Geissele Super Precision ACOG Desert Dirt Scope Mount for Trijicon 4x ACOG Optics 05-403S was made to fit Trijicon's 4x ACOG scope. This mount is machined from a single piece of 7075-T6 aluminum and given Geissele's exclusive Type III hardcoat Desert Dirt Color finish. This Geissele Super Precision ACOG mount attaches to the rail with 2,800 pounds of clamping force and features 4 shear lugs for maximum rigidity. That clamping force is considerably higher than what a standard ACOG mount delivers, and it matters more than people expect once an optic has been on and off a rifle a few dozen times. Repeated removal is usually where a weaker mount starts losing its return to zero, and this one is built specifically to avoid that. This Geissele ACOG mount for Trijicon 4X ACOG interfaces directly with any Picatinny-style rail. At just 0.375" tall and roughly 3 ounces, it adds almost no height or weight over the rail itself, keeping the ACOG's sight picture close to where Trijicon originally designed it to sit. The low-profile height also means it won't crowd a co-witnessed backup iron sight, which is a common complaint with bulkier aftermarket ACOG mounts.
