Scalarworks PEAK/02 | Folding BUIS

The Scalarworks PEAK/02 Folding Iron Sights are designed as a backup iron sight (BUIS) system for rifles equipped with MIL-STD-1913 Picatinny rails, including AR-15 pattern platforms and other compatible firearms. The sights feature a folding, low-profile design intended to reduce rail space usage while remaining accessible when deployed. Models are available in configurations compatible with 1.57" and 1.93" optic height setups, commonly used for lower-third co-witness with many red dot optics.

Each sight is CNC-machined from 7075-T6 aluminum with 4140H steel components, and finished with Type III hardcoat anodizing and flash-nitrided steel surfaces for durability and corrosion resistance. The front sight provides manual elevation adjustment, while the rear sight offers windage adjustment, both with 0.5 MOA per click increments at a 15" sight radius. The rear sight includes same-plane flip apertures, and the front sight uses a non-rotating 0.053" sight post. The sights mount directly to standard Picatinny rails and are manufactured in the United States.
