The Arisaka Aimpoint Micro Mount Mk2 (brand part no. OM2-MICRO-193) is a patented red dot mount built for the Aimpoint Micro T1 and T2, and it shares its footprint with the Aimpoint H1/H2, Aimpoint Comp M5/M5S, Sig Romeo 4 and 5, and Holosun HS503/515/530. This 1.93-inch version sets the optic at an absolute co-witness height with standard AR-height iron sights, putting the front and rear sight posts directly in line with the dot. Finished in black, it is a solid choice for duty and competition carbines running a Micro-footprint red dot alongside iron sights.
