Trijicon SRO pattern

The RMR footprint – which Trijicon SRO uses – consists of two sockets in the front corners of the front of the sight and of two screw holes in the center of the sight.

The front socketes are 22,5mm / 0.89 inches far from each other. Position of these two sockets corresponds to position of pins that are on a mounting surface of any mount for this standard.

The screw holes are positioned in the rear part of the optic device. These function for fixation of the sight to the mounts. These two screw holes are 18,8mm / 0.74 inches far from each other.

The distance between the front sockets and rear screw holes is 22,3mm / 0.88 inches.

The screws that are to be used for these screw holes are always included in the package with the sight.
