Overview
This mount is built for pairing the Trijicon Miniature Rifle Optic with a lower 1/3 co-witness setup, making it a practical choice for shooters who want a streamlined optic position on a compatible rifle. Its quick-detach lever system is intended to work with both in-spec and out-of-spec rail systems, which adds flexibility when moving the optic between platforms. Precision-machined from 6061 T6 aluminum and finished with a hard coat T3 Mil-Spec anodize, it is a purpose-driven mounting solution from American Defense Manufacturing. The extended thumb pad on the tactical lever is a useful touch for fast attachment and removal in the field or at the range.

Considerations & Trade-offs
- This mount is configured for a Lower 1/3rd co-witness setup, so it may not match shooters who prefer a different optic height or sight picture.
- The quick-detach lever system is built to work with both in-spec and out-of-spec rail systems, but that flexibility can be more than needed if the rifle is already set up around a fixed mount.
- It is finished in Flat Dark Earth, which is useful for color-matching but may not suit every rifle or optic combination.
- The design is specific to the Trijicon Miniature Rifle Optic, so compatibility is narrower than a more universal mount.
