left over from the 2nd block, so that should fill out some of the internal components. The outer barrel I'm still deciding on. Making a full length barrel from gearbox to outside the gun requires a special lathe, properly named a gun lathe, to drill a precise hole all the way down. I'm thinking about just using a shorter outer barrel that starts just before the front of the gun and have some smaller supports inside holding the inner barrel.
This will be amazingly badass when and if it gets finished. In the games it looks like it's made out of a polymer though... wouldn't that be cheaper?
Depends on what type of plastic you get. Some special plastics can cost much more than aluminum. Looks like polypropylene might be the way to go. Can get a block 36" x 12" x 2" for $135 and it should be enough for the whole project. Advantage of this is it's non-toxic, unlike PVC which lets of toxic fumes when you cut it. Didn't see any ABS plastic in this size, closest they had was 24" x 12" x 2", too short to work. And even then it was $257.
You should so do Mass Effect 2 weapons.
Better yet, Borderlands.
