The Kastle Group ACRO-193™ is a lightweight, precision-machined optic mount designed for Aimpoint® ACRO™ footprint optics. With a 1.93″ optical centerline, the ACRO-193™ provides a higher, more heads-up shooting position while maintaining a compact and lightweight profile for modern rifle configurations.
Built around Kastle Group’s FORTRESS™ mounting system, the ACRO-193™ combines a precision-machined 7075-T651 aluminum body with Kastle’s titanium K-Clamp™ mounting system. The result is a rigid, durable mounting platform designed to securely interface with standard MIL-STD-1913 Picatinny rails without adding unnecessary weight.
The ACRO-193™ is also FORTRESS™ accessory-ready, making it an excellent option for rifles configured around night vision, IR lasers, passive aiming, and other modern weapon accessories.

1.93″ Optical Centerline
The 1.93″ height provides an excellent balance between a traditional optic mount and taller 2.26″ configurations.
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.
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.
Titanium K-Clamp™ Mounting System
Kastle Group’s K-Clamp™ system uses a titanium clamp to provide a secure connection between the mount and Picatinny rail.
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.
Installation requires a T25 Torx bit and a torque wrench capable of 25 in-lbs, with the required mounting hardware included.
Built for Night Vision
The ACRO-193™ is an excellent choice for modern rifles configured around night vision, passive aiming, and IR laser systems.
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.
The FORTRESS™ accessory-ready design also allows compatible Kastle Group accessories to be incorporated into the overall rifle configuration.
Lightweight 7075-T651 Construction
The ACRO-193™ is machined from 7075-T651 aluminum and finished with a Type III MIL-SPEC hardcoat anodized finish.
At just 2.6 oz without the optic, the ACRO-193™ provides a durable mounting platform without adding unnecessary weight to the rifle.
