Lights mount on the gun's accessory rail — fitment is near-universal, so the grade reflects flood-vs-throw fit for this gun's use, not whether it bolts on.
Compatible Lasers
(11)
11 lasers that mount on the FN 545 Tactical. Lasers are situational — an IR aiming laser or illuminator earns its place with night vision (it does what a red dot can't), and a visible laser is a real aiming aid on a carry gun with no optic, though largely redundant once you mount a dot. Tagged by the role each fills, not graded.
