Product Overview
Magpul MBUS 3 Rear Sight is a compact, spring-loaded backup iron sight built for AR-style rifles. It folds to just 0.55 inches above the rail yet deploys to standard A2 rear sight height in a heartbeat. Housing dual apertures in impact-resistant polymer, it adds windage-adjustable precision with a dependable detent knob. The ambidextrous push-button deployment means you stay ready, whether it's optic failure or friction training.
Match it with LPVOs, magnifiers, or red dots—it clamps solid to any MIL‑STD‑1913 Picatinny rail and takes up minimal real estate on your rifle.
