NcStar VISM Pro Series Flip-Up Rear Sight

The NcStar VISM Pro Series Flip-Up Rear Sight is a low-profile spring-loaded backup sight designed specifically for AR-platform rifles and tactical carbines. This sight is essential for operators who rely on optics and require a backup solution that minimizes interference with primary optics. It is built to meet the needs of law enforcement, military trainers, and serious rifle enthusiasts.

Constructed from durable aluminum, this rear sight deploys with a single push-button action and folds flat when not in use. The dual-aperture design offers both large and small apertures for versatile target acquisition at various distances. Full windage adjustment via a knurled knob allows for precise zeroing without the need for specialized tools.

The VISM Pro Series is particularly beneficial for those engaged in advanced carbine courses or home-defense scenarios, providing a reliable secondary aiming solution. Its spring-loaded mechanism ensures a consistent return to battery, while the A2-style aperture design maintains compatibility with standard AR-15 training and marksmanship standards. This sight is a critical component for anyone who understands the importance of backup iron sights in modern optics-dominant configurations.
