Magpul® Back-Up Sights (MBUS®) Pro

When situations arise and a shooter’s primary rifle optic malfunctions, gets damaged, or loses battery power, it could become a life or death situation. However, running Magpul® MBUS® Pro sights as a back-up will keep the shooter in the fight and confident in their weapon. The shooter can quickly reengage offensively when resorting back to old school standard iron sights. However, the MBUS® Pro front and rear sight combination are superior to traditional iron sights.


The MBUS® (Magpul® Back-Up Sight) Pro is a corrosion-resistant all-steel sighting solution that delivers maximum functionality and strength and mounts to a MIL-STD-1913 Picatinny or STANAG 4694 rail with minimum bulk. The sleek combo has positive detents that keep the MBUS® Pro Front and Rear at standard M4/M16 height when deployed.  The MBUS® Pro has a small footprint on the rail while offering a very low profile, even compared to its Gen 2 Polymer MAGPUL® brother.


The user can mount the MBUS® Pro sight to a gas block without melting or deforming due to the all-steel construction.  The sights have a narrow base to make them compatible with most IR aiming laser and light installations for the professional user. Additionally, the elevation adjustment knob & windage knob can be turned by hand and require no tools to manipulate. The rectangular front sight post also has a selectable Standard & Match option.


Another MBUS® option is the Pro Offset Sights. These come in handy when the primary optic malfunctions or gets damaged. This 45-degree angle provides the shooter with an accurate iron sighting solution.

The REAR sight, with its sleek low profile, has sturdy positive detents in both up & down positions. In either mode, the desired position remains with no likelihood of slipping. However, making adjustments by hand takes a fair amount of finger strength. The MBUS® Pro Front & Rear combo weighs in at 3.3oz with hardware. The MBUS® Pro set up can be bought either in individual components or as a set.
