The Magpul MBUS Pro Back-Up Sight is a corrosion-resistant all-steel back-up sighting solution delivering maximum functionality and strength with minimum bulk. They are case-hardened and finished with a ferritic nitrocarburizing process for extreme resistance to wear and corrosion. The dual aperture, windage adjustable Rear and no-tool, elevation adjustable Front are great for all 1913 Picatinny rail-mounting applications, including rail-height gas blocks. Positive detents keep the sight at standard AR sight height when deployed, and low when it is stowed so you'll never notice it until it's needed. Narrow-width Front is compatible with most IR aiming lasers and light installations for professional users. Made in USA. Available: Front Sight, Rear Sight.
