Kastle Group MICRO-226™ 2.26″ Optic Mount

The Kastle Group MICRO-226™ is a precision-machined red dot optic mount designed around the Aimpoint® MICRO™ footprint and built for shooters who want a higher, more heads-up shooting position. With a 2.26″ optical centerline, the MICRO-226™ provides additional clearance for night vision devices while promoting fast, natural target acquisition. Built as part of Kastle Group’s FORTRESS™ mounting system, the MICRO-226™ combines a lightweight 7075-T651 aluminum body with Kastle’s titanium K-Clamp™ mounting technology. The K-Clamp™ system is designed to provide a secure connection to MIL-STD-1913 Picatinny rails while maintaining a lightweight and highly rigid mounting platform. The MICRO-226™ also incorporates ambidextrous M-LOK™ accessory slots and is FORTRESS™ accessory-ready, allowing additional accessories such as the Kastle DB-226™ Diving Board and compatible offset mounts to be integrated into the setup. This makes the MICRO-226™ more than just a traditional optic riser—it’s a modular mounting platform designed around modern night vision and weapon configurations.
