The Reptilia ROF-90 is a precision-engineered drop-in upgrade for the Geissele Automatics Super Precision 34mm optic mount, adding a dedicated 12 o'clock mounting position for a Trijicon RMR so you can instantly transition between magnified and unmagnified optics without breaking your shooting rhythm.
- Drop-in compatibility with Geissele Super Precision 34mm optic mounts
- Adds a 90° (12:00) mounting point for a Trijicon RMR red dot
- Enables independent zero for subsonic loads like 300 AAC Blackout
- Minimizes RMR distance from the host scope's centerline for efficiency
- Machined from billet 7075-T6 aluminum for maximum strength and minimal weight
- MIL-STD Type III hardcoat anodized finish for lasting corrosion resistance
Who This Is For
The Reptilia ROF-90 is purpose-built for tactical shooters, competition competitors, and suppressor users who run a magnified optic for long-range precision but need an instant, reliable transition to a red dot for close-quarters engagement. It's especially valuable for 300 AAC Blackout operators who alternate between supersonic and subsonic ammunition, allowing each optic to be independently zeroed for its intended load — all on a single host rifle.

Frequently Asked Questions
Which Geissele mount is the ROF-90 compatible with?
The Reptilia ROF-90 is specifically designed as a drop-in upgrade for the Geissele Automatics Super Precision (SPM) 34mm optic mount. It is not a standalone ring mount — you must already own or purchase a compatible Geissele 34mm Super Precision mount for the ROF-90 to attach to. Always verify your mount's ring diameter before ordering.
Can I zero the RMR independently from my primary scope?
Yes — that's one of the primary advantages of the ROF-90 system. The Trijicon RMR mounted at 12 o'clock can be independently zeroed at a different distance or for a different load than your primary magnified optic. This is particularly useful for 300 AAC Blackout shooters who want the RMR zeroed for subsonic rounds while the main scope is dialed in for supersonic ammunition.
Will the RMR obstruct the sight picture of my primary scope?
Reptilia engineered the ROF-90 to position the RMR as close as possible to the host scope's centerline while maintaining enough clearance that the RMR body does not intrude into the primary optic's field of view. The design prioritizes a clean, unobstructed sight picture through your main scope while keeping the offset red dot immediately accessible for rapid close-range target acquisition.
