Burris AR-F3 Mount is a 1-piece flattop riser mount crafted from steel with a matte black finish, engineered for AR platform firearms. Designed for FastFire series and Docter/Noblex footprint optics, this specialized red dot optic mount delivers absolute co-witness height with standard AR-15 iron sights. It integrates protective side wings to guard the optic lens from impacts and features a cross-slot screw clamp system compatible with Picatinny and Weaver rails. The hollowed base compartment conveniently holds a spare CR1632 battery and tools. Safety Note Always ensure the firearm is unloaded before installing or adjusting any optics or bases. Verify proper torque specifications during installation. Improper mounting may affect accuracy and safety.
