The MBUS (Magpul Back-Up Sight) Pro Sight Front, Hooded is an all-steel, back up front sight. The hooded front sight arm provides a profile that aids in faster sight acquisition while minimizing snagging. It’s also just as durable as Magpul’s other Pro sights thanks to a corrosion-resistant QPQ finish that delivers maximum functionality and strength with minimum bulk. When the Hooded Pro Front Sight is paired with the dual aperture, windage-adjustable MBUS Pro Sight Rear, it can act as a diopter style sight (aperture within an aperture) depending on its placement in relation to the rear sight. Used with the MBUS Pro Sight – Rear, the toolless, elevation-adjustable MBUS Pro Sight set excels in all applications, including when mounted on rail-height gas blocks. Detents keep the Hooded Sight at standard AR sight-height when deployed, and it remains out of the way when it’s stowed (measuring 1.71 from the sight base’s leading edge to the top of the hood). Two front-post widths (.040″ match or standard .060″) are available to fit shooters’ precision needs (the narrower width front is also compatible with most IR aiming laser and light installations for the professional user).
