Anyone else notice this about the BR?

When I first watched the E3 Campaign demo for Halo 4 I thought Chief was using the DMR. I didn’t hear or see 3 shot bursts, I only saw 1 shot. Then, a friend was talking to me about it and mentioned something about the BR in the campaign demo.

Does anyone else think that the burst is too fast? It’s hardly noticeable that it’s a burst weapon…

Sorry but I don’t agree. I heard the bursts, and think it sounds amazing. Best it’s ever sounded.
