Product Description
The Magpul MBUS 3 Rear Sight delivers a low-profile, lightweight, and rugged backup aiming solution for modern sporting rifles. Significantly reduced in size compared to earlier MBUS designs, it measures just 0.55 inches high when folded and 1.38 inches at its widest point, while weighing only 30 grams with hardware. Constructed from Magpul’s impact-resistant polymer, this rear flip-up sight is durable yet light, and deploys instantly via an ambidextrous spring-loaded push-button. When deployed, it sits at standard AR height and features windage adjustment with a rapid-select rear aperture system for fast target acquisition. Compatible with Picatinny rail-equipped platforms including AR-15, AR-10, M4, M16, M110, and SR-25. Made in the USA.
