The Reptilia ROF-90 is a billet aluminum offset mount that turns your magnified scope setup into a true dual-optic system. Designed specifically for Reptilia AUS Mounts and Geissele 30mm Super Precision optic mounts, the ROF-90 adds a dedicated mounting point for a Trijicon RMR, giving you a fast, close-range aiming solution without sacrificing your primary magnified optic. This is the no-compromise answer for shooters who want both precision capability at distance and lightning-fast acquisition up close.

The engineering here matters: each ROF model is precisely calculated to position your red dot sight as close as possible to your primary scope's centerline while preserving a clear sight picture through the magnified optic. That attention to geometry means you get true co-witnessing and minimal head position shift between optics. Built from 7075-T6 billet aluminum and finished in Mil-Spec Type III hard anodized FDE, the ROF-90 is as durable as it is functional. It weighs just 34 grams—light enough that it won't throw off your balance or add unnecessary mass to your upper receiver.

The ROF-90 is purpose-built for the AR-15 enthusiast or tactical shooter running either a Reptilia or Geissele mount on a precision rifle. Whether you're building a modern sporting rifle, a 3-gun setup, or a tactical carbine that demands both standoff range and close-quarters speed, this mount delivers the modularity and precision fit that separates quality gear from the rest. Made in the USA and engineered by a brand known for no-nonsense optic solutions.

Frequently Asked Questions

Will the ROF-90 work with my current scope mount?

The ROF-90 is compatible only with Reptilia AUS Mounts and Geissele 30mm Super Precision optic mounts. It will not fit other mount types. Confirm your mount before ordering.

What red dot sights can I mount on the ROF-90?

The ROF-90 is designed to accept Trijicon RMR and SRO models, as well as Holosun HS407, HE407, HS507, HE507, and HE508 series optics.

How much does the ROF-90 add to my rifle's weight?

The mount itself weighs 34 grams, so the impact on your rifle's overall weight depends on which red dot you mount to it. The ROF-90 is designed to be a minimal-mass solution.

Can I use the ROF-90 as a standalone red dot mount?

No—the ROF-90 is an offset accessory mount that works in conjunction with Reptilia AUS or Geissele Super Precision 30mm mounts. It is not a primary optic mount and requires a compatible base mount installed on your rifle first.
