In the field... seconds matter. If your optic sits too low; your head drops, your eyes shift, your posture breaks and that costs time. The Lerna and Hydra are the first optic mounts that offer a 2.91” Optic Centerline for faster target ID, regardless of gear/ equipment obstructions. The difference is immediate. Less strain on your neck, faster target transitions, and better awareness when it counts. Add UNITY™ Tactical’s revolutionary Flip-to-Center technology, the 2.91 FTC (Flip-to-Center) to bring any magnifier to the 2.91 height to pair with the GBRS Group Hydra Mounting Systems.
SAME HEIGHT. DIFFERENT TOOLS.
HYDRA MOUNT
Built for end users who demand full control while running an optic and accessories. By elevating your accessories, you free up rail space—so you never have to compromise your grip.
LERNA MOUNT
The same mounting system as the Hydra without the accessory mount. Built for end users who run optics only.
Flip To Center Mounts
The 2.91 FTC (Flip-to-Center) brings any magnifier to the 2.91" height to pair with GBRS Group Hydra Mounting Systems.
