I disagree, the bozar is one of my favorite weapons next to Medicine Stick and Lucky. The Bozar really shines in mid range combat when fighting a group of enemies, and I knid of think of it as a mid range light machine gun (which it is). It has most of the strengths of the LMG, it's just better suited for mid range combat rather than close range.
At first.
But I like the weapon enough to jump through hoops so I said "what can this weapon do that the LMG or for that matter any rifle can't do?"
Answer: the fire rate with precision.
So I changed one of my traits to Fast Shot with the Sink auto-doc and chose Ain't Like That Now to pump its fire rate to 21 ROF. With match ammo, Rapid Reload (lol) and high Agility I am blazing through enemies reloading almost instantaneously dealing over 600 DMG in 1.3 seconds. Deathclaws with their huge heads fall so easily with AP rounds.
EDIT: Fast Shot also reduces AP cost and with concentrated fire perk this gun is also beasting in VATS.
