HYDRA is the first dual optic mount designed for end-users that provides a 2.91" optic centerline for quicker target identification, regardless of gear or equipment obstructions, such as EarPro/Comms headsets, gas masks/CBRN, and night vision devices. A higher optic position promotes a more athletic posture and a heads-up attitude, allowing users to keep a vertical spine, which benefits body armor or presenting plates to the threat. This heads-up style enables faster processing and improved situational awareness.Features :Elevated MIL-STD-1913, or Picatinny Platform for Directly Attaching Accessories Such as Lights, Optics, Thermals and Aiming Devices,Includes 1/4" Drive T25 Bit,Compatible with Most Holographic Weapon Sights (HWS) with Similar Footprints such as the EOTECH XPS Series
