The Reptilia ROF Riser is a 10mm spacer plate for the Trijicon RMR & SRO, fitting between a Reptilia ROF mount and the red dot to lift the optic clear of tall turrets and large scope bells.
10mm of clearance, 16.3 g of aluminium. The tall plate, for the scopes that need it.
A ROF mount carries the red dot close to the scope on purpose, and on most builds that is exactly right. Fit a scope with a large objective bell or a genuinely tall body, though, and the dot can end up crowded by the scope or fouled by a turret cap. The riser is Reptilia's answer: an add-on plate that raises the optic on the ROF by a measured amount without changing anything else about the mount.
It is machined from billet 7075-T6 aluminium, finished in MIL-STD Type III hardcoat anodising, and adds 16.3 g (0.6 oz). The 10mm plate offsets the optic by roughly 0.4 in — this is the one to reach for when the 2.5mm plate is not enough, typically on a 56mm objective or a scope sitting high in tall rings. Made in the USA.
Fits Trijicon RMR and SRO, plus Holosun HS407, HE407, HS507, HE507 and HE508 series. The riser mounts to a Reptilia ROF mount rather than to a scope ring, so it is not tied to a ring diameter — it works the same on a 30mm, 34mm or 35mm ROF as long as that ROF is cut for the RMR & SRO footprint. It is not a Picatinny riser and it will not fit an Aimpoint Micro or an Aimpoint ACRO ROF, because those mounts use a different bolt pattern. This listing is the 10mm height; the subtler plate is the 2.5mm ROF Riser, which Reptilia make in Black only.
Any Reptilia ROF cut for the Trijicon RMR & SRO footprint. That includes the 12 o'clock 30mm ROF-90, 34mm ROF-90 and 35mm ROF-90, and the 45° 30mm ROF-45 and 34mm ROF-45. Measure the clearance you actually need before choosing a height, because a riser taller than necessary lifts the dot further from the scope's centreline.

Most builds do not. The riser exists for scopes with a large objective bell or tall tactical turrets, where the red dot on the ROF ends up fouled or crowded by the scope body. Fit the ROF first, and add a riser only if you actually have a clearance problem.
It fits any Reptilia ROF cut for the Trijicon RMR and SRO footprint, whatever the ring diameter of that mount — 30mm, 34mm and 35mm ROF mounts all take the same riser. It will not fit an Aimpoint Micro or Aimpoint ACRO ROF, because those use a different bolt pattern.
10mm gives roughly 0.4 in of lift and is the one for a 56mm objective or a scope sitting high in tall rings. The <a href="/products/reptilia-rof-riser-2-5mm-trijicon-rmr-sro">2.5mm riser</a> offsets by 0.1 in and is usually enough just to clear a turret cap. Measure the gap before choosing, because a riser taller than you need raises the dot away from the scope's centreline.
Black and Flat Dark Earth Anodized are both offered at this height, in the same billet 7075-T6 aluminium with the same MIL-STD Type III hardcoat anodising. Pick whichever matches the ROF mount underneath it. Note that the 2.5mm plate is made in Black only.
