Yankee Hill Machine Co Flip-Up Rear Sight – Black

The Yankee Hill Machine Co Flip-Up Rear Sight delivers a reliable, low-profile backup sighting solution for AR-15 and other Picatinny-equipped rifles. This spring-loaded rear sight locks securely in both the upright and folded positions, providing quick deployment when your primary optic fails or when backup iron sights are needed. Precision-machined from steel with a durable black finish, it offers windage adjustment for zeroing and co-witnesses with most red dot and holographic optics.

The sight mounts to any MIL-STD-1913 Picatinny rail and features dual apertures—a small aperture for precision shooting at distance and a larger aperture for close-quarters speed. The spring-loaded flip mechanism is positive and audible, ensuring the sight stays in position until you need it. Pair with a compatible front sight for a complete backup iron sight system.
