Reptilia ROF-90 for Geissele 34mm Super Precision Mounts & Aimpoint ACRO Type III Hardcoat Anodized FDE Anodized. The ROF-90 adds a mounting point at 90 (12:00) for an AIMPOINT Micro (T1-T2-CompM5) to provide for quick transition to a non-magnified optic for close-range target engagement. Additionally the Micro can be zeroed for use with use with subsonic cartridges such as 300 AAC Blackout while allocating the magnified optic for use with supersonic ammunition. Each ROF model is designed to minimize each optics distance from the host scopes centerline while ensuring enough clearance that the sight picture isn't obscured."
