| You cannot buy a higher quality
riflescope.
That’s a strong claim, without a
doubt. But, it’s a claim we can
prove. And our customers do prove
it… every day, under some of the
harshest, most unforgiving
conditions on earth.We didn’t start
building scopes and expect people
to find uses for them. Instead, we
looked at real-world needs. Needs
that were not being met by other
optics. And created, from the
ground up, the ultimate precision
instrument for the intended
application.You can tell the
difference the moment you pick one
up. And if you could look inside a
Nightforce scope, the differences
would be even more obvious.
Fortunately, just looking through
one will tell you just about
everything you need to know.
Our riflescopes are subjected to
abuse during product development
that would quickly destroy lesser
optics. Pre-production riflescopes
are tested in a pressure tank
simulating 100 feet of water for 24
hours, ensuring absolute waterproof
integrity. We test thermal stability
by freezing them to -80ºF, then
heating them to 160ºF within a one-
hour period. Function is checked at
both temperature extremes. Recoil
and impact testing for positive and
negative forces is conducted at
1,250 Gs.
Before it is shipped to a customer,
every riflescope is completely
inspected and checked at 70 to
130 different points, depending on
the model. We perform a battery of
tests, including forward impact, side
impact, tracking accuracy and
resolution integrity. These are but a
few of the steps we take to ensure
absolute quality before any
riflescope leaves our facility.All air-
to-glass surfaces receive our
proprietary broadband multi-
coating; applied to tolerances of
1/4 wave deposition or .000005
inches, exceeding the toughest Mil-
Spec abrasion test. You will see the
difference in low-light
situations. Every lens in a
Nightforce scope is matched and
aligned by hand perfectly to its
partners. This technique, called
optical indexing, yields the highest
possible optical performance.
Because it takes time and
considerable expertise, many
manufacturers don’t bother. We’ve
done it this way since the beginning.
A scope’s objective lens
determines resolution, light
transmission and exit pupil size. To
maximize these attributes, every
Nightforce objective lens assembly
utilizes a multi-element design like
those found in the highest quality
telescopes. Our lens system
focuses light rays more precisely
for exceptional image clarity and
color accuracy. Nightforce tubes
are machined from solid bar stock
6061-T6 aircraft-grade aluminum
alloy, not extruded or formed like
those found on lesser scopes. They
are two to three times thicker than
other riflescopes. This means less
overall stress, greater thermal
stability, a consistent zero and a
virtually impervious shield for the
precision optics within.
The spring that maintains pressure
on our elevation and windage
adjustments spends two weeks in a
polishing tumbler before going into
a Nightforce scope, to assure there
are no rough spots or burrs to
interfere with perfectly smooth
operation. It is made of pure
titanium, the only known metal in
the world that can be repeatedly
compressed and held in place, even
for years, without developing fatigue
or “memory.” This guarantees zero
loss of integrity, zero loss of
repeatability. It is many times more
expensive than comparable springs
found in most scopes. But, we are
not concerned with a few dollars.
We are concerned with building the
best riflescope.
The terms “rugged” and “precision
optics” are usually not compatible.
Any optical instrument built to
highly exacting tolerances and
absolute alignment is by its very
nature a delicate device.
Not so with Nightforce.
The design of our scopes is unique
within the industry, allowing us to
combine optics of extraordinary
precision with construction that will
withstand repeated recoil from the
largest calibers, extreme shock and
severe temperature changes.
We machine the screw that controls
elevation adjustments to an
unbelievable 110 threads per inch.
It is so precise that it must be
mated to its receiver by hand. Why
go to so much trouble? Because we
consider backlash clearance of
more than 1/30 the thickness of a
human hair unacceptable.
Available with Nightforce ZeroStop
technology that allows an absolute
return to your chosen zero point,
regardless of how much you have
adjusted elevation settings. MORE
INFO…
Sand, dust, mud, heat
and cold are a few of the
environmental challenges every
Nightforce scope faces in its
development. Every aspect is
thoroughly tested, proven, and
tested again before we build a final
product. Anything you can inflict
upon a scope, you can be certain
we’ve already done it first.
Turret adjustments are made with
hardened silicon bronze to ensure a
lifetime of wear resistance and
reliable performance.
This combination is not the easiest
way to build a scope. It is,
however, the best way to build a
scope, providing a lifetime of
repeatable accuracy.
Lenses are painstakingly bedded
and cemented with our own
proprietary Mil-Spec formulation.
There is no glass-to-metal contact
that can result in breakage or
misalignment over time. Most other
manufacturers use simple lock
rings. But, what is acceptable to
other manufacturers is not
acceptable to us.
The optical elements
within an NXS scope are hand-
bedded with our own proprietary Mil-
Spec bon-ding agent, then cured at
160ºF for 24 hours. Lenses are
further secured with o-rings and
machined metal lock rings, both
fore and aft. This zero tolerance
lens securing method assures no
possible movement of the optical
elements from impact in any
direction, including side impact.
Every lens cell in every Nightforce
scope is fully tested to make
certain it meets our rigid standards
for quality and long-term reliability. |
