Steps:

1. Equipped Gauss Barrel on a [Revolver of the Wanderer] (or an item glamoured as the [Revolver of the Wanderer]).

2. Noticed that the Gauss Barrel does not align with the barrel of the [Revolver of the Wanderer], the centerpoint of the Gauss Barrel is below the centerpoint of the barrel of the [Revolver of the Wanderer].
