Suitability is general guidance based on the platform's typical effective range — not a hard rule. Your load, optic, and intended use may shift it.

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 EAA Witness 2311. 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.

Civilian-legal units only (eye-safe IR). Fitment is the rail; whether you need one depends on your setup, so these are positioned by role rather than scored.
