The Patented Arisaka Aimpoint Acro Mount Mk2 is expertly designed for the Aimpoint Acro P1 and P2 optics and it's also compatible with other red-dots that share the same footprint, such as the Steiner MPS. This versatile mount is available in three height options: 1.54 inches, 1.93 inches and 2.26 inches. The 1.54 inches version provides a lower 1/3 co-witness, allowing standard AR-height iron sights to be visible in the lower third of the red-dot optic lens, ensuring a seamless sight alignment. The 2.26 inches version is specifically designed to work with the Unity FAST FTC Magnifier Mount, where AR-height iron sights are visible through the window beneath the optic. No matter the height choice, the Arisaka Aimpoint Acro Mount Mk2 offers a reliable and customizable mounting solution to suit your optic and tactical needs.
