Nightforce Scope Technology

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. 


 

 

 

 

 

 

 

 

 

 

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.

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. 

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 160o F 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.
