The Lerna is the first standalone mount to offer a 2.91" sight height, enabling faster target acquisition regardless of additional equipment such as ear protection/communication headsets, gas masks/CBRN gear, or night vision devices, which can interfere with conventional mounts. The elevated optic position promotes a more athletic, upright posture, allowing the user to maintain a straight spine and improving body armor presentation. This “heads-up” shooting style enhances processing speed and situational awareness.

Special Offer – HYDRA Mount V2 for EOTECH EXPS (Black) Product Description The GBRS Group HYDRA Mount V2 provides a 2.91" (73.9 mm) optical centerline height, enabling faster target acquisition regardless of additional equipment such as ear protection/communication headsets, gas masks/CBRN gear, or night vision devices, which can interfere with traditional mounts.

Design & Functionality The unique and patented design features a raised MIL-STD-1913 (Picatinny) platform, allowing direct attachment of accessories such as lights, optics, thermal devices, and aiming systems. It is especially suited for compact PDW/SMG platforms, where rail space is limited but mounting both a light and an aiming device remains essential. Variants for AIMPOINT® and Trijicon® include dedicated cutouts for improved cable management. Key Advantages 2.91" optic height for faster target acquisition Improved ergonomics with upright shooting posture Reduced interference from mounted equipment Ideal for use with night vision, CBRN gear, and comms systems Raised Picatinny platform for additional accessories Optimized for compact weapon platforms Improved weight distribution over the magazine well Reduced visual obstruction Performance Benefit There is no longer a need to compromise grip due to mounted equipment or to shift hand placement because of limited rail space. By elevating accessories such as lights or lasers and positioning them closer to the red dot optic, visual obstruction is minimized and weight is centralized—resulting in better handling and overall performance.
