The Magpul MBUS 3 OD Green Folding Rear Backup Sight is significantly more compact than the original MBUS, measuring just 0.55″ high when folded and 1.38″ at its widest point, while tipping the scales at only 30 grams with hardware. Drawing design cues from the MBUS Pro line, the MBUS 3 is constructed from Magpul’s impact-resistant polymer, delivering a lightweight platform with exceptional durability. Spring-loaded technology allows rapid deployment via ambidextrous push-button activation. When extended, the sight reaches standard AR-height and features a windage-adjustable, rapid-select aperture system for quick target acquisition and precise adjustments.
The MBUS 3 delivers 0.5 MOA (0.606″/100m) per click with a 14.5″ sight radius, or 0.4 MOA (0.439″/100m) per click with a 20″ sight radius. Ambidextrous push-button deployment and rapid-select rear aperture system provide shooter flexibility across any shooting position. Made in the USA.
