Magpul Mbus Rear Flip Sght Gen 2 Od

The Magpul MBUS Rear Flip Sight Generation 2 in Olive Drab is a spring-loaded, dual-aperture backup sight engineered for AR-platform rifles equipped with Picatinny rails. Designed as a low-cost, injection-molded alternative to fixed iron sights, the MBUS Gen 2 rear sight provides reliable windage adjustment and rapid target acquisition when primary optics fail or require backup capability during critical operations.

This flip-up rear sight features protective wings that shield dual, same-plane apertures, reducing glare and improving sight picture clarity in variable lighting conditions. The spring-loaded mechanism activates from either side of the sight or via the top activation button, enabling rapid deployment without removing the firearm from shooting position. Windage adjustment allows operators to zero the rear sight independent of the front post, a critical capability for maintaining zero shift when switching between different optics or returning to irons. At just 0.13 lbs, the minimal weight addition doesn't burden carbine or rifle platforms, and the compact profile—measuring 4.25 x 1 x 7.5 inches—integrates seamlessly on standard Picatinny-equipped uppers.

The MBUS Gen 2 is purpose-built for patrol rifles, entry weapons, and duty carbines where backup iron sights meet modern tactical requirements. It serves law enforcement, military, and civilian shooters who prioritize reliability over cost and demand a sight that functions after thousands of rounds downrange. The Olive Drab finish blends with modern Cerakote-finished platforms and provides a professional appearance suitable for duty or training environments. This rear sight is specifically tailored to AR15/M16 geometry, ensuring proper sight radius and target engagement capability when paired with a compatible front post.
