MAGPUL MBUS Pro Rear Back-Up Sight, Black (MAG276)

Vendor: Magpul



The MAGPUL MBUS Pro Rear Back-Up Sight, Black (MAG276) is a corrosion resistant all-steel back-up sighting solution that delivers maximum functionality and strength with minimum bulk at a price that's even smaller than its size. The dual aperture, windage adjustable Rear and no-tool, elevation adjustable Front excel in all 1913 Picatinny rail mounting applications, including rail-height gas blocks.

Positive detents keep the MBUS PRO Rear at standard AR sight height when deployed, and so low when it is stowed that you'll never notice it until it's needed.
