They look great. Curious why they decided to label the AR MA5D.
EDIT: Why does the sniper never have an ejection port? And where is the mag release for the DMR? Gunsmithing 101.
Ugh, looks and sounds like gun they scrapped from Reach.
Thought so some how I knew it was a railgun.
> The ARC-920 Railgun is a compact-channel linear accelerator that fires a high-explosive round at incredible speed, delivering both kinetic and explosive force to both hard and soft targets alike.
Hmm spartan laser cross rocket launcher?
I am liking the Raingun thus far. 
Well hell, looks like a bunch of people went and called this one early…
…But, despite now having a Sodding Clue as to how it’s going to fully work in game, it’s a somewhat interesting concept and I look forward to seeing/hearing more of it…
HALO 4 IS TURNING INTO QUAKE! ZOMG!!!

Can’t wait to use it.

I am inclined to agree with you, sir/m’am (sorry, don’t know your gender).
Going to see it as the concussion rifle/bruteshot role in Halo 4.
Now we just need the Chronoscepter from the original Turok.
Sounds like a portable Gauss warthog turret.
Reminds me of a human version of the concussion rifle.
It’s rounds are both kinetic and explosive. I’m feeling like the chances of the grenade launcher returning is slimmer and slimmer. 
So the rail gun is nothing more than an updated Concussive Rifle/Brute Shot?

Sure, I’ll take that.

New look, new name.
Same with the br.
