Kastle Group ACRO-45™ Offset Mount

The Kastle Group ACRO-45™ is a lightweight 45-degree offset optic mount designed specifically for Aimpoint® ACRO™ footprint red dot sights. Built for shooters who need a fast-access secondary aiming solution, the ACRO-45™ allows users to quickly transition between a primary optic and a backup red dot without adding unnecessary bulk or complexity to their rifle system.

Designed as part of Kastle Group’s FORTRESS™ mounting ecosystem, the ACRO-45™ provides a seamless integration with compatible Kastle optic mounts, creating a streamlined and rugged solution for modern duty rifles, competition builds, and night vision-focused platforms.

The 45-degree offset configuration allows shooters to rotate the rifle and immediately access their secondary optic while maintaining their primary optic setup. This provides an effective solution for close-range engagements, rapid target transitions, and situations where a magnified optic or primary sighting system may not be ideal.

For night vision users, the ACRO-45™ provides an excellent passive aiming option when paired with helmet-mounted night vision goggles. A dedicated offset red dot allows shooters to maintain a heads-up shooting position while providing a reliable aiming reference in low-light environments without relying solely on an IR laser.

Machined from 7075 aluminum and finished with a Type III hardcoat anodizing, the ACRO-45™ is built for durability while maintaining a lightweight profile. Its compact design minimizes snag points and keeps the rifle balanced during dynamic shooting applications.
