The EOTech HHS UNITY I in black, part number HHS1 FTCU-BLK, is a complete holographic sight system: an EOTech EXPS3-0 holographic weapon sight and a G33 3x magnifier supplied together on a UNITY Tactical FAST FTC OMNI mount with the FAST Optic Riser.
Buying the sight, the magnifier and the mount separately is where most builds go wrong. This one arrives as a matched set at a known height, with nothing left to work out.
The EXPS3-0 projects a 68 MOA ring with a 1 MOA dot at 1x, with 20 brightness settings of which 10 are compatible with night vision, and turrets that move 0.5 MOA per click. Power comes from a single CR123 cell, which EOTech rates at 1,000 continuous hours at nominal setting 12 at room temperature. The complete system weighs 26.3 oz, measures 8.35 x 2.65 x 3.6 in and is rated to a depth of 33 ft (10 m).
The UNITY FAST FTC OMNI mount with its Optic Riser sets the optical centreline 2.26 in above the rail — a raised height rather than an iron-sight co-witness, which brings the head up off the stock and speeds up the sight picture in body armour or under a helmet. The magnifier lives on the same mount and swings to the centre behind the sight when magnification is wanted, so the ring and dot stay where they were the rest of the time. If your build is set up around a co-witness height, this is not that system.
The mount clamps to a MIL-STD-1913 Picatinny rail, so any flat-top AR-pattern upper or straight-pull receiver with enough rail length for both bodies will take it. The same system in tan is the HHS UNITY I in Tan, and for a co-witness-height hybrid on EOTech's own mounts see the HHS VI with the EXPS3-2 and G43. More sit in holographic sights.
