The Reptilia ROF-90 is a 12 o'clock red dot mount for the Aimpoint ACRO and Steiner MPS, machined as a drop-in upgrade for 34mm 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 34mm 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.
Billet 7075-T6 aluminum, MIL-STD Type III hardcoat anodized, 1.2 oz (35 g). On an AR-15 it 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 34mm Reptilia AUS and Geissele Super Precision mounts, with no extra rail
- Billet 7075-T6 aluminum: Hardcoat anodized, 1.2 oz (35 g) on the rifle
- One footprint: Cut for the Aimpoint ACRO and Steiner MPS and nothing else
- Independent zero: The red dot keeps a close-range zero while the scope keeps yours
Compatibility & Fitment
Fits the Aimpoint ACRO P1, P2 and C2, and the Steiner Optics MPS. The ROF-90 is a drop-in upgrade for 34mm Reptilia AUS mounts and 34mm 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: 34mm rings, ACRO and MPS footprint. Neither is adjustable, so check both before ordering.

Frequently Asked Questions
Will the ROF-90 fit my mount?
Only if you are running a 34mm Reptilia AUS mount or a 34mm Geissele Super Precision mount. It sits on the ring cap of those mounts, so it is not a Picatinny mount and it will not fit any other ring diameter.
Which optics does it take?
The Aimpoint ACRO P1, P2 and C2, and the Steiner Optics MPS. An optic from another footprint family will not sit on it.
Why 12 o'clock rather than 45 degrees?
At 90 degrees the dot sits directly above the scope, so the transition is a change of focus and the rifle stays where it is. If you want an offset ACRO on a Picatinny rail instead, see the Offset DOT Mount.
