Instant Confidence When Optics Quit

The SIG SAUER Gen 2 Flip-Up Rear Sight 1701478-R is your fail-safe answer when a red-dot battery dies at the worst time. This top-mounted deployable iron sight folds flat until needed, then rises with a crisp aperture that keeps you on target in seconds—no tools, no fuss.

Built Tough for Real-World Use

A rugged metal body shrugs off recoil and rough handling, while the hard black finish blends with any duty or range carbine. The sight locks securely in both the up and down positions. A Picatinny clamp installs quickly on any MIL-STD-1913 rail, and the ambidextrous design suits left- and right-handed shooters alike.

Fast, Simple Zero Adjustments

Precise windage clicks let you dial in without extra gear. When paired with a matching front post, the sight co-witnesses perfectly with popular optics such as the SIG Romeo5, giving you an instant backup that never relies on batteries. Flip it up, get your sight picture, and stay in control.
