Halo 2 Battle Rifle

I have asked about this in another this in another part of the forum but maybe someone here can shed some light on my question. I am an SR119. I have opened a huge amount of the gold REQ packs. I have yet to see the Halo 2 battle rifle. Is there a specific game type I must play or a certain mission in the campaign? Is it just “the luck of the draw”? The reason I ask is that most, if not all of the players I have seen with this rifle have been ranked anywhere from 30 to 60. Thanks for any info.

100% luck of the draw. My friend opening nothing but gold and silver packs, and already owning 4 DMR skins didn’t get his first actualy DMR until nearly rank 70. Just random chance.

Please don’t cross-post topics thanks :slight_smile:
