The Reptilia ROF-90 is a 12 o'clock red dot mount for the Aimpoint Micro, machined as a drop-in upgrade for 35mm Reptilia AUS and Geissele Super Precision scope mounts.
One ring diameter, one optic footprint. The ROF-90 puts the red dot directly above the scope at 90°, where your eye already is.
Reptilia calls it Ring Optic Forward. The ROF-90 sits on the scope-ring cap of a 35mm mount and carries a miniature red dot at the 12 o'clock position rather than hanging it off a separate rail or an offset bracket. That keeps the dot close to the scope's centerline, so moving between magnified and unmagnified is a change of focus rather than a change of position.
It is machined from billet 7075-T6 aluminum and finished in MIL-STD Type III hardcoat anodizing. Reptilia does not publish a weight for the 35mm version, so we are not quoting one. On an AR-15 the ROF-90 earns its keep at the awkward end of the range card: the scope stays set for the shot you planned, the dot takes the one that appears at 25 m, and each keeps its own zero. Made in the USA.
Key Features
- 90° mounting point: The dot sits at 12 o'clock directly above the scope, not offset to one side
- Drop-in upgrade: Fits 35mm Reptilia AUS and Geissele Super Precision mounts, with no extra rail or riser
- Billet 7075-T6 aluminum: MIL-STD Type III hardcoat anodized in Black or Flat Dark Earth Anodized
- One footprint: Cut for the Aimpoint Micro and nothing else, so the optic beds flat and the screws land square
- Independent zero: The red dot keeps a close-range zero while the scope keeps yours
Compatibility & Fitment
Fits Aimpoint Micro R-1, H-1, H-2, T-1, T-2 and CompM5, Sig Sauer ROMEO4, ROMEO5 and ROMEO-MSR, Vortex Crossfire, Spitfire and Sparc I & II, Primary Arms Classic Series Gen II, SLx Advanced Rotary Knob Microdot and SLx Compact 1x20 Prism Scope, and Holosun HS403 (not HS403A), HE403, HS503, HE503, HS515, HE515 and HE530. The ROF-90 is a drop-in upgrade for 35mm Reptilia AUS mounts and 35mm Geissele Super Precision mounts only — it is not a Picatinny mount, and it will not fit a scope ring of any other diameter. Ring diameter and optic footprint are both fixed on this listing: 35mm rings, Aimpoint Micro footprint. Neither is adjustable, so check both against your own mount and optic before ordering.

Frequently Asked Questions
Will the ROF-90 fit my mount?
Only if you are running a 35mm Reptilia AUS mount or a 35mm Geissele Super Precision mount. The ROF-90 sits on the ring cap of those mounts, so it is not a Picatinny mount and it will not fit a 35mm ring of another make or any other ring diameter. Check your mount's specification before ordering.
Which optics does it take?
One footprint only — the Aimpoint Micro family, with the full list in the specifications above. A mount cut for another footprint will not accept your optic, because the screw positions and the recoil boss differ between them.
What does it weigh?
Reptilia does not publish a weight for the 35mm ROF-90, so we have not quoted one. For reference they publish 25 g for the 30mm version and 27 g for the 34mm, and all three are machined from the same billet 7075-T6 aluminum.
Does the red dot share the scope's zero?
No, and that is the point. The dot is zeroed on its own for close range while the scope keeps the zero you set for distance, so you are not re-dialing between the two. Confirm both zeros after fitting, as you would with any mount that has come off and gone back on.
