The 34mm ROF-SAR is a drop-in upgrade designed for 34mm optics, adding a mounting point for Trijicon RMR & SRO (and other optics with the same mounting interface). This upgrade enables a seamless transition to a non-magnified optic for close-range engagements. The ROF-SAR allows you to adjust the micro optic's orientation around the magnified optic for optimal positioning. Additionally, the micro optic can be zeroed for subsonic cartridges like .300 AAC Blackout or 8.6 Blackout, while the magnified optic is reserved for supersonic ammunition.
