GBRS Lerna Mount | Aimpoint Duty RDS | FDE

The GBRS Lerna mount positions an Aimpoint Duty RDS at a 2.91-inch optic centerline to improve the sight picture when users wear hearing protection, communication headsets, gas masks/CBRN gear, or night-vision systems. The elevated optic allows a more heads-up stance and helps maintain vertical spine alignment, which can be beneficial when wearing body armor or protection plates. It is intended for end-users who need an optic mounting solution compatible with Aimpoint Duty RDS footprints.
