Delivers Maximum Functionality And Strength Without Breaking The Bank!
The Magpul MBUS PRO Front Back-Up Sight is a great front-sighting solution for your AR-15 that can deliver maximum functionality without breaking the bank. This front back-up sight will keep your AR fully equipped on any tactical operation bringing more strength and reliability.
Designed with all-steel construction, it delivers extreme resistance to wear and corrosion with hardened case and finish made of Melonite QPQ.
Easy Installation – No Tools Required
The Magpul MBUS PRO Front Back-Up Sight is designed with dual-aperture and features an adjustable rear for windage. It has positive detents that can keep the front and rear MBUS PRO at standard sight height when deployed.
The design is compact and made with an adjustable elevation knob so no tools are required to install it in all 1913 Picatinny rail mounting systems – including those rail-height gas blocks. The MBUS PRO Back-Up Sight is also very low when they are stowed keeping a low-profile look on your AR. This ensures a clear distraction-free sight for your optics that you’ll hardly notice them until they are needed.
The narrow width front is compatible with most IR aiming laser and light installations for any professional users.
