GBRS Group Lerna Mount Kit

Heads Up. Stay Ahead.

The Lerna Optic Mount is a precision-engineered stand-alone mount designed to put your optic at a 2.91″ centerline—giving you faster target acquisition and unmatched situational awareness in high-stakes environments. Whether you’re running comms headsets, gas masks/CBRN gear, or night vision, this raised optic height delivers a more athletic, heads-up shooting posture that’s built to dominate.

Constructed from rugged 6061-T6 aluminum with a Mil-Spec anodized finish, the Lerna keeps your rig mission-ready in any condition. Stainless steel clamp bars and screws ensure bombproof reliability, while the modular compatibility covers AIMPOINT® MICRO, AIMPOINT® ACRO, EOTECH®, and Trijicon® MRO footprints.
