"Ideal for firearms with limited rail space, the GBRS Group Hydra V2 Mount is the industry's first dual optic mount with a comfortable 2.91"" center height. The 2.91"" center height provides faster target ID regardless of gear obstruction like ear protection or comms, gas masks, and night vision. The higher optic allows for a more athletic shooting position that maintains proper body armor presentation. The Hydra V2 Mount offers an elevated MIL-STD 1913 Picatinny rail for attaching accessories like lights, optics, thermals, and more. The elevated position keeps your accessory closer to your mounted red dot, helping to balance your loadout. The pass-through design allows for simple cable management or iron sight use. Each Hydra V2 Mount is made from 6061-T6 aluminum with Type 3 hardcoat-anodized finish. The clamp bar, mounting hardware, and washers are made from stainless steel. Includes mounting hardware.
