Low Profile, Tool Free, Polymer Backup Sight
Combining the best features of Magpul’s polymer and steel backup sights, the new MBUS rear sight truly is a next-generation sight. With rapid push-button deployment, tool-free windage adjustment, and a sleek profile on par with the MBUS pro, this rear sight also comes in at a price point far below the all-metal options on the market.
This sight makes a perfect companion to a fixed A2-style front post, or with the MBUS Gen 3 Front Sight. If you’re looking for a full set, check out the Gen 3 MBUS Front and Rear Sight kit!
Easily Adjustable Windage and Aperture
One of the great things about the Gen 3 MBUS sights is that they’re entirely tool-free for adjustments. No bullet tips or one-off tools, just your hands and the windage drum. The rear aperture is also much easier to operate than Magpul’s previous generation of sights. Quickly flip using the pad of your thumb from a narrow aperture for accuracy, to the wide aperture for visibility and speed in close quarters.
