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 rif lescope 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 rif lescope for bullet
trajectory.

MOA Models

“1 Click = 0.25 MOA”

MOA Adjustments

MRAD Models

“1 Click = 0.1 MR AD”

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 Adjustments

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
meters), etc.

Reticle Focus

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
stare.

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.

Warning

Looking directly at the sun through a riflescope, or any optical
instrument, can cause severe and permanent damage to your eyesight.

Adjust the reticle focus.

Variable Power Adjustments

To change magnifications, turn the magnification ring to the desired
level.

Adjust the magnification.

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.

Turret in second

Note: Some combinations of rifle, base and rings may not allow a second
or third rotation of the elevation turret.
