The Unity Tactical MRDS 30mm Top Ring functions as a specialized piggyback expansion cap designed to add a secondary reflex sight straight over a primary low-power variable optic setup. Machined from robust 7075-T6 aluminum and finished in a Type III hardcoat black anodizing, this component directly swaps out with the existing factory top half ring on a 30mm FAST REKE mount. By shifting the backup red dot to the 12 o'clock position, it provides an ambidextrous close-quarters aiming point that completely eliminates the asymmetrical left-or-right view biases found on traditional 45-degree offset brackets. This elevated secondary profile yields a clear viewing plane that easily bridges over large tactical scope adjustment turrets without adding wide gear-snag hazards to the sides of the weapon receiver. Engineered as a foundational block of the modular FAST accessory suite, this block accepts a variety of footprint plates to securely host micro sights from brands like Aimpoint, Trijicon, Leupold, and Holosun.
