Magpul MBUS PRO Steel Backup Sights, Rear Sight , Black
The MBUS Pro (Mogul 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, wind age adjustable Rear and no-tool, elevation adjustable Front excel in all 1913 Pica tinny rail mounting applications. Positive detents keep the MBUS Pro Front and Rear at standard sight height when deployed, and so low when they are stowed that you'll never notice them until they're needed. Narrow width Front is compatible with most IR aiming laser and light installations for the professional user.
