Red Dot Sight Mounts are essential accessories for securely attaching red dot sights to firearms, ensuring stability, co-witness options, and precise alignment. Whether for rifles, shotguns, or pistols, the right mount enhances accuracy, durability, and overall shooting performance.

Key Features of Red Dot Sight Mounts:

• Secure Locking Mechanisms – Prevents sight movement and maintains zero, even under heavy recoil.
• Quick-Detach (QD) & Fixed Mount Options –
  • QD mounts allow for rapid removal and reattachment while maintaining zero.
  • Fixed mounts provide a rock-solid, permanent attachment.
• Absolute & Lower 1/3 Co-Witness Options –
  • Absolute co-witness aligns the red dot with iron sights.
  • Lower 1/3 co-witness places the dot slightly above iron sights for a clearer sight picture.
• Multiple Heights & Offset Configurations – Designed for optimal eye relief and ergonomic aiming.
• Lightweight, Durable Construction – Made from aerospace-grade aluminum or titanium, offering strength without excess weight.
• Compatibility with Major Footprints – Works with popular red dots like Trijicon RMR, Holosun, Aimpoint, SIG Sauer, EOTech, and Vortex.

  GBRS Group GBRS Group Hydra V2 Mount Kit Fits EOTECH FDE - GEAR-HYDRA2-ET-FDE

  8 in stock

  HYDRA is the first dual optic mount designed for end-users that offers a 2.91" Optic Centerline for faster target ID, regardless of gear/ equipment obstructions, i.e.. EarPro/Comms headsets, Gas masks/CBRN, and Night vision use. A higher Optic allows for a more athletic posture and Heads-up attitude that enables the end-users to maintain a vertical spine which translates to body armor or presenting plates to the threat. This Heads-up style allows for faster processing speed and increased situational awareness. The unique and patented design offers an elevated MIL-STD-1913, or Picatinny platform for directly attaching accessories such as lights, optics, thermals, and aiming devices. It's perfect for the super short PDW/SMG platforms where rail space is limited, but mounting a light and aiming device is still critical. The pass-through on the neck allows for cable management or iron sight passthrough on the AIMPOINT and Trijicon variants. Allen wrench pass through holes for easier optic mounting Shorter back base allows for FTC magnifiers to be closer to the red dot optic Screws and clamp are custom heated treated, black Nitrided stainless steel Strengthened neck to allow for wider cable management Holes for direct mount laser screws Anodized coating SKU: GEAR-HYDRA2-ET-FDE UPC: 850066219683
