Now I’m going to randomly ask everyone a question.
Q. What’s your favorite gun in Halo 3?
Mine is the Covenant Carbine. I like it because it can be used for Close Quarters & Long Range. Plus it just looks cool.
Battle Riffle.
Uh, the BR.
BR
Duel Wield SMGs are the funnest weapons but the Battle Rifle is the best for sure.
Sentinel Beam 
The Battle Rifle by a LOOOOOOOONNNNNNNNNNGGGGGG shot. it was just so fun to use, and it defines a good player and the entire halo franchise.
It would have to be the Assault Rifle
Battle Rifle
Mauler FTW .
Flamethrower.
Dual Wield pistols
The BR.
Despite the fact that I hardly ever use it, I love the Brute Shot.
Battle Rifle.
