Description
When your red dot's battery dies or your glass takes a hit, having a reliable set of irons ready to go makes all the difference. The NcSTAR VISM Pro Series flip-up combo gives your AR-platform rifle a low-profile, spring-loaded backup solution that stays out of the way until you need it. Both sights sit on the same plane and fold flat, so they clear the space under most optics without any wrestling for room on the rail.
How the VISM Pro Series Flip-Up Set Handles
Deployment is about as simple as it gets. Press a button and the spring-loaded sight snaps up into position, ready to run. The front sight uses a classic A2 post that's fully adjustable for elevation, giving you that familiar sight picture most AR owners already know by heart. Out back, the rear offers A2 dual apertures, large and small, so you can pick the right window for close-in work or tighter shots at distance. A knurled windage knob handles left-and-right zeroing without needing a bench full of tools.
Build and Fitment on the VISM Pro Series Sights
These sights pair an aluminum main body with a steel A2 front post and steel rear aperture, which keeps things light without giving up durability where it counts. The front sight height is matched to handguard rails, monolithic receivers, and gas blocks that sit at the same height as the AR receiver's Picatinny rail, so you get a proper co-witness setup. Everything clamps onto standard Mil-STD 1913 Picatinny rails, and a mounting tool comes in the box to get you squared away.
For anyone building out an AR or just wanting a plan B behind their primary optic, this VISM combo covers both ends of the rifle in one purchase. It's a practical, no-drama backup that folds down out of sight until the moment you need it up and running.

Frequently Asked Questions
Will the VISM Pro Series flip-up sights co-witness with a red dot or fold under a scope?
Yes. Both sights use a low-profile design that folds flat to clear the space under most optics, and the front sight height matches rails, monolithic receivers, and gas blocks that sit even with the AR receiver's Picatinny rail. That same-height setup means they line up for a proper co-witness behind a red dot. When you don't need them, they tuck down out of your sight window.
What are these NcSTAR VISM sights made of?
The main body is aluminum, while the front A2 post and rear A2 aperture are steel. That combination keeps the set light on the rail without giving up durability at the wear points. It's a sensible balance for a backup sight that spends most of its life folded down.
How do the VISM Pro Series sights adjust for zero?
The front sight post is adjustable for elevation, and the rear aperture handles windage through a knurled knob you can turn by hand. That splits your adjustments the same way a traditional A2 setup does, so anyone familiar with iron sights will feel right at home. Take your time getting them dialed and they'll hold your point of aim.
What rifles do these flip-up sights fit?
They mount to any standard Mil-STD 1913 Picatinny rail, which covers most AR-platform rifles and other flat-top setups. A mounting tool comes in the box so you can get them clamped on without hunting for extra hardware. Just make sure your rail sections give you enough room to space the front and rear apart for a good sight radius.
