The 34mm ROF-SAR is a drop-in upgrade for 34mm optics. The ROF-SAR adds a mounting point for an TRIJICON(R) RMR & SRO (and other optics utilizing the same mounting interface, list below) to provide for quick transition to a non-magnified optic for close-range target engagement. The ROF-SAR allows for user to orient the Micro optic at their desired orientation around the magnified optic. Additionally, the Micro can be zeroed for use with use with subsonic cartridges such as 300 AAC Blackout or 8.6 Blackout, while allocating the magnified optic for use with supersonic ammunition. Compatible with: Trijicon(R) - RMR & SRO Holosun(R) Technologies - HS407, HE407, HS507, HE507, & HE508 Series
