I am dmr and battle rifle
I’ll probably have setups with each. Gotta show them all some love.
Light Rifle and DMR. Although I will tinker with the Carbine a little bit.

Probably the DMR (as stats show it to be the most powerful), and then the carbine! Light Rifle seems gimmicky and I can’t stand the new look of the BR!
I will only use Carbine.
Covie Carbine.
DMR will always be my favourite. The Light Rifle looks awesome. Carbine looks so much fun to use. And I hope the Battle Rifle is better than Halo 3’s version. I liked it in Halo 2, but Halo 3 ruined the weapon for me.
From the gameplay I’ve seen I’m really sure the DMR will be my weapon again.
But for the others, I really want to try them out myself first.
Gotta Try Them First but right now i would like to go With BR & Carbine!!
BR and carbine.
BR and Assault Rifle.
Whatever happens to be on the ground when I need it.
Whichever turns out to be the most powerful at any range, likely the DMR. However, I do hope the Light Rifle proves a useful weapon; aesthetically it’s gorgeous, and I’d love for it to be a viable competitive choice.
Everyone has a time machine but me 
BR and Carbine for a while, but judging by gameplays I’ll probably end up settling on the DMR instead of the BR.
LR definitely. Probably carbine or DMR otherwise.
from using all over the weekend at eurogamer i would say that the DMR is best then BR then LR but they all are good i guess its just personal preference
Light Rifle/BR and Carbine over here.
I played Halo 4 at Eurogamer Light Rifle is AWESOME!
LR/Carbine
DMR/Carbine
I don’t really have a favorite. I expect to use all of them regularly, including the automatics. Of course I will gladly pick up whatever’s laying on the battlefield. 
AR and Magnum.
