With increased consumer interest in popular red-dot optics like the Trijicon MRO, Geissele released its 1.93-inch Super Precision Optics Mount designed particularly for this popular red-dot optic available from Trijicon. The unit is machined from one piece of 7075-T6 aluminum and is purpose-built to ensure a solid attachment surface that won’t lose zero once you dial-in your go-to rifle optic.
