The MBUS Pro (Magpul Back-Up Sight) is a corrosion-resistant, all-steel front back-up sighting solution that delivers maximum functionality and strength with minimum bulk. Case hardened and finished with Melonite QPQ for extreme resistance to wear and corrosion. Positive detents keep the MBUS Pro Front Sight at standard AR sight height when deployed, and so low when they are stowed that you'll never notice them until they're needed. The no-tool, elevation adjustable front sight excels in all 1913 Picatinny rail mounting applications, including rail-height gas blocks. The narrow width of this front sight is compatible with most IR aiming laser and light installations for the professional user. Made in the USA. Weight with hardware: 1.5 oz. Height above rail, stowed: ~0.43". Length, stowed: 1.6".
