Magpul MBUS Rear Sight

873750-MAG248

The Magpul MBUS Rear Sight is a folding flip-up sight designed specifically for AR platforms. This Magpul backup sight is constructed of impact-resistant polymer that resists operational abuse. A spring-loaded flip-up system easily deploys from either side, where detent and spring pressure keep the sight in place. Protective wings prevent damage to the aperture to ensure accurate aim, while a detent knob offers quick windage adjustment. Compatible with most 1913 Picatinny receiver rails, the Magpul MBUS Rear Sight offers a dual aperture backup sight tailored to AR15/M16 platforms.
