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 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 call 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 centreline, so moving between magnified and unmagnified is a change of focus rather than a change of position.
Billet 7075-T6 aluminium, MIL-STD Type III hardcoat anodised, 35 g (1.2 oz). On a UK straight-pull 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.
Why shooters choose the 35mm ROF-90
-
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
-
Billet 7075-T6 aluminium — hardcoat anodised, 35 g (1.2 oz) 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
What the 35mm ROF-90 fits
Fits the Aimpoint ACRO P1, P2 and C2, and the Steiner Optics MPS. 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, ACRO and MPS footprint. Neither is adjustable, so check both before ordering.
