Coatings on lens surfaces reduce light loss and glare due to
reflection for a brighter, higher-contrast image with reduced
eyestrain. Bushnell® riflescopes are coated with a microscopic
film of magnesium fluoride. More coatings lead to better light
- Coated – A single layer on at least one
- Fully Coated – A single layer on all
- Multi-Coated – Multiple layers on at
least one lens surface.
- Fully Multi-Coated – Multiple layers on
all air-to-glass surfaces.
The size of the column of light that leaves the eyepiece of a
scope. The larger the exit pupil, the brighter the image. To
determine the size, divide the objective lens diameter by the
power (a 4x32 model has an exit pupil of 8mm).
The distance a scope can be held away from the eye and still
present the full field-of-view. Bushnell riflescopes provide
an extra margin of comfort and recoil safety with extended eye
relief and soft neoprene eyepiece guards.
The side-to-side measurement of the circular viewing field or
subject area. It is defined by the width in feet or meters of
the area visible at 100 yards or meters. A wide field-of-view
makes it easier to spot game and track moving targets.
Generally, the higher the magnification, the narrower the
A combination optical configuration using lenses and mirrors
to create a total scope length much shorter than the total
focal length of the system. This provides a compact design
yielding long focal length performance.
Riflescopes are often referred to by two numbers separated by
an "x". For example: 4x32. The first number is the power or
magnification of the scope. With a "4x", the object being
viewed appears to be four times closer than when seen with the
Objective Lens Size
The second number in the formula (4x32) is the diameter of the
objective or front lens in millimeters. The larger the
objective lens, the more light that enters the scope, and the
brighter the image.
The lens closest to your eye.
A condition that occurs when the image of the target is not
focused precisely on the reticle plane. Parallax is visible as
an apparent movement between the reticle and the target when
the shooter moves their head or, in extreme cases, as an
out-of-focus image. Bushnell center fire riflescopes under 11x
are factory-set parallax-free at 100 yards; rim fire and
shotgun scopes at 50 yards. Scopes of 11x or more have an
adjustable objective to adjust for parallax.
The windage and elevation adjustments affect accuracy. Windage
is the horizontal (left-to-right) adjustment, usually the side
turret of the scope. Elevation is the vertical (up-and-down)
adjustment, usually the top turret of the scope. Bushnell
scopes feature 1/4 M.O.A. (1/4" at 1 windage 00 yards) or
finerand elevation adjustments with audible clicks for greater
Resolution, or definition, is the ability of a scope to
distinguish fine detail and retain clarity.
How To Choose
A quality riflescope is the key to a successful day at the
range or in the field. Riflescopes bring distant targets and
surrounding objects up close and personal allowing safer, more
accurate shooting. They gather and utilize available light
making it possible to shoot in lower light conditions and
allowing the hunter to hunt from dawn to dusk.
Pairing just the right riflescope with your gun and ammunition
will help you get the most out of each and every shot.
Selecting the correct scope to fit your needs involves a
number of considerations from mechanics and construction to
image quality and magnification. Keep in mind when and where
you shoot most often and choose a riflescope with features
that best fit the requirements of your particular sport.
The inner workings of a scope have a direct effect on shooting
accuracy. As adjustments are made during sight-in, the cam
tube, which holds the reticle and lenses in place, moves
inside the scope. To stay on target and produce a quality
image, this tube must be strong enough to absorb the impact of
heavy recoil during shooting and remain in place. When
selecting your riflescope look for precision (positive)
adjustments, point-of-impact consistency, reticle strength and
waterproof, fogproof and shockproof durability. You'll also
want to consider weight, bulk and ergonomics, which are
especially important during long days in the field.
For optimum image quality, it is important that the optical
system of a riflescope deliver as much light as possible to
the eye of the shooter. The lighter or brighter the image, the
sharper the resolution and the clearer the shot. The quality
of the glass, lens design and optical coatings all contribute
to a riflescope's ability to manage light effectively. When
selecting your scope, consider magnification, objective lens
size, exit pupil, resolution, field-of-view and eye relief.
Choose a riflescope with the magnification or power that is
appropriate for your particular application.
- Low Power – (examples: 1.5–6x32,
2–7x32) These riflescopes are ideal at close range and for
shooting moving targets. They provide the most effective light
management and produce a brighter sight picture and wider
field-of-view – even in low-light conditions and thick brush.
- Medium Power – (examples: 3–9x40,
2.5–10x50) Select these riflescopes for hunting big game at
- High Power – (example: 6–18x40,
6–24x40) These riflescopes are best for target shooting, when
the target is motionless and for varmints and other small
