The only AR I can think of that has x3 on the card for damage is the Kitten, but it’s not a burst fire rifle. It’s a Vladof, which are fast firing, fully auto ARs. It’s also a really good weapon so I could see why you liked it so much, if that’s what you’re looking for.
Edit: The legendary Dahl AR the Veruc also has x3 for damage on the card and is a burst fire rifle. It’s also a good weapon, but loses a little effectiveness with its unique firing pattern. I personally love a corrosive version versus robots since the spread of the weapon can hit multiple crit spots.

The closet thing I can think of would be a double tap rifle. It says x2 on the damage card and fires a two round burst for 2 ammo (IIRC). Maybe that’s the weapon?
