Rugged and Durable Magpul MBUS Gen 2 Flip-Up AR-15 Polymer Rear Sight

The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The dual aperture MBUS rear sight is adjustable for windage and fits most 1913 picatinny rail-equipped weapons, but is specifically tailored to the AR-15/M16 platform.

The impact-resistant polymer construction provides lighter weight while absorbing shock, making this an incredibly durable sight. The spring-loaded sight is easily activated from both sides of the firearm so you can quickly engage a threat. The MBUS features protective wings to shield your apertures and further protect your sighting system.

Magpul was founded in 1999 with the intent of developing a simple device to aid in the manipulation of rifle magazines while reloading under stress. The company's name comes from this original product called the Magpul. Over the last 17 years, Magpul has continued to grow and develop using much the same mission and process with a focus on innovation, simplicity and efficiency.
