The MBUS Pro (Magpul Back-Up Sight) is a highly functional and durable sighting solution made entirely of steel that is resistant to corrosion. It is designed to be compact yet strong, and is priced affordably despite its high quality.
The rear of the sight features dual aperture and is windage adjustable, while the front sight can be adjusted for elevation without the need for any tools. These features make it suitable for use with all 1913 Picatinny rail mounting applications, including rail-height gas blocks.
When deployed, the MBUS Pro Front and Rear sights are held at a standard AR sight height, thanks to the positive detents that keep them in place. When they are stowed, they are so low that they are hardly noticeable.
The narrow width front sight is compatible with most IR aiming laser and light installations, making it ideal for professional use. Additionally, it is made in the USA.
*NOTE: All MBUS Pro Front Sights now come factory-equipped with the Enhanced Front Sight Post. There is no need to order one separately unless you are retrofitting an older MBUS Pro front sight. Enhanced Front Sight Posts are not compatible with standard MBUS polymer sights.
