Upgrade your rifle with the FAB Defense FBS Front Backup Sight for AR15. This advanced, low-profile sight is designed for durability and precision. Whether you’re using it as a primary or secondary sight, it enhances your shooting accuracy. It’s compatible with all 1913 Picatinny rails, making it ideal for M4, AR-15, and M-16 platforms. For the ultimate optical advantage, pair it with the FAB Defense® RBS Rear Back-up Sight. Together, they create a precise optical tunnel for faster target acquisition. The FBS sight’s elevation can be adjusted quickly without tools, saving you time in critical moments.
Crafted from high-grade polymer and metal, it offers exceptional strength and reliability. The ergonomic design includes an angel-wing-shaped front shroud, which helps center your aim. Its low folded profile prevents snagging on gear, webbing, or brush. The instant spring-locked deployment system ensures it won’t slip, break, or deform under pressure. Available in black, olive drab green, and desert tan, this sight blends seamlessly with your rifle.
