The Reptilia DOT Mount is a one-piece Picatinny optic mount for the Aimpoint Micro, holding the optic at Reptilia's 39mm lower 1/3 height, which the trade lists as 1.54in bore height.
One footprint, one height. This is the lower 1/3 version cut for the Aimpoint Micro, and nothing on it adjusts — which is exactly why it holds a zero.
Machined from billet 7075 aluminium and finished in Type III hardcoat anodising, the DOT Mount clamps to any M1913 Picatinny rail through a spring-loaded nitrided 4140 steel clamp. The clamp and mounting bolt sit flush with the body, so there is no proud hardware to catch on a sling, a bag or a barricade. It weighs 51 g (1.8 oz) and carries NSN 1005-01-674-6542.
At Reptilia's 39mm height — 1.54in bore height in dealer language — standard AR-15 back-up iron sights appear in the lower third of the optic window. That is the traditional co-witness: the dot sits where a Micro has always sat, and the irons are there without crowding the picture. On a UK straight-pull AR-15, worked by hand and shot deliberately, a mount with nothing to loosen is worth more than a mount with features. Made in the USA.
Why shooters choose the Lower 1/3 DOT Mount for Aimpoint Micro
-
One optic footprint — cut for the Aimpoint Micro T-1, T-2, H-1, H-2 and CompM5, so the optic beds flat and the screws land square
-
39mm / 1.54in bore height — lower 1/3 co-witness with standard AR-15 back-up iron sights
-
Spring-loaded steel clamp — nitrided 4140 steel, sitting flush with the body for an anti-snag profile
-
51 g (1.8 oz) — billet 7075 aluminium, Type III hardcoat anodised
-
Fitting kit included — mounting screws and a hex L-key come in the box
What the Lower 1/3 DOT Mount for Aimpoint Micro fits
Fits the Aimpoint Micro family — T-1, T-2, H-1, H-2 and CompM5 — and mounts to any M1913 Picatinny rail, including the flat-top upper of a UK straight-pull AR-15. Footprint and height are both fixed on this listing: Aimpoint Micro footprint, Reptilia 39mm (1.54in) lower 1/3 height. Neither is adjustable. If you want the taller sightline for a head-up position, a helmet or night vision, the 1.93in DOT Mount for Aimpoint Micro is the same mount at the greater height. An ACRO, MRO, RMR or 509T will not fit this one — those footprints use different screw positions and a different recoil boss.
