(You should keep it on that Type 1 comment, lol, these two are basically the same).

It's not a weapon. It's an auxiliary piece that modifies the daytime spotting attacks giving both cut-in and double-tap daytime attacks (and also single attack), hence some people called 2x main guns + AP Shell setup a "mixed setup".

Also comes with bonuses for the ship that equip it.

...but main + main daytime cut-in has higher chance to come out than double-tap so seeing a double-tap with 2x main + AP Shell setup can be a rare ocassion.
