Description
Strike Industries SPBUS Polymer Backup Sights are folding back up sights for the AR-15 platform. They use lightweight SI Polymer Extreme with a steel mounting tab and insert. When flipped down, both sights sit low for clearance. The SPBUS rear sight has an adjustment knob for windage, and the front sight elevation is adjustable without tools. The rear features dual apertures for different eye relief needs, with no internal spring to prevent accidental deployment.
