Strike Industries Polymer Backup Sight Set for AR-15, Folding Dual-Aperture, Tool-less Adjustments SPBUS

Product Description

The Strike Industries SPBUS Strike Polymer Backup Sights deliver a low-profile, budget-friendly sighting system for AR-platform rifles. Built from lightweight yet durable SI Polymer Extreme with steel mounting tab and insert, this flip-up front and rear sight set mounts quickly to any Picatinny rail. The sights fold flat to minimize snagging and do not use an internal spring, preventing accidental deployment. Optimized to be used together, the set sits slightly taller than standard A2 sights and offers tool-less adjustments—rear windage via a knob and front elevation without tools. The rear sight features a quick sliding dual-aperture for fast target acquisition or precision aiming as conditions demand.
