Specifically designed for the tactical, law enforcement and committed
precision shooting communities, the Razor HD®Gen IITM series of
riflescopes offer the highest levels of performance and reliability.
Reticle Focal Plane
All riflescope reticles can be termed either first focal plane (FFP)
or second focal plane (SFP), depending upon their internal location
within the riflescope. This Razor HD Gen II riflescope features a
first focal plane reticle.
First focal plane (FFP) reticles are located within the riflescope
near the windage and elevation turrets in front of the imageerecting and magnifying lenses. This style of reticle will visually
grow and shrink as you change the magnification. The advantage
of an FFP reticle is that the reticle subtensions used for ranging,
holdovers, and wind drift corrections are consistent at all
magnifications. Usually, the reticle will appear heavier at higher
magnifications and finer at lower magnifications.
MOA and MRAD Adjustments
Depending on which version you have purchased, your Razor HD
riflescope will feature adjustments and reticles scaled in MOAs or mrads.
Both minute-of-angle (MOA) and milliradian (mrad) unit of arc scales
are equally effective when ranging or adjusting riflescope for bullet
MOA unit of arc measurements are based on degrees and minutes. There
are 360 degrees in a circle and 60 minutes in a degree for a total of 21,600
minutes (MOA) in a circle. A minute of angle will subtend 1.05 inches
at a distance of 100 yards (29.1 mm at 100 meters). Razor HD riflescopes
with MOA adjustments use .25 minute clicks which subtend .26 inches at
100 yards (7.3 mm at a 100 meters), .52 inches at 200 yards (14.6 mm at
200 meters), .78 inches at 300 yards (21.9 at 300 meters), etc.
Mrad unit of arc measurements are based on the radian. A radian is the
angle subtended at the center of a circle by an arc that is equal in length
to the radius of the circle. There are 6.283 radians in all circles and 1000
milliradian in a radian for a total of 6283 milliradians (mrads) in a circle.
An mrad will subtend 3.6 inches at a distance of 100 yards (10 cm at 100
meters). Razor HD riflescopes with mrad adjustments use .1 mrad clicks
which subtend .36 inches at 100 yards (1 cm at 100 meters) .72 inches
at 200 yards (2 cm at 200 meters), 1.08 inches at 300 yards (3 cm at 300
Vortex Razor HD riflescopes use a fast focus eyepiece designed to quickly
and easily adjust the focus on the riflescope’s reticle.
To adjust the reticle focus:
1. Look through the riflescope at a blank
white wall or up at the sky.
2. Turn focus knob fully outward.
3. Slowly turn the eyepiece focus knob inward
until the reticle image is as crisp as possible.
When focusing, look at the reticle with short,
interrupted glances rather than an extended
Once this adjustment is complete, it will not
be necessary to re-focus every time you use the
riflescope. However, because your eyesight may change over time, you
should re-check this adjustment periodically.
Looking directly at the sun through a riflescope, or any optical
instrument, can cause severe and permanent damage to your eyesight.
Variable Power Adjustments
To change magnifications, turn the magnification ring to the desired
External Rotation Indicator
The external indicator on the elevation turret provides quick visual
and tactile reference of the elevation turret’s rotational position. As
the turret enters the second turn of rotation, the indicator will extend
outward from the turret. On the third turn of rotation, the indicator
will be fully extended.
Note: Some combinations of rifle, base and rings may not allow a second
or third rotation of the elevation turret.
Locking Side Illumination Control
The Vortex Razor HD riflescopes use a variable intensity reticle
illumination system to aid in low light performance. Integrated on the
side focus dial for easy access, the illumination can be set and locked
at your preferred setting.
To activate the illumination, pull out the dial and adjust by rotating
the adjustment dial in either direction. The illumination dial allows
for 11 levels of brightness intensity; an off click between each level
allows the shooter to turn the illumination off and return to a favored
intensity level with just one click.
Image Focus and Parallax Correction
The Razor HD Gen II riflescopes feature a side focus dial which should
be used to fine-tune the image focus. When the image is sharply
focused, parallax error will also be eliminated.
Using the Side Focus
1. Be sure the reticle is correctly
focused (see Reticle Focus section on
page 6 ).
2. Turn the side focus knob until the
target image is as sharp as possible.
The yardage numbers referenced on
knob should closely match the actual
yardage to the target.
3. Check for parallax error by moving your head back and forth
while looking through the scope. The focus is correct if there is no
apparent shift of the reticle on the target. If you notice any shift,
adjust the focus knob slightly until all shift is eliminated.
Parallax is a phenomenon that results when the target image does not
quite fall on the same optical plane as the reticle within the scope.
This can cause an apparent movement of the reticle in relation to the
target if the shooter’s eye is off-centered. Correctly focusing the target
image will allow it to fall on the same optical plane as the reticle
within the riflescope.
This Razor HD Gen II riflescope features the fast, accurate, easily-read
L-TEC elevation and windage turrets with integrated locking mechanisms preventing accidental adjustments. The
turrets feature the L-TEC zero stop which provides a reliable return to the
original zero when long distance shots have been dialed. Note: The turrets
will allow a slight over travel (1/2 mrad or 1.25 MOA) for shooters who occasionally need to dial down below
To make adjustments:
1. Pull the windage or elevation turret knob outwards to disengage the
2. Turn the knob in the desired direction: up or down for elevation
adjustments; left or right for windage adjustments.
3. After the shot, return knobs to the zero position. The elevation turret
can simply be spun clockwise until reaching a hard stop against the
zero stop. Then, turn the elevation turret just slightly (1/2 mrad or 1.25
MOA) in a counter-clockwise direction until the 0 mark on the cap
lines up with the indicator mark on the turret body.
4. Push turret knobs inwards to return to the locked position.
Each click of the Razor HD turret will move the point-of-impact either
.25 MOA or .1 mrad depending on the model. (Refer to MOA and MRAD
Adjustments on page 5 for more details).
Adjusting the L-TEC Turrets for Bore and Range Sighting
Prior to making any zero adjustments, be sure the L-TEC turret caps are
correctly positioned with the 0 mark on the turret cap indexed to the
reference line on the turret body.
• Lift the elevation turret cap and rotate turret clockwise until it hits
a hard stop. Then, rotate just slightly (1/2 mrad or 1.25 MOA) in a
counter-clockwise direction until the 0 mark on the cap lines up with
indicator line on the turret body. Once aligned, push the cap back
• Lift the windage turret cap and rotate until the 0 mark on the cap
lines up with indicator line on turret body. Depending on previous
cap orientation, you may have to rotate either clockwise or counterclockwise to do this. Once aligned, push the cap back down.
Steps for Bore Sighting and Range Sighting
Be sure the L-TEC turret caps are correctly positioned with the 0 mark
on the turret cap indexed to the reference line on the turret body (see
5. Once desired zero has been achieved, re-tighten three set screws.
For best performance, turn in each of the three set screws until lightly
seated. Then, go back and continue to turn each screw a little bit at a
time until all three are fully tightened down.
6. Replace the turret top cover.
To get the best performance from your Vortex Razor HD riflescope,
proper mounting is essential. Although not difficult, the correct steps
must be followed. If you are unsure of your abilities, it would be best to
use the services of a qualified gunsmith.
Rings and Bases
Mount an appropriate base and matching rings to your rifle according
to the manufacturer’s instructions. The Vortex Razor HD riflescopes
require 34 mm rings.
Vortex Optics highly recommends using the Vortex Precision Matched
34 mm ring sets which may be purchased from an authorized Vortex
riflescope dealer. These rings will mount to any Picatinny spec base.
If using an aftermarket base and ring setup, use the lowest ring height
that will provide complete clearance of scope and rifle—avoiding any
contact with barrel, receiver, bolt handle or any other part of the rifle.
A low mounting will help assure proper cheek weld, aid in establishing a
solid shooting position, and promote fast target acquisition.
Eye Relief and Reticle Alignment
After installing the bottom ring halves on the mounting base, place the
riflescope on the bottom ring halves and loosely install the upper ring
halves. Before tightening the scope ring screws, adjust for maximum eye
relief to avoid injury from recoil:
1. Set the riflescope to the middle of its magnification range.
2. Slide the riflescope as far forward as possible in the rings.
3. While viewing through the riflescope in a normal shooting position,
slowly slide the riflescope back towards the shooter’s face—paying
attention to the field of view. Just as the full view is visible, stop.
4. Without disturbing the front-back placement, rotate the riflescope
until the vertical crosshair exactly matches the vertical axis of the rifle.
Use of a reticle leveling tool, a weight hung on a rope, flat feeler gauges,
or bubble levels will help with this procedure.
5. After aligning the reticle, tighten and torque the ring screws down
per the manufacturer’s instructions.
Initial bore sighting of the riflescope will save time and money at the
range. This can be done by using a mechanical or laser bore sighter
according to the manufacturer’s instructions or by removing the bolt and
sighting through the barrel on some rifles.
To visually bore sight a rifle:
1. Place the rifle solidly on a rest and remove the bolt.
2. Sight through the bore at a target approximately 100 yards away.
3. Move the rifle and rest until the target is visually centered inside the
4. With the target centered in the bore, make windage and elevation
adjustments until the reticle crosshair is also centered over the target.
Note: Be sure to read pages 11–12 prior to making adjustments.
Final Range Sight-In
After the riflescope has been bore-sighted, final sight-in should be done at
the range using the exact ammunition expected to be used while shooting.
Sight in and zero the riflescope at the preferred distance. 100 yards is the
most common zero distance, although a 200 yard zero may be preferred for
long range applications.
Be sure the reticle is in focus (see Reticle Focus section on page 6) and
adjust the side focus knob if present until the target image is sharp and
without parallax error (see Using the Side Focus section on page 8).
1. Following all safe shooting practices, fire a three-shot group as
precisely as possible.
2. Next, adjust the reticle to match the approximate center of the shot
group. Be sure to read page 11–12 prior to making adjustments.
Note: If the rifle is very solidly mounted and cannot be moved, simply
look through the scope and adjust the reticle until it is centered on the
3. Carefully fire another three-shot group and see if the bullet group is
centered on the bull’s eye.
This procedure can be repeated as many times as necessary to achieve a
The fully waterproof and fogproof Vortex Razor HD riflescope
requires very little routine maintenance other than periodically
cleaning the exterior lenses. The exterior of the scope may be cleaned
by wiping with a soft, dry cloth.
When cleaning the lenses, be sure to use products, such as the Vortex
Fog Free cleaning products or Lens Pen, that are specifically designed
for use on coated optical lenses.
• Be sure to blow away any dust or grit on the lenses prior to wiping
• Using your breath, or a very small amount of water or pure
alcohol, can help remove stubborn things like dried water spots.
All components of the Vortex Razor HD riflescopes are permanently
lubricated, so no additional lubricant should be applied.
Note: Other than to remove the top turret cover for zeroing purposes,
do not attempt to disassemble any components of the riflescope.
Disassembling of riflescope may void warranty.
Many times, problems thought to be with the scope are actually mount
problems. Be sure the mounts are tight to the rifle and the scope is secured
so it doesn’t twist or move in the rings. An insufficient windage or elevation
adjustment range may indicate problems with the base mount, base mount
holes drilled in the rifle’s receiver, or barrel/receiver alignment.
Check for Correct Base and Ring Alignment
1. Center the scope reticle.
2. Attach bore sighter, or remove bolt and visually bore sight rifle.
3. Look through the scope. If the reticle appears way off center on the
bore sighter image or when compared to the visually centered target when
looking through rifle’s bore, there may be a problem with the bases or rings
being used. Confirm that correct base and rings are being used—and in
the proper orientation.
There are many issues that can cause poor bullet grouping.
• Be sure that rings are correctly torqued per the manufacturer’s
• Be sure that all screws on rifle’s action are properly tightened.
• Be sure rifle barrel and action are clean and free of excessive
oil or copper fouling.
• Maintain a good shooting technique and use a solid rest.
• Some rifles and ammunition don’t work well together—try different
ammunition and see if accuracy improves.
