A riflescope indicates a bullet's point of impact and makes distant targets
and surrounding objects appear closer. A riflescope is recommended for safer,
more accurate shooting in the field and on the range.
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 transmission.
TYPES OF COATINGS
- A single layer on at least one lens.
- A single layer on all air-to-glass surfaces.
Multi-Coated - Multiple layers on at least
one lens and all surfaces are coated at least once.
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 4x40 model has an exit pupil of
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 field of
Objective Lens Size
Riflescopes are often referred to by two numbers separated by an
"x." For example: 4x40. 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 unaided eye.
The second number in the formula (4x40) is the diameter of the objective or
front lens. 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 his head or, in extreme cases,
as an out-of-focus image. Bushnell centerfire riflescopes under 11x are
factory-set parallax-free at 100 yards; rimfire and shotgun scopes at 50
yards. Scopes of 11x or more have a special range focus to adjust for
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 100 yards) or
finer windage and elevation adjustments with audible clicks for greater precision.
Now the hunter won't miss the shot of his life by accidentally breathing on
his eyepiece while aiming. RAINGUARD is Bushnell's exclusive, patent pending,
hydrophobic (water-repellent) coating that causes condensation from rain, fog
or snow to form in much smaller droplets than on standard coatings. Smaller
droplets scatter less light, resulting in increased light transmission and a
much clearer sight picture. Also, water sheets off RAINGUARD much more
readily than off a standard coating.
Resolution, or definition, is the ability of a scope to distinguish fine
detail and retain clarity.
Bushnell riflescopes use high-durability aluminum alloy formed into a
one-piece tube. They are also anodize finished and are sealed to protect the
inside from the elements. Each riflescope is rustproof, virtually
scratch-proof and a beautiful complement to the most expensive rifle.
Sealed, Waterproof and Fogproof
Bushnell riflescopes remain crystal-clear in all types of weather. All
1" and 30mm diameter riflescopes are not only nitrogen-purged to remove
any vestige of internal moisture, but they are also O-ring sealed to prevent
the entry of dust or moisture.
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
The inner workings of a scope have a direct affect 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.
power - (example:
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.
power - (example:
3-9x40, 2.5-10x50) Select these riflescopes for hunting big game at medium
power - (example:
6-18x40, 6-24x40) These riflescopes are best for target shooting, when the
target is motionless and for varmints and other small game.
TYPES OF RETICLES
A reticle is the crosshair
or pattern placed in the eyepiece of the scope to establishe the gun's
position on the target.
