1.0 INTRODUCTION 1.1 General Information This manual is an overview of the XPS3/XPS2 Holographic Weapon Sight (HWS), and will define the basic operation, features/benefits, and options of this proprietary optical system. The HWS is a state of-the-art optical sighting system, employing holographic sighting technology for small to medium caliber weaponry and launching type platforms.
1.2 Key Attributes The XPS3/XPS2 HWS is a lightweight, non-magnifying, optical sight designed for Close Quarter Battle. It allows very fast target acquisition and engagement at short ranges while providing aiming capability out to 300 meters equal to or better than iron sights. The major combat advantage of the HWS is extremely rapid reticle-on-target acquisition. As quickly as a target is identified, the holographic reticle can be superimposed on the target.
• 2- 65 minute ring with vertical and horizontal stadia and (2) 1 MOA aiming dots Fig. 1 XPS reticle options The HWS 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) without obscuring the target. Another advantage of the HWS is the full field of view which allows the operator better situational awareness.
The XPS3 can operate in tandem with Generation I – III+ night vision intensifier tubes. Operators can see the holographic reticle image with helmet mounted or weapon mounted night vision devices. The HWS is a passive system and emits no signature from frontal or from a peripheral aspect. While in the NV mode, the sight is undetectable by opposing force night vision equipment. The HWS can be positioned behind night vision systems without any “bloom” on the target area.

2.1.3 Replacing the Battery Remove the battery cap by turning the cap counterclockwise until the cap pulls away from the battery compartment (Fig. 3). After the battery cap is removed, slide the battery out and replace it with a fresh one. A “+” marking can be found on the top of the battery cap ensuring correct battery orientation. To reinstall the battery cap, align the cap with the battery compartment and carefully begin to thread the cap, turning it clockwise.
2.1.4 Electronic Features All electronic controls are via pushbutton switches located at the rear of the unit housing as shown in Fig. 4. To ensure proper operation of the pushbutton switches, press firmly on the center of the switch. 1. ON/ Auto Battery Check Pressing the Up or Down Arrow pushbutton switches will turn the sight ON at Level 12. See item 4 under this section for a description of Auto shutdown. The sight will automatically perform a battery check every time it is turned on.
4. Auto Shutdown The HWS has an auto shutdown feature. If the sight is turned on by pressing the UP button, it will automatically shut itself OFF 8 hours after the last pushbutton control is used. The sight will automatically shut OFF after 4 hours if it is turned on by pressing the DOWN button.
2.1.5 Night Vision Mode On/Off Auto Shutdown The XPS3 HWS is compatible with Generation I - III+ Night Vision Devices. At the night vision settings, the reticle brightness is low enough that when viewed with a night vision device, the reticle image does not bloom. 1. ON/ Night Vision Mode and 8 Hour Auto Shut Down (XPS3) Pressing the NV Button (see Fig. 4) will turn the sight ON in Night Vision Mode.
2.1.6 Windage and Elevation Adjustments Fig 5: Adjustments The HWS features click mechanisms for elevation and windage adjustments. The elevation and windage adjustment are located on the right-hand side of the sight (Figure 5). The knob towards the front is the windage adjustment and the knob towards the rear is the elevation adjustment. Both of these adjustment mechanisms are grooved with a slotted screw head and require the use of a screwdriver, coin, or spent brass to turn.
shown in Fig. 5. For both elevation and windage, each click will change the bullet’s point of impact 1/2 Minute of Angle (MOA), ¼ inch (6.35mm) at 50 yards (45.7m), or ½ inch (12.7mm) at 100 yards (91m). Also, one full rotation of either knob will change the point of impact 10 MOA, 5 inches (127mm) at 50 yards (45.7m), or 10 inches (254mm) at 100 yards (91m). To move the point of impact UP, turn the elevation adjustment LEFT. To move the point of impact RIGHT, turn the windage adjustment RIGHT.
2.2 Preventive Maintenance Checks and Services (PMCS) OPERATOR LEVEL MAINTENANCE The operator is limited to replacing batteries and cleaning the battery compartment and outer housing surfaces of the sight. REPLACING BATTERY See the heading ‘Replacing Battery’ under section Description of Components, Controls, and Indicators. Do not use deteriorated or corroded batteries. Inspect battery for rips, tears, or cuts in the housing.
2. No maintenance is needed on the sight’s surface, except to occasionally wipe off with a soft cloth. Use only a water-based cleaner such as glass cleaner, ammonia, or soap and water. Never use any solvent-type cleaner such as alcohol or acetone. Do not use gun cleaner to clean or lubricate the HWS. 3. All moving parts of the sight are permanently lubricated. Do not try to lubricate them. 4.
Corrective Action 3: Inspect the battery contact points in both the battery cap and in the sight itself. Ensure that they are free of debris or corrosion. Corrective Action 4: Reset the electronics by removing any source of power for approximately two minutes. This will allow a capacitor in the electronics housing to drain of power, resetting the electronics. Reinstall the battery and operate the sight as normal. Corrective Action 5: Check the battery contacts for corrosion or wear. Clean the contacts.
Corrective Action 2: The reticle is projected onto your target plane. You must focus on it like you would any other object at that distance. Do NOT focus on the sight housing, rather, focus on your target. The outer ring is designed to be a reference to center, similar to a ghost ring. Corrective Action 3: If you wear corrective lenses for nearsightedness, you will require them to see the reticle in focus, as it is projected onto the target plane.
Corrective Action 3: Replace the battery with an Energizer brand battery. These have proven to be the most effective to withstanding a consistent amount of recoil. Many brands of batteries deteriorate faster than others and can result in these failures. Corrective Action 4: Turn the sight in for unit level maintenance. Failure: There is a streak in the reticle/ the reticle is dim/ the reticle fades in parts of the window: Corrective Action 1: Replace the battery.
2.4 Unit Level Maintenance and Repair The Unit Armorer or individual responsible for unit level maintenance is only authorized to replace or repair the following items: – Battery – Battery Cap – Protective Hood and Hood Screws – Technical Manual – Knurled weaver bolt Please see Additional Authorized Items in Appendix A for the corresponding NSN numbers for the above listed components.
2. Call or email L-3 EOTech’s Customer Service Department at the following: (734) 741-8868 x2178 general@L-3com.com 3. Be sure to leave a name, contact number, return shipping address, and failure description in the email or on a voice mail. This will allow the manufacturer to generate a Return Authorization Number (RA#) to include with the sight(s). DO NOT SHIP THE SIGHTS WITHOUT A RETURN AUTHORIZATION NUMBER (this will severely delay the turn around time on repair or replacement). 4.
2.5 Installation of Equipment MOUNTING The HWS is equipped with mounting hardware to attach to a 1” (25.4mm) Weaver or MILSTD-1913 Picatinny style rail. To achieve the best results and accuracy, the HWS must be mounted properly. The rail needs to be as parallel as possible to the bore to permit the maximum elevation and windage adjustments. If it is required, it is strongly recommend that the rail be installed by a qualified gunsmith. To mount the sight, please follow these steps.
BORE SIGHTING Bore sighting is a good preliminary procedure in achieving proper alignment of your sight to the firearm. A chamber laser/ bore sighter is an aid in achieving collomation. LIVE FIRE SIGHTING FOR AN M-4 OR M-16 To employ the aiming dot of the HWS reticle from 10 to 300 meters, the sight can be zeroed at 25 meters using a standard M4/M16 military zeroing target.
