The Reptilia ROF-90 is a drop-in upgrade for magnified scope mounts that enhances versatility by adding a dedicated mounting point for a Trijicon RMR, designed to work with the Reptilia AUS Mount or Geissele Super Precision 30mm optic mounts to deliver a fast, close-range optic option without sacrificing the integrity of your magnified sight picture. Crafted from 7075-T6 aluminum and finished in hardcoat anodized, the ROF-90 minimizes the distance between the RMR and the host scopes centerline while maintaining sufficient clearance to prevent the sight picture from being obscured during rapid target acquisition. This thoughtful geometry ensures a clean, single-image co-witness or immediate secondary aiming solution, ideal for dynamic shooting scenarios where quick transitions between magnified and non-magnified optics matter. Compatible with Holosun Technologies HS407, HE407, HS507, HE507, and HE508 series, the ROF-90 integrates smoothly into a Picatinny rail system, offering a reliable, stiff mounting platform for a secondary red dot alongside your primary optic. Built for durability and precision, this Reptilia accessory is an excellent upgrade for serious shooters seeking faster target engagement without compromising optical performance.
