Magpul MBUS Pro Flip-Up Backup Iron Sight Set Black

Made from case hardened steel with a corrosion resistant, melonite finish, these flip up sights fit all 1913 Picatinny rails. Both sights have positive detents to keep them secured at standard AR sight height when deployed, but low profile when stowed. Dual aperture rear sight features a tool-free windage adjustment and is only 3/8" above the rail when stowed. Front sight has a finger adjustable elevation knob on the post, eliminating the need for any tools and sets 7/16" above the rail when stowed. Narrow width of the front sight makes it compatible with most IR aiming laser and light installations. Mfg: Magpul SPECS: Steel, melonite finish, black.
