The NCStar Vism Pro Series Flip-Up Front Sight is a low-profile backup iron sight designed for AR-platform rifles and other firearms with Picatinny rail systems. Built for shooters who want a reliable, spring-loaded front sight that stays out of the way until needed, this sight deploys with a push of a button and flips down when not in use—ideal for co-witness setups with optics or for keeping your sight picture uncluttered during magnified shooting.
The sight features an A2-style front post with elevation adjustment, allowing you to dial in your zero without guesswork. It's engineered to work seamlessly on handguard rails, monolithic receivers, and gas blocks that sit at the same height as your AR's receiver Picatinny rail, making it compatible with most modern rifle builds. The aluminum body keeps weight minimal—just 2 ounces—while the steel A2 post delivers the durability you expect from a backup sight that might see hard use in the field or on the range.
Installation is straightforward: the sight mounts directly to any Picatinny Mil-STD 1913 rail, and a mounting tool is included in the box. Whether you're running an optics-primary setup and need an emergency iron backup, or you prefer irons as your main sighting system, this flip-up front sight offers the low-profile convenience and proven design that keeps your AR ready for whatever comes next.
