Polymer Backup Sights

Package Contents: - 1 x SPBUS front sight (fully assembled) - 1 x SPBUS rear sight (fully assembled) - 1 x Hex tool [2.0mm] - 1 x Loctite Threadlocker Blue 243

The Strike Polymer Backup Sights (SPBUS) are a cost-effective, low-profile sighting system designed for the AR platform. These sights offer built-in backup sights when flipped down, ensuring quick target acquisition without the need to flip up the sights. Made from lightweight and durable SI Polymer Extreme material with a steel mounting tab and insert, the SPBUS sights can withstand heavy use without any issues.

Installation of the SPBUS sights is quick and easy, requiring only a Picatinny rail. Both sights can be flipped down flat to avoid obstructing your view or snagging on gear when not in use. Unlike other sights, the SPBUS does not have an internal spring, preventing accidental deployment when not needed.

These sights are slightly taller than standard A2 sights, optimized for use together rather than paired with other sights. The rear sight features an adjustable knob for windage adjustments, while the front sight can be easily adjusted for elevation without any tools.

The dual aperture rear sight offers flexibility in different shooting conditions, with larger and smaller apertures for longer eye relief or greater accuracy as needed. Users can customize the front sight with their preferred color.

The SPBUS sights are a versatile option for both primary and backup sight use, offering tool-less adjustments and durability at an affordable price point.
