While optics like the Aimpoint® CompM5s, CompM5b, and Duty RDS share similar mounting patterns, their lower battery compartments or raised base geometries make them taller than standard Aimpoint® Micro (T1/T2/CompM5) red dots. Mounting these "taller" micro sights on standard micro mounts results in an excessively high optic centerline, misaligning the sight picture with auxiliary magnifiers and night vision optics. The Unity Tactical FAST™ Micro-S is specifically engineered to bridge this geometric gap. By lowering the mounting platform height, the FAST™ Micro-S places the Aimpoint® CompM5s, CompM5b, and Duty RDS precisely at the established 2.26″ optical centerline. This ensures an ergonomic, upright heads-up shooting posture for rapid visual acquisition and effortless passive aiming under night vision. Crucially, it provides 100% full compatibility across the entire line of FAST™ FTC magnifier mounts. CNC-machined from 7075-T6 aerospace aluminum, the FAST™ Micro-S weighs under 2.5 oz, comes standard with a two cross-bolt rail clamp, and accepts the optional FAST™ QD Lever. Key Features Tailored Height Geometry: Specifically designed for taller micro red dots (CompM5s, CompM5b, Duty RDS) to maintain precise optical baseline parameters. 2.26″ Optical Centerline Height: Elevates your sight line to 2.26" for improved visual processing speed, comfortable posture, and seamless NVG passive aiming. Full FTC Magnifier Compatibility: Integrates flawlessly with all Unity FAST™ FTC (Flip-to-Center) magnifier mounts for unified optical axis alignment. Ultra-Lightweight 7075-T6 Aluminum: Machined from high-strength 7075-T6 aluminum with Type III hardcoat anodizing, weighing less than 2.5 oz (70.9 g). Modular Rail Clamp System: Features a heavy-duty two cross-bolt clamp interface and supports retrofitting with the FAST™ QD Lever.
