While the original design was influenced by the U.S. military’s needs for extreme long range shooting and hard target interdiction, the NXSTM 5.5-22x has been a favorite of sportsman and law enforcement as well. Both 5.5-22 Nightforce NXS™ models provide a broad magnification range, excellent eye relief, and 100 MOA of elevation travel.

These characteristics, combined with the extreme ruggedness and reliability of every Nightforce riflescope, make them ideal for even the largest calibers. The slim profile of the NXS™ 5.5-22 x 50 makes it easily adaptable to a wide range of mounting systems.

Its superb resolution at high magnification opens an entirely new world of extended range shooting for the accomplished marksman; Nightforce shooters are now accurately reaching to 2000 yards and beyond.

Nightforce ZeroStop™

An Instant Return To Zero. Every Time

It’s an old problem. Make a radical adjustment to your scope’s elevation settings and returning to your zero setting can be almost impossible. Other manufacturers have tried various means to solve this problem, with less than satisfactory results. The Nightforce ZeroStop™ is the solution. A solution so good, so simple and so effective, it is patented.

After sighting in your rifle, simply set the ZeroStop™, and you create a positive mechanical stopping point at your chosen zero point. Then, no matter how many elevation adjustments you make, turning the elevation knob down to the ZeroStop™ setting returns you to your original zero, completely by feel—even in total darkness or while wearing gloves. No counting clicks, no need for visual reference, no wasted effort. Just an instant return to zero. Every time.

ZeroStop™ is standard on ATACR models, The B.E.A.S.T., Competition, and most NXS models. ZeroStop is optional on 1-4, 2.5-10x32. Available in .250 MOA and .1 Mil-Radian adjustments.

Building a Nightforce

Nightforce's journey began in 1992, in a quest to provide the ultimate in riflescopes and accessories to the hunter, the professional, and the competitive shooter.

Consider the challenges of making a Nightforce riflescope. Optically, you are creating an instrument of extreme precision, built to tolerances often finer than a human hair. It requires many of the same techniques used in the very best laboratory microscopes and in massive, delicately balanced scientific telescopes that peer deep into the heavens.

Then you’re tasked with putting these perfectly matched optics into the most compact package possible, eliminating every ounce of excess weight, and making them impervious to extreme weather conditions as well as to constant pounding from the most powerful rifle calibers over thousands of rounds. It is a huge technological challenge. Frankly, there are very few riflescope companies up to it. Fortunately, Nightforce are.

Factory Testing: Before they leave the factory, Nightforce riflescopes are subjected to conditions far beyond most anything you will ever encounter in the field. During Nightforce's impact tests, riflescopes must endure repeated impacts of over 1200 Gs of force on multiple axes. After each severe impact, the riflescope is hand-checked on a collimator for tracking accuracy and overall integrity. If Nightforce can’t make it fail, chances are you can’t either.

Turrect Tracking and Consistency: If a scope manufacturer even bothers to check for turret accuracy–and many don’t–they often allow a “tolerable” error or don’t verify accuracy over the entire adjustment range. At Nightforce, “good enough” is not good enough. During the manufacturing process Nightforce inspect their scopes to ensure perfect clicks and absolute precision across the entire range of adjustment. This means that when you make a shot at any distance, regardless of how much windage or elevation adjustment you’ve made, you can trust your turrets–and your Nightforce–to deliver your shot predictably and on target.
