Reptilia · DOT · Lower 1/3
39 mm mount for Aimpoint Micro footprint
Direct Picatinny mount for compatible red dot sights with Aimpoint Micro interface. The 39 mm / Lower 1/3 geometry is a deliberate ergonomic choice, not a universal standard height.

Fits well / fits rather not


Fits well For compatible Aimpoint Micro footprints on M1913 Picatinny when a Lower 1/3 sight line and a fixed, compact direct mount are desired.


Fits rather not For ACRO/MPS, MRO or other footprints, other rail standards, or setups where a significantly lower or higher optic line is deliberately needed.


Practical effect


39 mm / Lower 1/3 The height affects head position and relation to backup sights. It should fit the overall setup and not be chosen isolated by a single number.


Direct footprint A suitable direct mount keeps the number of additional adapters low. Fewer intermediate layers mean a clearer setup.


7075-T6 aluminium The design is aimed at a robust, solid mount, without implying fit for an unconfirmed optic.


Black or FDE The two colour variants do not change the function. Decisive for purchase remain footprint, base, and height.


Limits, disadvantages & avoiding bad purchases

Check footprint first. “Aimpoint & Co” does not mean every red dot sight fits mechanically. The decisive factor is the specific Aimpoint Micro-compatible mount.
Even 39 mm should only be evaluated in context with the optic and platform. After mounting, unload the firearm safely, follow manufacturer instructions, and check point of impact; if unsure, have it mounted professionally.

FAQ
Does the mount fit Aimpoint ACRO or Steiner MPS? No, this product page is for the Aimpoint-Micro interface. There is a separate variant for ACRO/MPS. What does Lower 1/3 mean? It describes the intended optic height relative to the setup. Whether it is ergonomic depends on the platform, optic, and desired head position. Are Black and FDE technically different? Shopify data lists both as colour variants of the same product family. The functional choice remains unchanged. Should it be rechecked after changing the mount? Yes. After any change to the optic mount, seating and point of impact should be securely checked.
Black-Raptor classification: A very clear buy if three things are certain: Aimpoint-Micro footprint, M1913 Picatinny, and exactly the desired Lower-1/3 / 39 mm height. If any of these points are unclear, clarify first, then order.
