The Fast MicroPrism positions Primary Arms MicroPrism optics and other industry-standard mini-prism optics at a 2.26 inches optical centerline from the rail. It features a standard two-cross bolt rail clamp and is compatible with the Fast QD (quick detach) Lever for swift installation and removal. Fast optic mounts enhance operational efficiency by providing a quicker sight picture compared to standard height mounts. By establishing a 2.26 inches optical centerline from the rail, they promote ergonomic heads-up posture for rapid visual processing on the battlefield. This configuration facilitates faster dot/reticle acquisition, even when using night vision goggles, protective masks, plate carriers and other equipment.
