DESTRUCTION NOTICE: Destroy the sightʼs 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.
This defense article is controlled under the International Traffic in Arms
Regulations (ITAR), and may not be exported to a Foreign Person, either in the U.S.
or abroad, without a license or exemption from the U.S. Department of State.
The 553 is designed to mount only to rail systems that are made to the dimensions
of the current MIL-STD-1913 rail specification. Rails which do not meet the
dimensional requirements of the MIL-STD-1913 specification may result in the
sight fitting loosely, moving on the rail during recoil, or not allow the cam levers to
close properly.
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.
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.
• There is a 12 volt battery that is approximately the same size as the Type N 1.5 volt
alkaline battery used in the M551. DO NOT USE the 12 volt batteries. They will
severely damage the sight.
• When used with a Night Vision 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 effect the operation of the sight.
• The SU-231/PEQ (HWS M553) is designed to mount only to rail systems that are
made to the dimensions of the current MIL-STD-1913 rail specification. Rails which
do not meet the dimensional requirements of the MIL-STD-1913 specification may
result in the sight fitting loosely, moving on the rail during recoil, or not allow the cam
levers to close properly.

1.0 INTRODUCTION
1.1 General Information
This manual is an overview of the SU-231/PEQ (M553), M552, and the M551
Holographic Weapon Sights (HWS) or Reflex Sight, and will define the basic
operation, features/benefits, and options of this proprietary optical system. The Reflex
Sight is a state of-the-art optical sighting system, employing holographic sighting
technology for small to medium caliber weaponry and launching type platforms. The
Reflex Sight 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 SU-231/PEQ (M553), M552, and the M551 reflex sights are lightweight, nonmagnifying, optical sights designed for Close Quarter Battle. They allow 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 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 focus.
Operators can quickly acquire the target and reticle in the
same focal plane for fast and accurate shot placement.
The reflex sight 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 reflex sight standard reticle is displayed in Figure 1: 65 minute ring with vertical
and horizontal stadia and a one MOA aiming dot.

Fig 1:
Standard
Reticle
The reflex sight 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 Reflex Sight is the full field of view which allows the operator
better situational awareness. The Reflex Sight 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 Reflex Sight 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 reflex sight can operate in tandem 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 reflex sight 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.
The primary use of the reflex sight is for the M4A1 carbine and CQBR in Close
Quarters Battle. The reflex sight is not however, limited to carbines. The reflex sight
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.
3
The advantage of the reflex sight is that it provides the operator superior shooting
performance, rapid reticle-on-target acquisition, full field of view and accurate shot
placement. The reflex sight can be naturally employed by all levels of users, from
novice to the most highly trained operator.
