Strike Industries Polymer Backup Sights

Upgrade your AR platform with the Strike Industries Polymer Backup Sights (SPBUS), a lightweight and durable flip-up sight system engineered for reliable performance when it matters most. Designed for rifles equipped with a standard Picatinny rail, these low-profile iron sights provide fast target acquisition, dependable backup aiming capability, and compact storage when not in use. Unlike traditional flip-up sights, the SPBUS features integrated emergency sight channels that remain usable even when the sights are folded down, giving shooters an added layer of redundancy.

Constructed from Strike Industries’ proprietary SI Polymer Extreme material with reinforced steel mounting components, the Srike Polymer Backup Sights delivers an ideal balance of strength, durability, and weight savings. The manual deployment design prevents accidental activation, while the low-snag profile helps minimize interference with slings, gear, and accessories. Tool-free windage and elevation adjustments allow for quick zeroing in the field, and the dual-aperture rear sight offers both rapid close-range engagement and enhanced precision at longer distances.

Whether used as a primary sighting system or as a backup to a red dot or LPVO, the Strike Industries SPBUS provides dependable performance without adding unnecessary bulk. Affordable, lightweight, and easy to install, these polymer backup sights are an excellent choice for AR-15 owners seeking a versatile and reliable iron sight solution.
