Strike Industries Spbus Polymer Backup Sights Black Folding Ar-15

The Strike Industries SPBUS polymer backup sights deliver dependable emergency optics for your AR-15 when your primary sight system goes down. These folding backup sights are built from reinforced polymer, offering a lightweight alternative to metal irons while maintaining the ruggedness needed for duty, competition, or hunting rifles. Whether you're running an optic-first setup or want a redundant aiming option, polymer backup sights strike the balance between weight savings and reliability—and Strike Industries' design is trusted by shooters who demand gear that works without fuss.

The folding design keeps these sights out of your sight picture when not needed, and they stow flat when not in use. For AR-15 shooters building a complete defensive or hunting rifle, including backup iron sights is smart insurance; a mechanical aiming system requires no batteries and functions regardless of how your primary optic fails.

Strike Industries is known for no-nonsense accessories that perform in field conditions. The SPBUS sights are black-finished and designed to co-witness or act as standalone irons depending on your rifle configuration and intended use.

Frequently Asked Questions

Will these backup sights work with my AR-15 optic mount setup?

These sights are designed for AR-15 platforms. Compatibility depends on your specific rail configuration and optic height; confirm mounting clearance with your existing setup before installation.

Are polymer backup sights as durable as metal irons?

Strike Industries uses reinforced polymer that's proven in field use. Polymer sights are lighter and adequate for backup duty; they're a practical trade-off if weight is a concern. They will perform differently under extreme impact than all-metal sights.

Can I use these as my only iron sights?

Yes, these folding backup sights can serve as your primary aiming system if you don't run a dedicated optic—though the term "backup" reflects their typical role in optic-primary setups.
