Geissele Automatics Aimpoint Compm5S Optic Mount Absolute Co-Witness Black

The Geissele Automatics Aimpoint CompM5s optic mount in absolute co-witness height brings the precision and durability Geissele is known for to your red dot setup. This mount is engineered specifically for the Aimpoint CompM5s and other red dots with matching footprints, delivering the rock-solid platform you need whether you're running a patrol rifle, competition gun, or dedicated hunting platform. Built from 7075-T6 aluminum and finished in Type 3 Hardcoat anodize, this is a mount that'll weather hard use without compromise.

What sets this mount apart is the attention to engineering detail. Geissele machines it from a single piece of billet aluminum, which means fewer potential weak points and better inherent rigidity than multi-part designs. The mounting system uses a refined nut-and-bolt approach with 1,400 pounds of clamping force—plenty to keep your optic locked down through recoil and rough handling. Three shear lugs add structural stiffness and help ensure your red dot returns to zero shot after shot, year after year. At just 2.1 ounces, the absolute co-witness height keeps weight minimal while giving you iron sight backup if your battery fails or your optic takes damage.

The absolute co-witness height means your iron sights will align perfectly with your CompM5s dot, letting you use traditional backup iron sights without modification or compromise. If you prefer a higher sight picture for better cheek weld and faster target acquisition on an AR-15 platform, Geissele also offers a 1.93-inch height option—but this version puts your sights where they belong for a true co-witness setup.
