The Reptilia ROF-90 35mm RMR mount is a dedicated offset optic adapter designed to bring rapid-acquisition red-dot capability to tactical rifle builds. Built as a drop-in upgrade for Reptilia AUS mounts and Geissele Super Precision mounts, this 90-degree top-rail solution lets you run a Trijicon RMR in true co-witness orientation without sacrificing your primary optic. Whether you're setting up a duty rifle, competition gun, or precision platform that demands fast transitions to close targets, the ROF-90 gives you a secondary aiming solution mounted at 12 o'clock where it belongs—fast to acquire, intuitive to shoot.
Reptilia machines the ROF-90 from 7075-T6 billet aluminum, the same aerospace-grade stuff that keeps other precision components lightweight and rigid. The hardcoat anodize meets military specifications (MIL-STD Type III), which means it'll handle field use, storage, and the occasional hard knock without losing its finish or zero. The clean, minimal design doesn't add unnecessary weight or bulk, and the engineering is straightforward: install it on a compatible mount, attach your RMR, and get to work.
If your optics setup relies on a Reptilia AUS or Geissele Super Precision mount, the ROF-90 is the proven way to add a non-magnified offset without cobbling together incompatible adapters. It's a solid choice for shooters who want genuinely useful backup or close-range capability built into a rigid, repeatable system.
