Our line of front and rear self-illuminated back-up sights is renowned for its durability and user-friendly design. Crafted from fiberglass reinforced high-grade polymer, metal or aluminum, these rugged secondary sights are enhanced with tritium for reliability. They sit flush against the picatinny rail, maintaining a low-profile until needed. With a rearward operating spring, they can be swiftly flipped up into position when required. The elevation sight pin can be adjusted tool-free for added convenience. Available in configurations featuring either two dot or four dot rear sights, these low-profile options mount easily onto any picatinny rail. Their nighttime illumination is optimized to be visible yet not overly bright, preserving the sight picture in any lighting conditions. Whether day or night, in the event of optic failure, simply flip up these dependable sights to stay engaged and effective.
