Magpul MBUS PRO Rear Sight
The MBUS Pro (Magpul Rear Back-Up Sight) is a corrosion-resistant, all-steel back-up sighting solution that delivers maximum functionality and strength with minimum bulk at a price that’s even smaller than its size. The dual-aperture, windage-adjustable Rear and no-tool, elevation-adjustable Front excel in all 1913 Picatinny rail mounting applications, including rail-height gas blocks. Positive detents keep the MBUS Pro Front and Rear at standard AR sight height when deployed, and so low when they are stowed that you’ll never notice them until they’re needed. The narrow-width front is compatible with most IR aiming lasers and light installations for professional users.
