I just noticed you've got both the GPR21 and ATB140 equipped. The former requires two hands to use, as stated in the entry ("carried, two hands"). The rationale is the GRP21 packs a heavier punch than the AFC-40/L and needs to be braced with both arms for stability. The bazooka is propped up over the shoulder, so it only needs one hand at most.
So you'll have to decide between them or take the bazooka and the AFC-40/L.
