Magpul Mbus Pro Offset Sight Rear

The Magpul MBUS Pro Offset Sight Rear is a battle-hardened backup aiming solution designed to work in conjunction with magnified optics mounted on M1913 Picatinny rails. Unlike traditional co-witness setups, the offset configuration allows the shooter to rotate the rifle 45 degrees and access a fully functional iron sighting system without removing or repositioning the primary optic—critical when the magnified sight fails or when engaging close-distance targets requiring rapid acquisition outside the optic's minimum focus distance.

Built from Melonited steel, the rear sight delivers exceptional corrosion resistance and dimensional stability across extended shooting sessions. The positive detented lockup ensures the sight stays in the deployed position under recoil, while tool-less windage adjustment allows field zeroing without requiring a multi-tool or armorer's wrench. The sight's compact profile—3 inches in height and just 0.19 lbs—adds negligible weight to the platform while maintaining sufficient sight radius for precision work. The 45-degree offset mounting eliminates the bulk and weight penalties of traditional co-witness rear sights.

This sight is purpose-built for operators running magnified optics on patrol rifles, designated marksman rifles, or competition platforms where backup iron sights are mandatory. Whether training in a three-gun match, deployed on a rifle team requiring redundant sighting systems, or conducting maintenance on primary optics in the field, the MBUS Pro Offset Rear Sight provides immediate, reliable aiming capability. The offset design preserves sight radius while keeping the upper receiver clean and uncluttered—particularly valuable on short-barrel platforms where receiver real estate is limited.
