The Fast AEMS positions Holosun AEMS optics precisely at a 2.26 inches optical centerline from the rail. It includes a standard two-cross bolt rail clamp and offers compatibility with the Fast QD (quick detach) Lever for effortless attachment and detachment. This mount seamlessly integrates with any Fast FTC (flip-to-center) magnifier mount for enhanced versatility. Fast optic mounts are part of a series engineered to improve sight picture acquisition speed compared to standard height mounts. By establishing a 2.26 inches optical centerline from the rail, they promote a more ergonomic heads-up posture, facilitating quicker dot/reticle acquisition. This ergonomic advantage is particularly beneficial when using night vision goggles, protective masks, plate carriers and other tactical gear.
