Magpul - MBUS Pro® Sight – Rear

The MBUS Pro (Magpul® Back-Up Sight) is a corrosion-resistant, all-steel back-up sighting solution that provides maximum functionality and strength while keeping a minimal profile. It is designed to offer a lightweight, yet robust, iron sight system at an extremely affordable price.

The MBUS Pro Rear Sight is windage adjustable and features dual apertures, making it highly effective across a variety of distances. It excels in all 1913 Picatinny rail applications, including those with rail-height gas blocks. When deployed, the MBUS Pro Rear and Front Sights lock into standard AR sight height, and when stowed, they remain so low-profile that you won’t even notice them until they’re needed. The narrow front sight profile also ensures compatibility with most IR aiming lasers and light systems, ideal for professional users.

Made in the USA, the MBUS Pro Rear Sight is a high-performing, durable, and compact backup sight system designed for the most demanding situations.
