The Reptilia ROF-90 34mm optic mount adapter transforms your magnified primary optic setup by adding a dedicated 90-degree mounting point for a close-range red dot. Built for shooters who run a Geissele Super Precision mount or Reptilia AUS mount on their rifle, this adapter lets you keep a Trijicon RMR or compatible pistol optic mounted perpendicular to your scope for lightning-fast transitions without removing your eye from the gun. It's the kind of serious-shooter accessory that bridges the gap between precision long-range glass and point-and-shoot defensive speed.
The engineering here is straightforward and purposeful: the ROF-90 positions your secondary optic close enough to the rifle's centerline to avoid a clunky sight picture, yet with enough clearance that your primary scope's image stays clean. That precision in design means you don't sacrifice your magnified zero or waste time hunting for your backup sight. Whether you're setting up a versatile 300 Blackout rig (where your RMR handles subsonic loads while your primary scope covers supersonic duty), or you just want fast medium-distance capability on demand, this adapter earns its real estate on your receiver.
Machined from billet 7075-T6 aluminum and hard anodized to MIL-STD Type III spec, the ROF-90 is built tough enough for hard use and light enough at 33 grams that it won't throw off your balance. Made in the USA, it's the kind of mount adapter that works quietly in the background until you need it.
| Optic Mount Size | 34mm |
| Material | Billet 7075-T6 aluminum |
| Finish | MIL-STD Type III Class 2 hardcoat anodize, black |
| Weight | 33 grams |
| Mounting Angle | 90° (12:00 position) |
| Made In | USA |
The ROF-90 34mm adapter is designed specifically for use with Geissele Super Precision mounts and Reptilia AUS mounts only. It will not fit other mount platforms.
The adapter accommodates Trijicon RMR and SRO optics, as well as Holosun HS407, HE407, HS507, HE507, and HE508 series red dots. Any other optic mounting interface is not supported.
A perpendicular-mounted backup optic gives you fast access to a non-magnified sight for close-range engagements or target transitions without removing your primary scope. Many shooters also use it to zero a secondary optic for a different load—for example, your RMR for subsonic 300 Blackout while your magnified optic handles supersonic duty.
The ROF-90 is engineered to position the red dot close to the rifle's centerline while maintaining enough clearance that your primary optic's sight picture remains unobstructed. The specific mounting geometry minimizes optical interference.
