The Fast AEMS positions Holosun AEMS optics at a 2.26 inches optical centerline from the rail. It features a standard two-cross bolt rail clamp and is also compatible with the Fast QD (quick detach) Lever for convenient attachment and detachment. This mount can be combined with any Fast FTC (flip-to-center) magnifier mount. Fast optic mounts are part of a series designed to enhance 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 advantage is particularly valuable when using night vision goggles, protective masks, plate carriers and other tactical equipment.
