OPERATOR’S MANUAL FOR HWS 557.AR223 REFLEX SIGHT, HOLOGRAPHIC, NV COMPATIBLE, AA, L-3 EOTECH ORDER CODE: 557.AR223 See inside cover for distribution statement. L-3 Eotech Technical Manual ver. 1.0 APRIL 2007 DISTRIBUTION STATEMENT: Distribution is authorized to U.S. Government agencies and their contractors. This publication is required for administration and operational purposes. Additional copies of this document can be found on the manufacturer’s website. Written requests must be referred to: L-3 EOTech Service Dept. Attn: TM Request 1201 E.Ellsworth Rd. Ann Arbor, MI 48108 (734)741-8868 x3688 [email protected] DESTRUCTION NOTICE: Destroy the sight’s operability by removing the battery cap, batteries, and then crushing the battery cap. Destroy this document by any method that will prevent disclosure of contents or reconstruction of the document. WARNING WEAPON SAFETY: Prior to mounting the Holographic Weapon Sight (HWS) on a weapon, be sure the weapon is cleared. If you are not sure how to clear the weapon, please see the operator’s manual for the weapon platform you are mounting the HWS on. LASER SAFETY: The HWS is a Class II laser product. The Class II level illuminating beam, however, is completely blocked by the housing. The only laser light accessible to the eye is the image beam and produces a power level that is within the limit of a Class IIa laser product. The illuminating beam can be viewed directly by eye if the housing is broken. Turn the sight off immediately and return the broken unit to the factory for repair. FCC COMPLIANCE: The HWS complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation. CAUTION • Never remove any screws or disassemble the sight’s optical housing components. The optical cavity is nitrogen filled and sealed to prevent internal fogging. • Disassembly will void the warranty and render the sight inoperable. • Always check to make sure the sight is off before pressing the NV button to turn on the sight in the Night Vision mode. Otherwise, it will toggle to the Normal mode and saturate the image intensifier. • When a sudden increase in resistance is felt in the elevation or windage adjustment shafts, the end of the adjustment range has been reached. DO NOT TURN THE ADJUSTMENTS ANY FARTHER OR SERIOUS DAMAGE TO THE SIGHT MAY OCCUR. • Never clean the glass surface with a dry cloth or paper towel; always dampen the glass surfaces prior to cleaning • All moving parts of the sight are permanently lubricated. Do not try to lubricate them. • Do not use deteriorated or corroded batteries. Inspect batteries for rips, tears, dents, or cuts in the housing. If there is any exposed internal content of the battery, it could negatively effect the operation of the sight.

The sight utilizes a proprietary optical system which employs holographic sighting technology for small to medium caliber weaponry and launching type platforms. The sight incorporates holographic optics technology such as that used to produce advanced heads-up displays in attack fighter aircraft for targeting, gauge reading, weapon system verification, etc. L-3 EOTech has miniaturized a similar heads-up display system into a compact and rugged package for use on small arms and other weapon platforms. The sight type is commonly referred to as a reflex sight. 1.2 Key Attributes • The 557.AR223 reflex sight is a lightweight, non-magnifying, optical sight designed for Close Quarter Battle. It allows very fast target acquisition and engagement at short range while providing aiming capability out to 300 meters equal to or better than iron sights. The sight can, however, be used in conjunction with an L-3 Eotech Optical Magnifier. When an Optical Magnifier is used, the effective range is extended to 600 meters. By utilizing the aim point indicators of the AR223 Ballistic Reticle (Figure 1), high accuracy placement of rounds can be achieved. Figure 2: AR223 Ballistic Reticle • The major combat advantage of the reflex sight is extremely rapid reticle-on-target acquisition. As quickly as a target is identified, the holographic reticle can be superimposed on the target. The sight allows operators to maintain eye contact on the target and to place the holographic reticle onto the target without shifting eye focus. • An Operator can quickly acquire the target and reticle in the same focal plane for fast and accurate shot placement. • The 557.AR223 appears to project the holographic image of a reticle on the target plane. The sight can be used as a bright open reticle image or a fine dot which is limited only by the acuity of the shooter’s eye. The reticle is parallax free and the holographic heads-up display window allows an undistorted and unrestricted view of the target. • The 557.AR223 offers extremely fast target acquisition in Close Quarter Battle (CQB) using the large ring, and aiming precision in longer range engagements (using the MOA Dot array) without obscuring the target. • An advantage of the 557.AR223 is the full field of view which allows the operator better situational awareness. The sight’s true heads-up display window eliminates blind spots and constricted or tunnel vision associated with scope sights. Controls are inset into the Reflex Sight housing with no protruding knobs, battery compartments, or rings that would obscure the target. Utilizing natural binocular vision is an advantage of this sighting system, as well as additional threat identification through increased operator situational awareness and peripheral vision. The reflex sight can be naturally employed by all levels of users, from novice to the most highly trained operator. The 557.AR223 HWS can operate with Generation I – IV+ night vision intensifier tubes. Operators can see the holographic reticle image with helmet mounted or weapon mounted night vision devices. The optic design is a passive system which emits no signature from a frontal or peripheral aspect. While in the NV mode, the sight is undetectable by opposing force night vision equipment. The HWS can be used with night vision systems without any “bloom” on the target area. The primary use of the 557.AR223 is for the M4A1 carbine in Close Quarters Battle. The sight provides a 1X (no magnification) sight picture. However, it can be used as an effective longer range sight when used with a magnification device. 1.3 Equipment Description Operation • Optics: Transmission holography – 100% parallax free • Magnification: 1x Eye Relief: Unlimited Length/Width/Height: 4.9”x1.8”x2.8” Weight: 12.3 oz • Temperature: -40 to 150 F • Waterproof: Submersible to 33 ft of water depth • Sealing: Fog-proof internal optics • Color/Finish: Non-reflective black on most exposed surfaces • Adjustment (per click): 0.5 MOA (1/2” at 100 yds) • Adjustment Range: +/- 40 MOA travel • Mount: MIL-STD 1913 mounting rail • Return to Zero: Repeatable to 1 MOA after re-mounting Heads-Up Display Window • Optical Surfaces: Anti-glare coating • Window Dimensions: 1.20” x 0.85” (30 x 23mm) • Field of View (100 yds): 30 yds (28m) at a 4” eye relief • Reticle: 65MOA circle with quadrant ticks and within the circle, a vertical four-dot ballistic aiming array, each 1 MOA in size – calibrated to the ballistic drop of .223 caliber ammunition Electrical • Brightness Adjustment Range: 110,000: 1 brightest to lowest • Night Vision Brightness Range: 1000: 1 with NV switch engaged • Power Source: 2 x AA batteries • Battery Life: 1,000 continuous hours at nominal setting 12 with lithium batteries, 600 hours with alkaline batteries • Brightness Settings: 30 settings with scrolling feature (10 settings for NV use) • Auto Battery Check Indicator: Flashing reticle upon start-up • Auto Shut-down: At 8 hrs- programmable to 4 hrs Figure 3: Locations of Components Figure 4: Location of Components Holographic Window - Contains the embedded holographic reticle pattern that forms a virtual image of the reticle when illuminated by the integral laser Hood – Pre-assembled, protective hood that covers the optical housing of the sight to protect the sight from impact damage.
