The Arisaka Aimpoint Acro Mount Mk2 (brand part no. OM2-ACRO-154) is a patented red dot mount designed for the Aimpoint Acro P1 and P2, and it also functions with other optics sharing that footprint, like the Steiner MPS. This 1.54-inch version sets the enclosed-emitter optic at a lower 1/3 co-witness height, so standard AR-height iron sights show through the bottom third of the lens for a fast, layered backup sighting setup. Finished in black, it is a strong option for shooters running an Acro or MPS red dot who still want iron sights in the picture.

Frequently Asked Questions

What co-witness does the 1.54-inch height give me? It provides a lower 1/3 co-witness, meaning your iron sights appear in the lower third of the optic’s lens.

Will this fit a Steiner MPS? Yes, it fits any enclosed-emitter red dot sharing the Aimpoint Acro footprint, including the Steiner MPS.

Is this the same mount as the Arisaka Micro version? No, this Acro Mount Mk2 is cut for the Aimpoint Acro/Steiner MPS footprint; Arisaka sells a separate Micro Mount Mk2 for the Aimpoint Micro footprint.
