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 30mm 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 30mm 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.
It is machined from billet 7075-T6 aluminium and finished in MIL-STD Type III hardcoat anodising, at 30 g (1.1 oz). On a UK straight-pull AR-15 that 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.
Fits the Aimpoint ACRO P1, P2 and C2, and the Steiner Optics MPS. The ROF-90 is a drop-in upgrade for 30mm Reptilia AUS mounts and 30mm 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: 30mm rings, ACRO and MPS footprint. Neither is adjustable, so check both against your own mount and optic before ordering.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.
You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging. Faulty, damaged or incorrect items are replaced or refunded and we cover reasonable return postage. Refunds go back to your original payment method within 14 days of receiving the return.
Only if you are running a 30mm Reptilia AUS mount or a 30mm 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 30mm ring of another make or any other ring diameter. Check your mount's specification before ordering.
The Aimpoint ACRO P1, P2 and C2, and the Steiner Optics MPS. That is one footprint family, and an optic from another family will not sit on it — the screw positions and the recoil boss differ.
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. A 45-degree offset asks you to roll the rifle instead. If you want an offset ACRO on a Picatinny rail rather than on a scope mount, see the <a href="/products/reptilia-dot-mount-offset-aimpoint-acro-steiner-mps">Offset DOT Mount</a>.
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. Confirm both zeros after fitting, as you would with any mount that has come off and gone back on.
