PRODUCT SPECIFICATIONS
POWERING UP AND POWERING DOWN THE RED DOT
Depress and release the “+” or “-” button to power up the red dot; press “+” and “-” button to
power down the red dot. This red dot has a convenient auto-o feature that will switch o
the device if it has been left on for more than 4 hours. If the unit shuts down automatically,
moving or lifting the gun will turn the unit on again automatically. However, if the unit is
turned o by pressing “+” and “-” simultaneously, the unit will not be turned on automatically
by moving or lifting the gun.
ADJUSTING BRIGHTNESS
Pressing the power button repeatedly will step through 10 brightness settings. Select the
lowest brightness setting that still provides good contrast against the target; using too high
a setting may make the reticle appear distorted.
BATTERY
This red dot comes equipped with 3-volt lithium battery, NEDA type 2032. It is installed with
the positive side “+” down.
INSTALLATION
CAUTION: BEFORE YOU BEGIN, ENSURE THAT THE FIREARM IS CLEAR. REMOVE MAGAZINE,
LOCK ACTION OPEN AND VISUALLY INSPECT TO ENSURE THAT THE CHAMBER IS CLEAR.
To get the best performance from your red dot, it must be mounted properly. If you are not
familiar with mounting a red dot, it is strongly recommended that you seek the assistance of
a qualied professional.
MOUNT ONTO A PICATINNY OR WEAVERSTYLE RAIL
Your sight has integrated mounting rails that attach to a standard Weaver-style base
or Picatinny rail.
Loosen the mounting screw and set the sight onto the mounting base of the rearm. The
mounting screw should t into one of the grooves in the top of the mounting base. Be sure
the sight is fully seated on the mounting base before tightening the mounting screw.
( DO NOT OVER TIGHTEN MOUNTING HARDWARE. MAX. TORQUE 20 INCH LBS. )
For additional security, a drop of thread-locker can be added to the mounting screw.
ZEROING
Initial Setup
The dot position has been pre-set at the factory. Only minor windage and elevation
adjustments should be required. If possible, a bore sighting device should be used for rough
alignment of the sight to the rearm. If bore sighting is not possible, place the rearm on
a sturdy rest and look through the barrel or along the rail at a small target about 25 yards
away. Turn on the red dot and select a suitable brightness. Using a straight-slot screwdriver,
adjust the windage and elevation until the dot position corresponds with the target. Note
the following when making adjustments.
Click value: 1 MOA (approximately 1” at 100 yards; ¼” at 25 yards)
Windage: Counterclockwise (indicated by arrow) moves point of impact right/clockwise, left.
Elevation: Counterclockwise (indicated by arrow) moves point of impact up/clockwise, down.
FINAL SETUP (LIVE FIRE)
CAUTION: USE ADEQUATE EYE AND EAR PROTECTION AT ALL TIMES. SHOOT ONLY AT AN
APPROVED RANGE OR SUITABLE SAFE AREA.
CAUTION: IF YOU HAVE USED A BORE SIGHTER, CONFIRM THAT THE BORE SPUD IS NO
LONGER IN THE MUZZLE AND THAT THE BORE IS UNOBSTRUCTED.
Position the target no further than 25 yards away to begin the zeroing process. Turn on
the red dot and select a suitable brightness. Carefully re three shots and note where they
strike on the target. Your group should strike the target no greater than 10” from your point
of aim. (Should the group be farther away than this, the mounting process is faulty and
must be corrected before proceeding.) Make adjustments to windage and elevation so that
your group strikes the target approximately 1” beneath the point of aim with no windage
error (at six o’clock, neither left nor right).
When complete, position the target at the desired zero distance. Fire three rounds at this
distance and adjust as necessary to hit dead-on.
RETICLE
Your sight uses a 3 MOA reticle pattern. One MOA is about 1” at a distance of 100 yards (or
3/4” at 75 yards, 1/2” inch at 50 yards, etc.).
MIRROR ANGLE
The mirror-lens can be easily seen when looking through the wrong end of the sight. The tilt
of the mirror-lens is not a defect. It is tilted to reflect the LED’s light back to the user’s eye.
CAUTION: BEFORE YOU BEGIN, ENSURE THAT THE FIREARM IS CLEAR. REMOVE
MAGAZINE, LOCK ACTION OPEN AND VISUALLY INSPECT TO ENSURE THAT THE CHAMBER
IS CLEAR.

be turned on automacally by moving or liing the gun.
Adjusng Brightness
Pressing the power buon repeatedly will step through 10 brightness sengs. Select the
lowest brightness seng that sll provides good contrast against the target; using too
high a seng may make the recle appear distorted.
Baery
This red dot comes equipped with 3-volt lithium baery, NEDA type 2032. It is installed
with the posive side “+” down.
INSTALLATION
CAUTION: BEFORE YOU BEGIN, ENSURE THAT THE FIREARM IS CLEAR. REMOVE
MAGAZINE, LOCK ACTION OPEN AND VISUALLY INSPECT TO ENSURE THAT THE CHAMBER
IS CLEAR.
To get the best performance from your red dot, it must be mounted properly. If you are
not familiar with mounng a red dot, it is strongly recommended that you seek the
assistance of a qualified professional.
Mount onto a Picanny or Weaver-style rail
Your sight has integrated mounng rails that aach to a standard Weaver-style base or
Picanny rail.
Loosen the mounng screw and set the sight onto the mounng base of the firearm. The
mounng screw should fit into one of the grooves in the top of the mounng base. Be
sure the sight is fully seated on the mounng base before ghtening the mounng screw.
(DO NOT OVER TIGHTEN MOUNTING HARDWARE. MAX. TORQUE 20 INCH LBS.) For
addional security, a drop of thread-locker can be added to the mounng screw.
ZEROING
Inial Setup
The dot posion has been pre-set at the factory. Only minor windage and elevaon
adjustments should be required. If possible, a bore sighng device should be used for
rough alignment of the sight to the firearm. If bore sighng is not possible, place the
firearm on a sturdy rest and look through the barrel or along the rail at a small target
about 25 yards away. Turn on the red dot and select a suitable brightness. Using a
straight-slot screwdriver, adjust the windage and elevaon unl the dot posion
corresponds with the target. Note the following when making adjustments.
Click value: 1 MOA (approximately 1" at 100 yards; ¼” at 25 yards)
Windage: Counterclockwise (indicated by arrow) moves point of impact right/clockwise,
le.
Elevaon: Counterclockwise (indicated by arrow) moves point of impact up/clockwise,
down.
Final Setup (Live Fire)
CAUTION: USE ADEQUATE EYE AND EAR PROTECTION AT ALL TIMES. SHOOT ONLY AT AN
APPROVED RANGE OR SUITABLE SAFE AREA.
CAUTION: IF YOU HAVE USED A BORE SIGHTER, CONFIRM THAT THE BORE SPUD IS NO
LONGER IN THE MUZZLE AND THAT THE BORE IS UNOBSTRUCTED.
Posion the target no further than 25 yards away to begin the zeroing process. Turn on
the red dot and select a suitable brightness. Carefully fire three shots and note where
they strike on the target. Your group should strike the target no greater than 10" from
your point of aim. (Should the group be farther away than this, the mounng process is
faulty and must be corrected before proceeding.) Make adjustments to windage and
elevaon so that your group strikes the target approximately 1" beneath the point of aim
with no windage error (at six o’clock, neither le nor right).
When complete, posion the target at the desired zero distance. Fire three rounds at this
distance and adjust as necessary to hit dead-on.
RETICLE
Your sight uses a 3 MOA recle paern.
One MOA is about 1” at a distance of 100 yards (or 3/4” at 75 yards, 1/2” inch at 50 yards,
etc.).
MIRROR ANGLE
The mirror-lens can be easily seen when looking through the wrong end of the sight. The
lt of the mirror-lens is not a defect. It is lted to reflect the LED’s light back to the user’s
eye.
MAINTENANCE & CLEANING
Although your red dot is extremely durable, it is a precision instrument that should be
treated with reasonable care.
Lenses
The opcal coangs are hard and will last indefinitely with proper care.
Should either protecve windows become dirty, blow loose materials off before cleaning.
Use lens cleaning fluid and a so cloth to dab at the surface and remove any abrasive bits
of dust and dirt before applying more pressure. Be paent and clean in steps so as to not
grind abrasive dirt into the lens.
Exterior
Should the exterior become dirty, it may be cleaned with a damp cloth. Do not use oil or
solvents as they may be harmful if inadvertently rubbed onto the opcal coangs.
STORAGE
This red dot has been constructed using adhesives and lubricants that enable a broad
range of operaonal and storage environments. The grease used is temperature-stable
from -50 to +175 degrees Fahrenheit. Do not store at temperatures outside this range
(for example a car trunk on a very hot day).
