The ALDA 5.56 sacrifices damage per shot for the fast rate of fire of the LMG class. Despite its damage output and magazine capacity which aren't impressive compared to other weapons of its class, this weapon is still able to perform extremely well due to it being available to a Defender.
Originally, this machine gun used to have a unique feature in which its hipfire spread did not increase the longer it was fired. Instead, the spread use to decrease with sustained fire. This has since been changed as of Update 3.3.2.
