The MBUS Pro (Magpul® 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. 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.
Case hardened and finished with Melonite QPQ for extreme resistance to wear and corrosion
Mounts on any MIL-STD-1913 Picatinny/STANAG 4694 rail
Windage adjustable with low-profile knob – no tools required
Positive detents in both the up and down positions
Standard AR sight height when deployed
Made in USA
