I agree. It's faster than Scar, and does more damage than the ACR. The silencer actually improves it and you don't always need stopping power. Just very well-rounded gun. Also few people whine about it, which makes it easier to concentrate on playing the game rather than muting the entire lobby.
i got the veteran challenge so quick on this compared to other weapons. ill never stop using it along with the carbine. the ACR without stopping power doesnt go so hot with me but another favorite.
