GBRS Group Hydra V2 EXPS Scope Mount Kit | EOTECH Mount

The GBRS Group Hydra V2 EXPS Scope Mount Kit is a raised optic mount built for shooters running an EOTECH EXPS who want faster sight acquisition and better gear integration. It positions the optic at a 2.91 inch centerline, promoting a heads-up shooting posture that keeps your eyes level and your spine upright. This is the mounting philosophy modern professional shooters have moved to, and this kit executes it properly.

Why Shooters Are Going Tall

Traditional low mounts force you to crush your cheek into the stock and hunch behind the rifle, which slows visual processing and fights every piece of kit you wear. The Hydra from GBRS Group raises the EXPS to a height where your head stays upright and your eyes stay level.

Height also buys you speed up close, where a full cheek weld is a luxury you rarely get, because a coarse mount of the gun still puts the reticle in front of your eye. That forgiveness is exactly what fast shooting rewards. The taller sight picture is a real advantage when you work around ear protection, comms, gas masks, night vision, or body armor, since it clears the gear that blocks a traditional low mount. If you train in kit, this mount was designed for your reality.

GBRS Group Hydra V2 Feature Breakdown

The benefits stack up quickly once the optic comes up to height:

• 2.91 inch optic centerline that promotes a heads-up shooting posture
• Purpose-built fit for the EOTECH EXPS holographic sight
• Clears ear pro, comms, gas masks, night vision, and body armor
• Faster visual processing and stronger situational awareness
• More consistent cheek weld when shooting in full kit
• Machined and finished to hold zero on hard-use rifles

Specifications and Build Quality

The kit mounts to a standard Picatinny rail and lifts your EXPS to a 2.91 inch optic centerline, measured from the rail to the center of the optical axis. That number is the heart of the design, calculated to align the sight with a natural, upright head position. The GBRS Group Hydra V2 is machined to hold that geometry precisely, because a tall mount only works if it is rigid enough to keep the optic exactly where you zeroed it.

The kit is machined and finished to hold zero on hard-use rifles, which is precisely what you want from the one part connecting your point of aim to your barrel. A raised mount that wanders zero is worse than useless, and this one is built so that conversation never happens.

Setup and Real-World Use

Installation is straightforward: clamp the kit to your upper’s Picatinny rail, mount the EXPS, torque to spec, and confirm zero. From there, the height does the work, letting you drive the gun with both eyes open and your head up where the information is. Keep your torque wrench honest and the mount will do the rest.

The payoff shows up in quicker visual processing, better situational awareness, and a consistent cheek weld even under a helmet and night vision. Expect your presentation to adapt within a session or two, after which the upright posture becomes the natural way to drive the gun. Round out your sighting system from our complete optics department if you are still choosing the sight itself.

The GBRS Group Hydra V2 has become a favorite among shooters chasing an efficient, modern setup, and one range session in full kit explains why. Mount it once and shoot the way the gear was meant to work. Ships direct to your door, no FFL required.
