GBRS GROUP LERNA MOUNT KIT ACRO FDE

Description

The GBRS Group Lerna Mount Kit is built for shooters who run an Aimpoint ACRO on a helmet-mounted night vision setup and need a purpose-built solution rather than an improvised stack of adapters. The Lerna system exists to position a red dot at the correct offset for use alongside a night vision device, keeping the optic’s controls accessible and the sight picture consistent whether you’re working with or without the tube in front of your eye.

This variant is fitted for the Aimpoint ACRO footprint specifically, so the interface between mount and optic is designed around that sight’s geometry rather than relying on a universal adapter plate that can introduce slop or height inconsistency. The Flat Dark Earth anodized finish matches common earth-tone kit and holds up to the contact wear that comes with frequent mounting and dismounting cycles.

GBRS Group developed the Lerna through direct operational experience, which shows in the details: the mounting architecture prioritizes repeatable return-to-zero when the optic is removed and reinstalled, a practical concern for anyone who breaks down their kit between uses. The kit includes the hardware needed to complete the installation without sourcing additional components separately.

This is a specialized piece of equipment aimed at professionals and serious enthusiasts running a helmet-based optic system. If your use case is a straightforward rail-mounted red dot without a night vision component, a simpler mount will serve you better and cost considerably less. The Lerna earns its place on a build where the offset geometry and dedicated ACRO fit actually matter to how the system performs.
