The Reptilia ROF-45 is a 90° offset mount that transforms your Geissele 30mm Super Precision scope mount into a dual-optic platform. If you run magnified glass for distance work but want a fast, close-range dot ready to deploy without dismounting, this aluminum mount gives you exactly that: a dedicated hard point for a Trijicon RMR positioned to stay out of your scope's sight picture while keeping the secondary optic as close to the primary's centerline as practical. It's a clean, purpose-built solution for shooters who want both reach and speed on the same gun.
The ROF-45 is engineered to minimize parallax and interference between optics. Rather than jury-rigging a tandem setup with compromised ergonomics or sight lines, you get a precision aluminum casting designed specifically for the Geissele platform and optimized around Trijicon's RMR footprint. Drop it onto your existing Geissele mount, secure your RMR, and you're running a cohesive two-optic system without modification to your rifle or scope base.
Compatibility extends beyond the RMR. The ROF-45 also accepts Holosun Technologies' HS407, HE407, HS507, HE507, and HE508 series emitter-based sights, giving you flexibility in which red dot you pair with your magnified scope. That's useful if you already own one of those platforms or want to spec the exact glass that suits your shooting discipline.

Yes — the ROF-45 is specifically designed as a drop-in upgrade for Geissele Automatics' 30mm Super Precision optic mount. No modifications to your rifle, base, or existing scope mounting are necessary.
The ROF-45 accepts Trijicon RMR optics as well as Holosun Technologies' HS407, HE407, HS507, HE507, and HE508 series emitter-based sights. Confirm your specific model matches one of these before ordering.
No — the ROF-45 is engineered to position the offset optic close enough to your scope's centerline to minimize distance while maintaining adequate clearance so the red dot doesn't obstruct your magnified reticle.
The ROF-45 is a drop-in mount for your existing Geissele Super Precision base. Once mounted to your Geissele platform, you simply attach your chosen red dot sight following that optic's standard installation instructions.
