BUIS and night vision setups

Night vision (NV) usually pairs with illuminated optics or IR lasers—not plain black irons. Flip-up BUIS remain a daylight/white-light backup. The FBUIS-B listing does not claim tritium or NV-compatible inserts.

How BUIS fit an NV-capable carbine

• Passive NV behind a red-dot: you still want fold-flat irons for day / white-light failure, not as the NV primary.
• Active IR laser/illuminator: aiming often bypasses irons entirely under NODS.
• White light only: large CQB aperture helps; still no glow from FBUIS-B itself.
