The Gbrs Group Hydra V2 is a dual optic mount purpose-built for the Aimpoint Duty RDS, engineered to solve a real problem shooters face: gear getting in the way. Whether you're wearing comms headsets, a gas mask, or running night vision, a conventional red dot height leaves you craning your neck or losing your sight picture to obstructions. The Hydra V2 positions your optic centerline at 2.91 inches—high enough to clear most common equipment without forcing an awkward shooting posture.

That elevation unlock matters more than it sounds. A higher optic lets you keep your head up and spine vertical, which means better body armor presentation, faster target transitions, and improved situational awareness. You're not leaning into the gun; the gun fits into your natural stance. Gbrs Group designed this mount with duty and defensive use in mind, so every angle and material choice reflects real-world needs.

Construction is serious: 6061-T6 aluminum body with Type 3 hard anodize, paired with 17-4 PH stainless steel clamp bars and hardware finished in Melonite. The mount weighs 6.1 oz and ships with all the tools you need—long-reach T10 and 3/32" hex keys, plus a T25 bit—so you're ready to install straight out of the box.

Frequently Asked Questions

Will the Hydra V2 mount work with other red dots besides the Aimpoint Duty RDS?

This mount is designed specifically for the Aimpoint Duty RDS. Compatibility with other optics is not detailed in the available specifications, so we recommend confirming with the manufacturer or contacting us if you have a different sight in mind.

What tools do I need to install the Hydra V2?

Everything you need comes in the box. Gbrs Group includes long-reach T10 and 3/32" hex keys for mounting, plus a 1/4" drive T25 bit, so you won't need to source additional tools.

Why is the 2.91-inch centerline height important?

That height clears most common tactical gear—comms headsets, helmets, gas masks, and night vision—so your sight picture stays clear regardless of what you're wearing. It also lets you keep your head upright and spine vertical, which improves body armor presentation and situational awareness compared to a lower-mounted optic.

Is the FDE finish the same as standard black anodize?

The mount uses the same Type 3 Class 2 hard coat anodize per MIL-A-8625 military spec, but finished in FDE (Flat Dark Earth) instead of black. All stainless hardware and clamp bars are finished in Melonite for durability.
