The Reptilia DOT Mount is a one-piece Picatinny optic mount for the Trijicon MRO, placing the optical axis 1.93in (49 mm) above the rail.
The lightest mount in Reptilia's 1.93in DOT range at 45 g, cut for one optic and set at one height.
Reptilia machine the 1.93in MRO mount from billet 7075-T6 aluminium and finish it in Milspec Type III hard anodising. It attaches to any M1913 Picatinny rail and carries a nitrided 4140 steel clamp, with mounting screws and a hex L-key in the box.
The MRO's wide 25 mm objective is one of the easier red dots to pick up quickly, and at 1.93in it sits where your eye already is with your head upright. On a UK straight-pull AR-15 that means the same head position on every mount of the rifle, which is what makes a fast first shot repeatable rather than lucky. Made in the USA.
Fits the Trijicon MRO, on any M1913 Picatinny rail including the flat-top upper of a UK straight-pull AR-15. Footprint and height are both fixed: MRO footprint, 1.93in optical axis. Standard AR-15 back-up iron sights do not co-witness at this height — for that, Reptilia make a 39mm lower 1/3 MRO DOT Mount. An Aimpoint Micro or ACRO uses a different footprint and will not fit this mount.

£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.
Reptilia list this mount for the Trijicon MRO. The MRO family shares one mounting interface across the range, but if you are running a specific variant it is worth checking the base of your optic against Trijicon's own specification before ordering, because a mount cut for one footprint cannot be shimmed to fit another.
The MRO's mounting interface needs less material around it than an ACRO or RMR pattern does, so the same 1.93in height comes out at 45 g rather than 55 to 60 g. It is the same billet 7075-T6 aluminium and the same clamp design; there is simply less of it.
At 1.93in, standard AR-15 back-up iron sights fall below the optic window, so they will not appear as a co-witness. If you want them in view, the <a href="/products/reptilia-dot-mount-trijicon-mro-lower-1-3">39mm lower 1/3 MRO mount</a> is the version that gives you that. The two are separate products and neither converts into the other.
Reptilia do not publish a torque figure for the DOT Mount, so we will not invent one. Fit it firmly with the supplied hex L-key, confirm the mount does not move on the rail by hand, and check your zero after the first range session as you would with any Picatinny mount that has just gone on.
