Reptilla LLC ROF-90 Mount, Compatible w/ Geissele 34mm Super Precision & Trijicon RMR, FDE Anodized

The Reptilia ROF-90 is a 34mm offset optic mount designed to add a secondary aiming solution to precision rifle setups. If you're running a magnified scope on a Reptilia AUS or Geissele Super Precision mount, the ROF-90 clamps a red-dot sight—Trijicon RMR, SRO, or compatible optics from Holosun—at 90 degrees for quick close-range transitions without removing your hand from the gun. This is the setup that serious rifle builders choose when they want both magnified and non-magnified sight options on a single platform.

The tactical advantage is real: zero your dot for subsonic ammunition while keeping your primary scope dialed for supersonic rounds, then toggle between them based on your load or engagement distance. The mount's engineering minimizes the offset distance from your scope's optical axis, so your secondary sight picture stays clean and unobstructed. Built from billet 7075-T6 aluminum and finished in flat dark earth hard anodize, it's light at 33 grams and tough enough for professional and competitive use.

Reptilia engineered this mount specifically for compatibility with the Geissele Super Precision and their own AUS platform—it's a drop-in upgrade if you already own one of those bases. Manufactured in the USA and finished to military-spec standards, the ROF-90 is the kind of component serious shooters trust on rifles that see real use, whether that's precision hunting, tactical training, or the range.

Frequently Asked Questions

What mounts is the ROF-90 compatible with?

The ROF-90 is designed as a drop-in upgrade for the Reptilia AUS Mount and the Geissele Super Precision mount. It will not fit other 34mm mounting systems.

Which red-dot sights can I use with this mount?

The ROF-90 is compatible with the Trijicon RMR and SRO, and with Holosun HS407, HE407, HS507, HE507, and HE508 series optics.

Why would I want a 90-degree offset mount on my scope?

A secondary red-dot at 90 degrees lets you keep a magnified scope for distance shooting and quickly acquire a close-range target with an unmagnified sight without removing your hand or shifting your cheek weld. Many shooters also zero their red-dot for subsonic ammunition and their primary scope for supersonic rounds, giving them flexibility across different load choices.

Is this mount made in the US?

Yes, the ROF-90 is manufactured in the USA from billet aluminum and finished to military hard-anodize standards.
