The Kastle Group ACRO-193™<\/strong> is a lightweight, precision-machined optic mount designed for Aimpoint\u00ae ACRO™ footprint optics<\/strong>. With a 1.93″ optical centerline<\/strong>, the ACRO-193™ provides a higher, more heads-up shooting position while maintaining a compact and lightweight profile for modern rifle configurations.<\/p>\n

Built around Kastle Group’s FORTRESS™ mounting system<\/strong>, the ACRO-193™ combines a precision-machined 7075-T651 aluminum body<\/strong> with Kastle’s titanium K-Clamp™ mounting system<\/strong>. The result is a rigid, durable mounting platform designed to securely interface with standard MIL-STD-1913 Picatinny rails without adding unnecessary weight.<\/p>\n

The ACRO-193™ is also FORTRESS™ accessory-ready<\/strong>, making it an excellent option for rifles configured around night vision, IR lasers, passive aiming, and other modern weapon accessories.<\/p>\n

    Compatible optics include:<\/p>\n

      \n
    • Aimpoint\u00ae ACRO P-1<\/li>\n
    • Aimpoint\u00ae ACRO P-2<\/li>\n

    • Viridian\u00ae RFX44<\/li>\n<\/ul>\n

      1.93″ Optical Centerline<\/h3>\n

      The 1.93″ height<\/strong> provides an excellent balance between a traditional optic mount and taller 2.26″ configurations.<\/p>\n

      For modern rifle setups, the elevated optical centerline allows the shooter to maintain a more upright head position while providing additional clearance around other equipment. This makes the ACRO-193™ particularly well suited for rifles equipped with night vision and IR aiming systems<\/strong>.<\/p>\n

      The 1.93″ height also provides a clean configuration for shooters who want the advantages of an elevated optic without moving to an extremely tall mount.<\/p>\n

      Titanium K-Clamp™ Mounting System<\/h3>\n

      Kastle Group’s K-Clamp™<\/strong> system uses a titanium clamp to provide a secure connection between the mount and Picatinny rail.<\/p>\n

      The mounting interface is designed around a rigid connection and integrated recoil lug system, helping maintain a secure and repeatable optic position under demanding use.<\/p>\n

      Installation requires a T25 Torx bit and a torque wrench capable of 25 in-lbs<\/strong>, with the required mounting hardware included.<\/p>\n

      Built for Night Vision<\/h3>\n

      The ACRO-193™ is an excellent choice for modern rifles configured around night vision, passive aiming, and IR laser systems<\/strong>.<\/p>\n

      The 1.93″ optical centerline provides additional clearance and allows the shooter to maintain a more natural head position behind the rifle. When paired with helmet-mounted night vision, this elevated optic height can be especially useful for passive aiming configurations.<\/p>\n

      The FORTRESS™ accessory-ready<\/strong> design also allows compatible Kastle Group accessories to be incorporated into the overall rifle configuration.<\/p>\n

      Lightweight 7075-T651 Construction<\/h3>\n

      The ACRO-193™ is machined from 7075-T651 aluminum<\/strong> and finished with a Type III MIL-SPEC hardcoat anodized finish<\/strong>.<\/p>\n

      At just 2.6 oz without the optic<\/strong>, the ACRO-193™ provides a durable mounting platform without adding unnecessary weight to the rifle.<\/p>\n
