Magpul MBUS 3 Rear Sight: Evolved Backup Sight Excellence

The MBUS 3 represents the next generation of Magpul's legendary backup sight line, combining the proven strengths of the original MBUS with the refined aesthetics of the MBUS Pro. This is a serious tool for serious shooters who understand that a quality backup sight is not optional—it's essential.

Compact Design, Maximum Durability

Magpul engineered the MBUS 3 to be significantly smaller than its predecessor while maintaining full functionality. When folded, it stands just 0.55 inches high and measures 1.38 inches at its widest point. Despite its compact footprint, it weighs only 30 grams with hardware—light enough to add negligible weight to your rifle.

Constructed from impact-resistant polymer, the MBUS 3 delivers the durability you need in the field without the weight penalty of steel. It will not fail you when you need it most.

Intuitive Operation

Ambidextrous Push-Button Deployment: Spring-loaded technology allows rapid deployment from either side of the rifle. No fumbling. No confusion. Just smooth, reliable operation.

Rapid-Select Aperture System: Windage-adjustable aperture lets you dial in your zero quickly and precisely. The system is designed for shooters who understand that accuracy matters.
