The Eotech 552.XR308 Holographic Weapon Sight (HWS) is specially configured with a bullet drop compensating reticle to make the most of the longer range and heavier hitting .308 Winchester (7.62×51) cartridge used by sniper and designated marksman rifles such as the Mk 11 Mod 0, M14, Mk14 Mod 0 Enhanced Battle Rifle, M39 Enhanced Marksman Rifle and M110 Semi Automatic Sniper System or machine guns such as the M240 and Mk48 series. The reticle on the XR308 red dot sight enables great accuracy out to the distance at which targets can be identified. To extend this range by several hundred metres an Eotech G23.FTS 3x magnifier can be mounted behind the HWS. This is compatible with Aimpoint or Eotech sights and flips to the side to enable use of the HWS at close quarters.
The Eotech 552.XR308 HWS employs the latest solid-state electronic technology. No less than 20 brightness levels enable the Eotech 552.XR308 to adapt to any lighting conditions. The battery check indicator, up/down brightness scrolling and (programmable) auto shutdown are controlled by an on-board microprocessor. The electronics are protected by encapsulation in a shock absorbing resin compound.
The holographic patterns are visible in any light, center instinctively regardless of weapon hold, and remain visible while sweeping the target area. Reticles are large and semi transparent to ensure the fastest possible engagement without obscuring the target.
The HWS utilizes a fighter jet style ‘Heads-Up Display’ (HUD) that eliminates the obstructions and restricted angle of vision associated with other types of red dot sight. Holographic vs red dot this is a key advantage. The controls do not protrude from the Eotech 552.XR308’s streamlined housing and nothing obstructs the view of the target area. You keep both eyes open whilst shooting, ensuring full situation awareness and rapid engagement of emerging threats.
Partial obstruction of the window will not prevent aiming. In the unlikely event that the window is shattered the Eotech will remain fully functional! As long as you can see through any portion of the window, the entire aiming pattern will be visible on target and you can shoot accurately. Aimpoint vs Eotech the Aimpoint is easier to prevent being obstructed with its flip up lens caps but a flip up Eotech 552 scope cover is now available from GG&G.
The Eotech 552.XR308 Holographic Weapon Sight has been tested in the most extreme conditions and will perform consistently and reliably in any operational environment. It is proof against water, fog, shock and extremes of temperature.
The HWS has been subjected to military drop tests and consistently remained operational and held its zero. Other tests utilized a recoil simulator to subject the sight to 3,500 Gs of acceleration in under 0.5 milliseconds (this approximates to mounting on a .454 Casull handgun) as well as chambers simulating various environmental conditions.
The HUD is made of 3/16″ thick, three layer, shatterproof laminate glass for extreme durability. For additional protection a rugged ‘roll bar’ hood covers the optical components of the sight.
The Eotech 552.XR308 does not project any radiation or give off any visible signature. Even Gen III night vision cannot detect any signature from this sight.
The HWS is fully compatible with all generations of Night Vision equipment and features no less than 10 night reticle brightness settings to cater for different NV equipment and conditions. A typical installation would involve a removable or swing out image intensifier behind the HWS but the Eotech 552.XR308 can be placed behind NV devices without generating bloom and is highly suitable for use with head mounted NV, even with partial cheek-weld, offering the operator great flexibility in employment. NV use brings out the enormous advantage of the HWS concept, providing four times more field of view than an Aimpoint Comp M2 and ten, as opposed to four NV compatible brightness settings.
The Model 552 series has been adopted by the DEA, ATF and FBI SWAT and is by far the most popular Holographic Weapon Sight. This sight is NV compatible and uses readily avialable AA batteries. The Eotech 552.XR308 has been adopted by the Stryker Brigade and the 10th Mountain, and 3rd Infantry Divisions. It has been proven in the most rugged conditions, undertaking a vast range of missions on the most powerful military weapons.
