Magpul MBUS Pro Sight – Rear

Features

  • All-Steel Construction: Melonite® QPQ–finished steel body for extreme wear and corrosion resistance.
  • Positive Detented Lockup: Spring-loaded detents secure the sight in both deployed and stowed positions.
  • Rapid-Select Dual Apertures: Small (0.07″) for precision and large (0.19″) for rapid target acquisition.
  • Tool-Less Windage Adjustment: Knurled detent wheel provides ~0.5 MOA per click at a 14.5″ sight radius (0.4 MOA at 20″) without any tools.
  • Low-Profile Stowed Height: Only ~0.37″ above the rail when folded, minimizing snag points.
  • Co-Witness Deployment Height: Sits at standard AR sight height (1.41″ center of aperture to top of rail) when deployed.
  • Compact Dimensions: Stowed length ~2.1″, deployed footprint allows full co-witness with optics.
