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 riflescope, to assure there are no rough spots or burrs to interfere with perfectly smooth operation. The NXS™ titanium spring has been optimized for a lifetime of performance, designed to never reach its fatigue limit or establish a memory, even if the setting is unchanged for long periods of time. 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 bonding 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.
