That is the "winged hourglass", yeah. Being a logo, it takes some artistic license to make it more graphical. I know it's on the stock of my BR85 as well as the "MISRIAH ARMORY" text elsewhere, but I don't recall seeing it on another weapon, off-hand. It might be on the new S99. I should check to see if it's mentioned on the BR85 ammo, since I'll need to add it there too.
Okay thanks RobTc! What do you guys think would be better, make the M68 round out of solid brass/copper, or make it a steel slug with brass/copper jacket? It would cost more but would be more realistic and would weigh a nice amount. How should I do the red/cyan color on the top? Anodized aluminum? Paint it? Some other way?
Bronze, not brass. Slightly different colour and is soft enough to self-lubricate. What I would do is electroplate a lathed steel slug in a copper coating and allow that to patina to the colour of bronze. That just needs a PC power supply or car battery and a copper sulphate solution.
I'm not so sure - as I'm aware, the Halo 4 Limited Edition lists the details of the BR85HB and the ammunitions type it uses, and lists the munitions as 9.5x40mm rounds.
That said, it's important to note that the game models often fluff it up - the Assault Rifle, I recall, has no way to fit 60 rounds into the magazine, at the ammunition type given, so it's worth instead working on what fits yourself.
I know they upped the power of the rounds when they started using heavy barrels, which typically just requires a hotter filling- and therefore more space in the casing to fit the extra powder. Usually the higher-powered rifle rounds out there are about double the length, or just under, of the actual bullet itself, which only has its back end crimped into the casing. So the 13x80mm total dimensions makes complete sense to me.
On the other hand, I was looking at the magazine and it looks closer to 20 rounds, not 36, but maybe if it's double-width and they zigzag down it might just about be doable. I could lay out a diagram for that to check.
Edit: Nah, comes out at 13 rounds. Now I'm stuck though, because it fires a specific size, and it would look weird if I dropped it down to 5.56mm or something in order to fit 36 rounds in there- which I don't even need to do, I'm only making the top one or two. I think I'll just go with 343i's lack of realism and stick to the game model. Make what it is, not what it "should be".

and that is straight out of the book let. and I still don't know why the DMR cost's more.
I'm guessing the DMR has a longer, more highly tuned barrel. Which itself seems to be the highest cost component of a system. Considering the simplicity of a sniper rifle, there's no reason they should cost ten grand or more more than a long barrel battle rifle with all their gas operated moving parts- unless you're paying for the higher engineering costs of the bigger barrel.
