WARNING

WEAPON SAFETY: Prior to mounting the HWS® on your weapon, be sure the weapon is
cleared. If you are not sure how to clear your weapon, please see the accompanying
operator’s manual for the weapon platform you are mounting the sight 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 is at a power level within the limit of a Class IIa laser product. The
illuminating beam can become accessible to the 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. Complies with 21 CFR Chapter 1, Subchapter J.

CAUTION

• Never disassemble the sight’s optical assembly. The optical cavity is purged, nitrogen
filled, and sealed to achieve fog proof performance. Disassembly will void the warranty
and render the sight inoperable.

• When using a Night Vision compatible HWS® in tandem with an NV device, 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 MAY OCCUR TO THE
SIGHT.

• 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
affect the operation of the sight.

• The XPS2 HWS® units are designed to mount directly to either a 1”(25.4mm) weaver or

MIL-STD-1913 rail specification.

1.0 INTRODUCTION

1.1General Information

This manual is an overview of the XPS2 HWS® (Holographic Weapon Sight), 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. The HWS® utilizes
holographic optics fabrication technology that is used in the production of advanced heads
up display in attack fighter aircraft for targeting, gauge reading, weapon system verifica­tion, etc. L-3® EOTech® has miniaturized the sophisticated sighting heads up display system
into a compact and rugged package for use on small arms and other weapon platforms.

1.2Key Attributes

The 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. The sight allows operators to maintain eye contact on the target and to place the
holographic reticle onto the target without shifting focus. Operators can quickly acquire
the target and reticle in the same focal plane for fast and accurate shot placement.

The HWS® 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 pattern is parallax free and the holographic heads up
display window allows an undistorted and unrestricted view of the target.

The XPS2 is offered with one of the following (3) reticle options (see fig. 1):

• 0- 65 minute ring with vertical and horizontal stadia and a 1 MOA aiming
dot.

• 1- Single 1 MOA aiming dot (no outer ring)

• 2- 65 minute ring with vertical and horizontal stadia and (2) 1 MOA aiming
dots

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 HWS® employs a true heads up display (HUD) window that
eliminates blind spots and constricted or tunnel vision associated with scope sights.
Controls are inset into the HWS® housing with no protruding knobs, battery compartments,
or rings obscuring 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 primary use of the HWS® is for the M4A1 carbine and CQBR in Close Quarters Battle. The
HWS® is not however, limited to carbines. The HWS® is currently employed on medium
caliber machine guns, grenade launchers and less than lethal projectile launchers. The
sight provides a 1X (no magnification) sight picture and is not designed as a long range
sight system, however, it can be used as effectively as iron sights on targets to 300 meters.

The advantage of the HWS® is that it provides the operator superior shooting performance,
rapid reticle-on-target acquisition, full field of view and accurate shot placement. The
HWS® can be naturally employed by all levels of users, from novice to the most highly
trained operator.
