The ROF-90 puts the red dot directly above the scope at 90°, where your eye already is.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReptilia call 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 centreline, so moving between magnified and unmagnified is a change of focus rather than a change of position.\u003c\/p\u003e\u003cp\u003eIt is machined from billet 7075-T6 aluminium and finished in MIL-STD Type III hardcoat anodising, at 33 g (1.2 oz). On a UK straight-pull AR-15 or a precision bolt gun 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.

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, Trijicon RMR \u0026amp; SRO footprint. Neither is adjustable, so check both against your own mount and optic before ordering.\u003c\/p\u003e\u003ch3\u003eHow the ROF-90, ROF-45 and ROF-SAR differ\u003c\/h3\u003e\u003cp\u003eReptilia build three mounts on this footprint and this ring diameter, and they are three different mechanisms. The ROF-90 on this page piggybacks the red dot at 12 o'clock on top of the scope-ring cap. The \u003ca href=\"\/products\/reptilia-rof-45-34mm-trijicon-rmr-sro\"\u003e34mm ROF-45\u003c\/a\u003e holds the same optic at 45°, so you roll the rifle rather than shift focus. The \u003ca href=\"\/products\/reptilia-rof-sar-34mm-trijicon-rmr-sro\"\u003e34mm ROF-SAR\u003c\/a\u003e replaces the ring cap entirely instead of sitting on top of it, which carries the dot lower over the bore. All three accept the same optic, so the choice is where you want the dot rather than what will fit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eTrijicon RMR and SRO, plus Holosun HS407, HE407, HS507, HE507 and HE508 series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eRing-cap red dot mount, 90° (12 o'clock)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eBillet 7075-T6 aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eMIL-STD Type III hardcoat anodised — Black, Flat Dark Earth Anodized\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e33 g (1.2 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount interface\u003c\/th\u003e\n\u003ctd\u003e34mm Reptilia AUS or Geissele Super Precision scope-ring cap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMade in\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eReptilia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003e100-018 · 100-029\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eSame rifle, two sight pictures. \u003cstrong\u003eOrder the 34mm ROF-90 today\u003c\/strong\u003e — in stock at Xtreme Tactical Gun Parts with free tracked UK delivery in 7–10 days.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExplore more:\u003c\/strong\u003e \u003ca href=\"\/collections\/ar-15-parts-accessories\"\u003eAR-15 Parts \u0026amp; Accessories\u003c\/a\u003e or browse all \u003ca href=\"\/collections\/reptilia\"\u003eReptilia\u003c\/a\u003e.\u003c\/p\u003e","brand":"Reptilia","offers":[{"title":"Black","offer_id":42843573190736,"sku":"100-018","price":139.99,"currency_code":"GBP","in_stock":false},{"title":"Flat Dark Earth Anodized","offer_id":42843573223504,"sku":"100-029","price":139.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0550\/4978\/1328\/files\/reptilia-rof-90-34mm-trijicon-rmr-sro-black.jpg?v=1786511615","url":"https:\/\/xtremetacticalgunparts.co.uk\/products\/reptilia-rof-90-34mm-trijicon-rmr-sro","provider":"Xtreme Tactical Gun Parts","version":"1.0","type":"link"}
