The Unity Tactical MRDS Top Ring for FAST REKE 34mm integrates directly into weapon setups utilizing a standard 1.54-inch optical centerline height. This replacement hardware is meticulously bored to clamp securely onto large tactical scope main tubes measuring exactly 34 millimeters in diameter. By replacing a factory upper ring cap, it establishes an elevated mounting deck centered over the rifle bore to support secondary backup sights. This twelve o'clock alignment allows marksmen to quickly raise their line of sight to engage immediate threats without modifying their core shooting stance or weapon zero configuration. Built from rugged 7075-T6 aluminum, the durable assembly provides exceptional zero retention for electronic reflex sights during aggressive tactical maneuvers and heavy rifle recoil.
