I was thinking of about could be a replacement for the BR/an upgrade.
An Scoped Automatic/Semi Antimaterial assault rifle with 60 ammo clip and 300 for full capacity, it fires a 5 shot burst every single trigger pull with the same ROF as the BR, however if you hold the trigger after a burst it will almost immendiatly fire at an slight lower ROF of an AR but spread will be present, but not as nearly much as an standard AR at first, but the longer you hold the trigger, the wider the spread will be and it will increase quickly preventing spamming with it.
it will take 19 shots to take down shields, 1 for the head, and 8 to the body making it harder to headshot while using it as an AR.
No flame please becuase this is just an small idea/suggestion 
Peace.
I think they created the weapon already. It is something with like a 2 shot burst.
lol, dude as soon as i posted an idea about a new AR i looked up and found this thread, lol i guess great minds think alike. Really like the idea.
Sounds pretty good, I think 19 might be a bit too much for just taking down shields (it was 18 to kill with Reach MA37)
I would rather see more diversity in terms of weapon firing rate. Possible toggling modes.
Or maybe that isn’t Halo.

Well, that might be a problem for realism’s sake lol.
But really it’s about the same as a BR: 11 shots to for shields and 1 to the head.
An interesting thought you have there, with the burst transitioning to automatic, but something like that sounds better for a machine gun. You’re looking for something to fill a gap left by the BR I assume, but guns with complicated firemodes should be the ones you pick up. A replacement for the CE magnum is more in order here.
If you haven’t played it yet, Halo 1 has the best utility, the famous magnum. It’s a functional thing, but it’s the most simple gun in the game. It’s the sense of mundane basic in the weapon that makes you switch it away, because other weapons have more complicated firing patterns and other dangers. The magnum was just something in your pocket, so to speak. Your suggestion is far too complicated for something to spawn with.
There should be a single weapon that incorporates the magnum, AR and BR. A heavy cal, slow-firing machine gun that can be tapped to fire semi and can lay down a rain of heavy fire on auto. Something like this. Not that exact weapon, but a simple mechanism that basically does work. Something really basic with a lot of class.
I think the BR was the best weapon to come to Halo. It was such an effective weapon at all ranges, but almost overpowered in the hands of a good player. Created a skill gap and made the experience more fun.
lol awesome, as long as they ditch the DMR completly, tame down the stupid pistol because the BR should be the main weapon, it was once known for being the main weapon in most halo games till stupid Halo:Reach came out.
