That...turned out not to be the case.
While it is true that the A.R. delivers up reasonable damage per bullet to bypass the DT problem that other automatics have without being limited to only using armor piercing rounds... and true that it has less spread than most other automatics... I'm finding it not very great. Mainly it boils down to two problems. The accuracy simply is not sufficient for a weapon this heavy, shooting ammo this expensive and heavy. Its lethality at point blank range where its rounds actually connect is not appreciably better than other options (my favorite, hunting shotgun with slugs) due to its low rate of fire and imprecision, and it has absolutely no ability to project firepower at a distance. Combine this with the laughably low durability (it's a heavy duty military weapon designed for automatic fire and trench warfare, that is 33% less durable than a civilian-issue hunting rifle firing the same cartridge?) that punishes you for actually using the thing on automatic.
Ideally it should be a decently accurate (0.5) semi-auto rifle when free aiming (the 1918 and 1918A1 BAR were select fire), and bump the burst in VATS to 3 rounds. And for the love of gods, increase the durability. The BAR was not known to be a maintenance hog.
